And now i have a question, what’s a big game ?

@johnleorid

2 жыл бұрын

After uploading I realized I never specified it in the video. Basically every game where you have a big enough (or complex enough) connected game world that you have to load and unload content to achieve 60fps in the build. In my specific case it was when we had more than 3million triangles on the screen while going through the world, at about 100k GameObjects, about a map size of 2km x 1km. At that point lightmapping stopped working, occlusion culling broke, it took 70 seconds to recompile or jump into play mode and we had less than 30 fps. I profiled the game and editor for two months and tried absolutely everything to fix it. This video shows what I've found out. What works and what doesn't work. Recompile time is now about 10 seconds, jumping into play mode 5 seconds, navigating the scene camera is smooth, the game runs at ~70-80fps at 4k with an RTX 3070 and 6-Core CPU and in 2k on many systems (playtesters had no issues). And it's now scaleable, we can add levels without any slowdowns and we can collaborate without merge conflicts (the last point took another month, creating the multi-scene setup).

When using a game with a large open world: keep in mind the problems with float imprecision. If your camera gets away more than like 2000 units from the origin, animations can start to flicker and shake. Look up various methods of "origin shifting" to solve that problem by moving the scene dynamically closer to the origin point.

Well, origin shifting is one way to do it, aswell I know teams have just modified the engine they're using to use double-precision coords (CIG did this with CryEngine to get their space, yknow, space-y without having to deal with MMO synchronized world origin shifting, also Epic did this and UE5 natively uses double precision coordinates out of the box now), and then your distance limit becomes so ludicrous that it's barely even worth considering unless you're making a space sim in which everything must always exist in the same scene at the same time. However, with Unity, you need to pay them ridiculous sums of cash to get access to the source code in the first place to even begin on a change like this (which is absolutely insane on its own and anti-consumer as hell when every single other major engine has source out of the box), so YMMV if using this engine.

@@xanderkyron I never saw this as much of a hassle. The C# code can run just fine logic with using custom double Vectors. Custom Netcode can also use double precision. Just anything that has to do with the client visualization and local physics needs to be converted to 32bit float. But then again, the relevant scene is near the camera anyways. Things further away would be turned off or rendered in a different way (second scene camera to render a scaled down solar system, that is the backdrop when travelling for example). The world in a huge game like Star Citizen is also not just a simple scene with objects plopped in, but a more complex process to generate local scenes on the fly. So its also possible in Unity with the right approach. Of course, just compiling all those systems with using doubles would be the cleaner approach, if the engine allows that.

I noticed this while working on a scene that would move the focus of the scene to a location, which would never be reachable by conventional means, as a way to do some tutorial cutscenes without having to load an entirely new scene... my animated model was shaking like she was on a speedball drug or something. My solution was inevitably to move these constructs closer to the bottom of the terrain mesh. It didn't make any sense to me why the issue was resolved by doing this and it's still not something I completely understand but it is what it is.

I think one of the biggest hurdles (atleast for me) working with larger projects is to say "no" to things I want to have in the game. There is usually sooo much that I want to add to the game, there is a need to mash all those idéas into doable tasks.

Heyho, Game Dev here for Unity. I do a lot of profiling, and we are using Renderdoc. Its an extremely important tool as you can link it to Unity and grab Frames to analyze. It is similar to the Frame Debugger, but much much more indepth. When we started optimizing we were constantly checking our builds, and with Renderdoc we removed about 1/3 of GPU overhead already. One important topic to mention from GPU sides are shaders, lights, shadows and texture sizes. But thats probably a whole other video as well. Great Job otherwise. Grüße

Haha nice message on the end! I’m developing a bus simulator for about five years, there are a lot of things that we learn the hard way haha. I abandoned ProBuilder because some updates broke some of my models. Huge games on Unity will suffer from another problem: the lack of precision on world coordinates. After 10km or so from the origin things will get broken, shadows appear blinking, too much jitter on smaller objects etc. The most common solution is moving everything back to keep the camera near the 0,0,0 position. Unreal Engine 4 includes a setting for that, on Unity there is a great open code called “Floating Origin”. But performance may be bad if there are tons of rigidbodies. I can’t wait to test a custom compiled version of Unreal Engine 5 with 64-bit coordinates. But I’m procrastinating on that.

@@FirstnameLastname-my7bz I'm working at a company. Not small, not big, just a company. XD I would suggest looking for "unity beginner tutorials" and you should definitely start small. My first game was ~12 grey cubes and a horribly animated character to jump from one cube to the next one.

