@@yagmanx I know I'm super late here but on the subject of that plant (and other models with similar poly count issues): On your decimate modifier at 7:19 you could select the "Planar" option and set its Delimit mode to "UV". This would decimate the model whilst performing calculations favoring the original UV layout more than other options would. Obviously not as good as making a low-poly version yourself, but it's a closer result that can work just fine with many basic props.

This is so extremely helpful! When I'm watching other devlogs they always get to a point where they simply "optimize", but they never explain what there doing!

I'm maybe a bit late on this video but one thing that helped me a lot when i started, was learning about Object Pooling. Basically if you have certain objects that have to appear and then disappear frequently (like enemies for example that appear when spawning and disappear when dying), instead creating and destroying the object simply activate it and deactivate it. Usually i have a script that manages a certain amount of objects that are deactivated on the start of the game and when i need one or multiples of it, I ask the ObjectPoolManager for those objects, set them active, set up any components they might need, initialize their starting parameters and send them on their way. And if they have to disappear, just deactivate them because the ObjectPoolManager has a reference to them and can easily find them for future activation.

Great video! I know it’s been a lot of work to get it to this level of performance, and I commend you for your hard work and dedication. It’s not easy to go back to an old project and work on it again after many months/years have gone by, so amazing work! I work as an engine programmer myself and, as you can imagine, performance matters a lot to me. So for me it was really nice to see a video like this and I hope you continue your journey into optimizations and performance. If you’re interested, one of the things you can look into is Data-Oriented Design. It’s a pretty interesting topic (at least to me😅) that approaches performance in terms of hardware characteristics and how memory works under the hood. I know Unity has an implementation of an ECS nowadays (which uses Data-Oriented Design principles behind the scenes). I don’t know how good or practical the implementation is, because I’ve never used it myself, but I believe they’ve really focussed on it heavily in recent years. So that might also be an interesting area to explore in the future.

Hey there, just an extra tip. I see a lot of professional games using different meshes for an object visual aspect and its collisions. Making a simpler more lightweight mesh for an object's collisions could help you optimize the game a bit while keeping mesh colliders.

@bradjones7491

Жыл бұрын

@@0xlapras646 I mean you would just have to look up how to do it from scratch, but checking boundaries of a cube is mathematically significantly simpler than check the bounds of a complex mesh. for example you could easily determine if a point falls within a volume of 1, but a mesh collider has a non standard volume so you would first have to determine the volume before checking the bounds. Mesh colliders are used extremely sparingly in general, and mostly just for simple shapes like ramps and sometimes terrain. As for the extent of the difference I couldn't say for sure but I'd assume it would be fairly significant since almost every AAA game in existence utilizes the multiple simple colliders method. Mesh colliders should only really be used when the alternative is prohibitive, such as with a massive object like a terrain, where aligning individual colliders would take thousands of hours. Basically mesh colliders are time savers, but are overutilized by people who get lazy, and by doing just a bit more manual setup you can often avoid the additional overhead. Another thing to consider is that often times mesh colliders fail at detections where a box collider would not. While it's pretty unordinary and example of this can be achieved by moving an object at incredible speeds, if the wall is a mesh collider it has a significantly higher rate to allow the object to pass through than a cube. and This is because mesh colliders don't really have thickness so if the physics calculation somehow places that object on the other side then the collision will not be detected, whereas with a cube the object would need to reach significantly higher speeds to breach it's entire bounds, and you could make a wall have theoretically infinite thickness to make it basically impossible to clip into. As a side note about the fail rate of physic detection this mostly occurs because physics calculations are done on an independent update loop that has it's own time scale so a significantly large movement in a single update of that tick function could offset the object further than the collision is detecting thereby avoiding the collision detection entirely. This is because most physics systems don't calculate along the traveled vector when determining collision, rather they only check for the position at that frame of the tick update. That is to say, that if an object moves farther than the entire collision's size in less than 1 physics update tick, then that collision will not be detected. That also leads into another slight tangent about unity in particular, where people think that unity's physics engine is very inaccurate, but this is actually mostly caused by people never changing their physic's tick rate under the time settings in unity. By default I believe it is set to a tick rate of 0.10 which is 10 frames per second and is pretty inaccurate, allowing for most "fast" speeds to easily clip through collisions.

Thank you , you have no idea how much this helped and on what project!!! You are amazing have a great day.

Really informative! Gret work putting this together

As for LOD'ing, I find it better to have the high quality / mid quality / absolute low quality. Mid quality should be the default, high should only be shown in either cutscenes or when very close to the model, so make sure your decimated models are in the 'mid' quality to make it the default. Low quality should be barely there, just to indicate that something's there. The best way to verify LODs is by switching to wireframe mode (or use wireframe selection) and move the camera backwards until the wireframe becomes a solid color, then you can switch to a lower LOD. I've seen asset store models that use like 5 LODs which is doing its job to optimize, but not as good as it COULD be, by having that many different models compared to all the vertices rendered at real time, the 2nd and 4th LODs will barely make any difference, but just add heap to memory, which as I said, still optimizes, but it nerfs the potential result.

If I understand the problem correctly about the collision thing at 22:15 you might want to do a distance check between the object and the player first to see if the object is even close enough to worry if its colliding. If the player was moving really fast that might cause the player to move right through things but it didn't seem like a problem your game would deal with.

Great video 🧡. I have one tip for artists and one for programmers: Here's a tip for any artist who is going to attempt to make a game - TAKE A COURSE IN PROGRAMMING! I work with and have had to optimize levels created by artists who didn't know the meaning of the word "performant". So please just take a small course in programming. It'll help you immensely. And for all the programmers out there, here's a different tip : complex =/= good. Don't write extremely complex, hard to read code if you can achieve the same result by simpler, more basic means. Keep It Simple and Stupid - K.I.S.S There are so many Unity store assets that are just horrible when used without thinking - both in terms of art assets, AND in terms of tools and systems. You would be surprised at the number artists who don't know what being performant means, and ALSO, you would be surprised at the number of programmers who don't know how to keep code simple and clean.

Great video on some optimization fundamentals. I'd also look into Tasks as an alternative to coroutines. They offer things that coroutines can't like return values, and they work asynchronously so you can await on them. A little bit trickier to implement, but you won't be sorry for learning it. Also, Camera.main will return you the main camera, so you don't need to FindObjectOfType, but a better approach may be to use a singleton pattern to manage things you need direct access to, or a static class which can store information you use consistently. Great video though and good luck with your game :)

8:56 this is really Important for 3D Artists this was exactly the reason why my first game couldn't get higher than 20 fps I build my whole level in MAYA because my teacher never told me there is something called draw calls and the general workflow of 3D Assets / props for Game Engines My 3D models where optimized af and I didn't understand why my ~1000 poly assets killed the performance. No one told me the workflow that you usually only export the .fbx, then create a prefab / blueprint in Unity and not drawing every mesh multiple times into the scene and instead reuse them. Also a big problem was the materials. Materials are probably the main reason your fps drop like sh*t. Using multiple materials for example on a chair and not using base materials that can be drawn on many different assets for stuff like wood, metal etc. killed my performance. Before I knew there was something called color IDs I created a material for every single thing that had a slightly different color. And with over 200 Materials (2048px) I know now why I had 20 fps.. anyways I didnt understood why my relativ small scene had such bad performance but after hearing about drawcalls, materials optimization and a work of 20h we finally got a good performance ^^

I always like to do a quick performance test after adding anything so that I intuitively know what's draining performance

Doing some research before deciding whether to embark on my own game development journey. This has shown me there's a lot more to understand 😂

I'm very happy to hear this and totally agree! I use Unreal too and learning all of these techniques myself has definitely helped keep my Unreal projects performant

What I would add, and I know that my comment is a couple of years late but... One of the things I learned in optimizing our games was 1) use object pooling; and 2) never let the system do it's own Garbage Collection. Managed code, especially on non-pc platforms, will wait until the absolute last minute and then Collect. This invariably results in it dropping fps down to about 5fps for a second or two (dependent on the amount of garbage that the game makes). What you can do instead - put your own garbage collector (GC code) into a coroutine, and then adjust the timing to strike the best balance. (To anyone new, you don't want to run you GC every frame, because it has its own overhead; hence finding the optimal balance.) This is especially important if you destroy a lot of objects, especially ones that cannot be pooled. Like destructable scene objects, those wouldn't be pooled. Hope this helps out!