I guess it goes without saying, but if you want to make a big complicated game, you need to be knowledgeable about game development, intelligent, and experienced. Too many inexperienced developers have big dreams of making big games that will be the next [insert open world game here]. I'm 36 now, and I've been doing this since I was about... 15. At this point in my life, I'm more than just a "jack of all trades, master of none," I know most aspects of game development on a deep level. I'm a jack of all trades and master of many of those trades. When I set out to make a big complicated game, the planning phase is monumentally important. I need to plan what the game looks like structurally before I place a single cube down in Unity. I need to have an idea of what the data will be structured like, I need to figure out if I'm going to use virtual texturing, HDRP, URP, how I'm going to pack my textures, what kind of audio fidelity is needed, what the art style needs to be to suit my aesthetic and performance desires, decide how modern the game will be and how that will affect how many people will be able to run it (will I be making a game with baked lighting? Am I making a very modern game that uses no baked lighting and uses ray tracing features exclusively? Is there a level of dynamism in the game that it even warrants real time lighting?)... There's a lot to consider, and if you're only a couple years into game development you might not even be aware of what questions to ask and what to consider, let alone how to consider it. As far as optimization, in my experience I've come to realize that rather than "don't optimize until you need to," time and experience will teach you what optimizations can be done in all kinds of situations, and you should carry those optimizations into EVERY project you do. Because if you optimize (and PLANNED!) your game all along, you won't have to after it's done which can lead to soul-crushing code refactors and bugs on the tail end of your development.

32 here, and I frankly disagree. I am a hobby programmer at best, doing the starts of an MMO here. Knowledgeable about game development, sure. Intelligent, sure... Experienced? Nope... but it helps. But all you really need is basic knowledge, know that you have to optimize, etc. and search up the rest. A plan? Not really. You do need to know an overall goal you want to work towards, but even with huge games, you can still take it step by step. It just needs more prework than most other projects. EDIT: Oh yeah, by pre-work, I more mean the optimization, step by step keeping the game together and not just solve problems at "some point".

mixed lighting means one light illumination works for baked lightmaps for static objects, realtime lighting for dynamic objects, and realtime shadows for all ( or shadowmask for static). it's no better than baked lighting workflow.

Very useful content. Thank you and your patrons :)

I think that, for baked lighting and especially in the example you were showing, that you can split your game into rooms and bake those rooms. You could also create a scene dedicated to this room just to bake stuff or cheking and verifying how everything in this room plays. You could also, I think, develop the room on its own scene so that you can navigate in your environment. I think this particular point was brought up during the Editor Performance video chapter, but I think that adding the tip that you could bake lightings per room or divisions and only rely on realtime lightings on light sources that could span in multiple rooms or object groups. I find the optimising part of a game as interesting as it is crucial. My current computer was made in 2014 and was an average gaming build at the time (meaning a good machine in the broader PC configs) but it's starting to feel less and less powerful for more recent games... especially with indie games. It may seem weird that indie games are harder on the hardware than AA or AAA games. But I think that's even more logical. Big game studios theoretically have more budget to optimise. While indie studios aren't even aware of the performance issues, or do not care enough. I have a will to make my games more accessible to more modest PC configurations, so optimisation is a very important topic to me. My computer can still handle gamedev because of the "extra mile" my friend invested into the CPU at the time. To be honest, when I am downloading the one map demo of an indie game that in itself weighs 12+ GB, I internally suffer. One, because even if my download speed is good, I think that there are still many many gamers that have a less powerful bandwidth. Two, because I know that, even in lower graphic settings, it will most likely have performance issues and few optimisations to offer. It's a general feeling I have and it may be exagerated, but I feel like most of those indie demos would really deserve more optimisations.

Really nice video! Taught me some stuff I didn´t really think about.

Good tips , other things i would add are things like : -caching , if you can cache somthing then fking do it , and if you can reuse an item then do it , i've seen a lot of codebases that had stuff (especially in ui code ) like "if something changed then destroy all UIs/objects and rebuild from scratch" , don't be lazy , react to changes accordingly instead of "rePaInT aLL" on every slight change -speaking of UI , only make interactable the things that matter and disable "raycast target" and "maskable" on eveything by default , i actually made an editor script that does that automatically. -if you can bake or precalculate something in editor or a loading screen then do it, try to take as much work off the game during runtime. -if you are running into a bottleneck with stuff executed in update , try to avoid branching by using a jump table or reformatting the data in a way where you can put it i an array and index into it directly. -if you can express logic with an array lookup , do it - the more generic a solution , the more you account for stuff that you probably wont run into and will just be useless overhead , try to make your solutions as domain specific as possible - if there's a task you can automate or make an editor for then do it , your futur self will help you. -unity can be a really dumb engine that would rather give you a straight forward solution/answer but keep the performance overhead/consequences hidden , do the extra digging .pooling I can keep typing on and on but i am too tired rn , hope this helps tho

I have very little experience with game development, but I do have some experience with other things such as web programming, and always have had an interest in complex systems and understanding game performance. This was a very interesting video even though I don't really plan to make any sort of big game. It is very cool to learn that a lot of techniques are quite manual and rely on the developer to manually write them for the game. This is also reassuring and great to hear in case I do make my own games or even content for other games like VRChat which use Unity. I always have wanted to dig through a performance profiler of many of the games I play to find possible performance improvements. Great video!