New subscriber here, great job.

Very good video! I do a lot with modeling and building worlds for VR Chat and when using Unity, it can be a lot to get the max performance I want! I plan on doing Blender tutorials on how to build great models for low cost on performance 🙌 LOD is really good too and worked magic when I was making a corn field that would be rendered in a VR Headset such as a Oculus Quest

19:36 i know its a bit late to respond but in case someone need it: the use of "find" in the "awake" will not necessarily degrade the performance of your game. it depends on what script using it. if you use "find" in a singleton, it will be fine. just don't use "find" in a script attached to dynamic game object. another thing, if possible, try to use "FindObjectOfType" instead of "Find". i use "find" in the awake method of my level scene. although its not a singleton, but i consider it safe to put it there. no one will notice additional 0.5 sec delay during the scene loading :D

Great video, one of the best optimisation videos Ive seen in ages, and I actually learned something (after 11 yrs with unity). Im still not clear on how collisions work it seems, you say mesh collider is expensive, I hear it time and time again, but I somehow thought that collisions were only checked when you get near or something. Do you think any collider on screen is constantly checking for collision? If so Im probably wasting a ton of cycles on that too, I wonder how feasible it would be turn on only colliders near you and keep them off other times. If NPCs had a navmesh it shouldnt matter if theres real colliders or not. You see Im lazy too I really dont want to go around putting cubes on things, and to be honest I want them to react like mesh collider, ie not a cube lol.

Only with an object that is using a rigidbody. Honestly, Unity can handle tons of objects with Mesh Colliders with no performance issues. I mean they do have ProBuilder integrated as their default object building program these days and every ProBuilder object you create has a Mesh Collider on it be default. I have a game that has 10's of thousands of Mesh Colliders and I get well over 60fps. It isn't something to worry about. If you're using detailed imported models then no, you don't really want to use Mesh Colliders on them.

Great video and very helpful, i struggled in my game when i used a second camera for water reflection; im gonna see if i can turn it off and only use it when the player is near by, but the problem is that my game is multiplayer so its kinda tricky and its a racing game. What im worried about is that when the player is near the water and the cam turns on, he would get a sudden loss of fps. Guess i would have to try and see how it looks. As for a side note, i prefer to avoid using many public variables (min 20:54), only when need to be read by other script, and use instead SerializedField, as it shows in the inspector as well and can drag and drop keeping it private. Example: [SerializeField] private GameObject myObject;

The global personality data workaround fixes the framerate issue, but introduces weird dependency issues. No bigs for a little game, but in a big game or if you want reusable code, you don't want your player to be controlling external systems. You can run into issues where multiple scripts are editing the same global values on top of one another, adding/removing/changing these external systems forces you to edit every script that references them, and if you want to bring the player script into a different game, you either have to bring the entire dependency chain, or refactor the player. A message bus (observer pattern style) is a great solution. Your player broadcasts that it jumps and any object listening for a "player jumped" event will do their thing. The player doesn't care who's listening, so the only dependency is the bus architecture. This will also help with juggling find commands.

Hello, perhaps if something is not active in your scene or a script hasn't been activated yet then you can turn off other things in your scene based on a specific variable rather than relying on those collision boxes to turn off others. So basically a variable can be changed when someone enters a door and the code can check if the door script is now active or if the variable is true ( for example) and then have it effect another variable which will turn certain collisions off (once again, for example).

Setting up game events might be better than setting variables that need to be frequently checked. var doorOpened = new Event(); void DoStuff() { // stuff } doorOpened.AddListener(DoStuff); void OnDoorOpened() { doorOpened.Invoke(); } The example could be better but I'm not at my PC. Worth checking out, though :)