Really amazing video, I saved this to rewatch now and then. In my personal opinion, the lightmapper is soooooo time consuming. I've tried so much times to use it, and kinda get to know how to make it work, but honestly it's waay more easier to simply use realtime lighting, and it looks pretty similar. I guess it can be used only in level based games, like portal for example

I'd also recommend looking into texture compression like crunch compression, especially for things like roughness/metalic maps (where you can also reduce the resolution) where the compression is less visible, or masks for special shaders. But generally crunch compression for everything but hero objects won't have an obvious visual reduction. And as a result can take a 10GB game down to like 1GB. Also with URP and HDRP it's ideal to have as few shaders as possible.

You made my day ... started to use an event system to pass paramaters from scene A to Scene B ... but giving a Unique ID its a way cleaner option!

Amazing informative video. We'd like more info about this subject. Big open world games, RPG systems, stream loading, big terrains, scene loading etc. Thanks!

Good video, great points. For my first game I decided to go as big and ambitious as possible. Five years later and I've learned soo much but... still no game lol. I still feel like its just within reach and Unity has come such a long way. Anyways, I find that packaging game areas and sub areas into prefabs and instantiating them at runtime OnCollisionEnter has been the fastest way to build massive levels that run great. AI and Rigidbodies are another issue though. I also decided to include physical objects that can be moved around and put on vehicles, etc. Interesting problems to solve for sure.

I remember similar tips back in the glory days of Blender Game Engine. Lights were a big killer there, so you really had to switch them off when far enough/out of the room. Ultimately, creating Nintendo 64 level of quality will never kill the fun anyway. Graphics are beautiful, but that's not where all the fun comes from at the end of the day.

It is hard to find in youtube videos about actual production/commercial-quality projects. There is a lot of tutorial for beginners but not so much content for solving "real world" problems like these. Hoping to watch more videos like this one.

Use the frame debugger to help with figuring out what is using a lot of draw calls. It would be your best bet for a gpu profiler that comes with unity itself.

How did you go about making preview images for scenes? What does the Switch/Add tab do in the Load/Unload window?

Free, Editing, Locked & Modified are the states of a scene, used for merge-conflict-free collaboration. States are written to a custom server and I am using git hooks to know when a user has pulled or pushed. So based on timestamps I can prevent someone from acquiring a scene that wasn't pulled and also preventing unlocking a scene that wasn't pushed. It's not perfect but with only one branch this solved all our issues.

Preview images.. I just used the scene camera, writing to a render texture, which I then convert to a standard texture and this into a byte array if I remember correctly. When opening the window for the first time after recompile, I convert the (serialized) byte array back to the textures.

Keeping scenes in the Hierarchy has the sole purpose of being able to right-click and load them without the editor tool. Just a backup/alternative. ^^

The switch/add tab let's me jump to the main menu, debug/test scenes and it let's me quickly add the lighting and player scene. With those two scenes I have correct lighting and everything I need to play the game in any scene I want (player & UI are in the player scene. Despite not having any direct references, it's convenient to have those in the same scene)

Great video! I'd love to see a video on Big Game Coding systems

Lol the patreon list at the end killed me hahaha, good video man, keep them coming.

Great video John!

Really want to know more about this Like the better code writing you talked earlier and how to optimise large open world environments with lights and other stuffs

Very well presented information and the Patreon bit at the end killed me haha

That's Amazing information! I'll be rewatching this several times. Interesting that Occusion culling is not effective in large scenes

This is a great video on this topic, and a lot of it applies to other game engines as well!

Just a quick tip. If you don't have the following solutions or workflows. don't make a large level, not even a medium level (depends on the vertices and drawcalls overall) 1, level streaming 2, dynamic occlusion culling

Very good tip, make small projects like you're making big ones before graduating to bigger ones

This is gold! Please keep doing these kind of REX, it's priceless. Did you do a video on the coding part at the end?

Was collecting footage, writing code, doing a lot of research and working on Games (also for the video) in the last weeks and started actually working on the video (in the videocutting software) within the last week. You can ring the bell to get a notification when it's ready and uploaded. ^^

Oh yeah, I'd Definitely want to know more about event systems!

Great video. That ending make me chuckle hard lol.

Great video! Almost all of the tips are sort of a must have in any more or less normal project. Unless you are stamping trash mobile games every week - all of these tips are really useful.

+1 for an event system, great video!

Great content. I'm tired of videos on just small scale games. I want to know about big games! The potential of the engine! The limitations! More please!

Subscribed to see that event system!

This sounds like I'm in the advanced section of game making. Sounds very useful for folks at a high level in game creation. I'm heading back to the basics department.

great video, still new to all this but very informative.

Hey there! I rarely comment but I think you deserve one ;) Very good and interesting videos. What I love about it is , despite beeing about Unity, most of the advices works for all game engine. I'm trying to learn Godot , and depite it beeing a very good engine, it's also one that needs the devs to optimize their games a lot, especially if you are working on 3d games. And I knew some of the stuffs you talked about, but other were really helpful. Liked your videos and I do believe you really deserve it! Nice work! Edit: Also, would totally love a detailed video about optimizing scripts :P

Thanks a lot for your comment :D I'm looking forward to a Code Optimization video, but first I want to share the event system, as it's a very cool pattern (when used correctly). ^^

Good overview of potential problems with Unity development! Nice video. 🙂

You deserve all the subs, Thank you
