The reason why this works is, Cycles (raytracing) is fairly agnostic to polygon counts, but viewport (rasterization) is very bad at handling large polygon amounts. So turn off overlay helps here.

@@ChristopherFraserVFX I've actually asked this question before on when viewport performance in general will improve because 3DS Max/Cinema 4D are just way faster even when presented the exact same object. There's actually a roadmap goal to change the outdated OpenGL engine to Vulkan by about end of 2022. Hopefully that's true and brings 2.5x-5.0x performance, and yuno I'm that confident because Blender has proven to bring amazing features on time and in great fashion.

Oh! I just tested and his also works to make Blender UI actually reasonably performant using LIBGL_ALWAYS_SOFTWARE="1" on Linux (enables OpenGL software rendering which would be necessary to run Blender 2.8+ on older graphics cards that do not support OpenGL 3+)! I guess it wouldn't really enable smooth editing or anything (maybe some kind of shader in Cycles could help?)... but it's _waayyyy_ better than the performance issues I had before when testing this method, when trying to imagine what in the world I would do if my GPU died. Kind of makes me want to do a render challenge of trying to make a beautiful render without using my GPU at all except for display output some time. It works great for displaying massive textures too large to fit on my VRAM too. (Pre-post edit: Actually, looks like editing geometry was never so much of an issue as previewing my large hair systems. Geometry editing is... somewhat slow, but fast enough with software rendering, but previewing the entire scene with lots of particles was ridiculously slow compared to Cycles preview with hardware OpenGL enabled until, per this video, I disabled the overlay) I think the crashing issue you mentioned in the video is mostly a Windows thing, due to Windows not automatically allocating to the swap file when it runs out of RAM. Linux has its own issue where the entire computer can get extremely slow to the point of freezing if one has a lot of swap available and it keeps using more and more of it, but it rarely if ever outright _crashes_. Just adding more RAM can fix the issue on both Windows and Linux, though. I recently upgraded to an insane amount as I got tired of really big things using up all of it, including both Blender and other software like Cities: Skylines, as well as being tired of frequently-accessed files being slow to load. A ton of RAM makes a HUGE difference and I highly recommend it. Lots of RAM means one can run practically anything, even if it may be somewhat slow. You know what RAM doesn't fix though? Lack of VRAM making the GPU slow to a crawl as it uses slow PCI to swap to system memory. Which, this tip will also help a lot with (as mentioned in the video) if the bottleneck is from too much geometry rather than too many textures. Thank you very much for this tip! This will help things quite a bit. You know, this button has been _right there_ the entire time. I wonder what other super useful things in Blender I am missing that are actually pretty obvious if one looks around the UI.

@@ObscureHedgehog A render preview mode, or RT mode, is an interactive render view, where basically a path tracer (GPU or CPU) renders the camera view, with all the render settings applied. Interactive means that the scene get updated on viewport changes, happening not in the render preview. So you have these separated. It also gives you options like, DOF adjustment, material or item picking and LUT. The propose is to see the final render image and not what is displayed in the viewport. This is now a days standard in every software and render I know, just not in Blender. Viewport rendering is different, it takes the resolution of the screen, not of the output and it renders the actually view, either full or framed. Its a technology first introduced with Mental Ray in Softimage.

So you’re telling me Blender doesn’t use proxies? I’m just asking because I’ve been poking around in Blender lately to see all the new features it has to offer and I really like the UI. I mainly use 3DSMax, and in Max you can easily create complex and dense forests + cover the ground with grass if you wish to. Max’s viewport displays the trees as “pyramids” ( just a cone with 5 faces). Grass is displayed as a square. Also, VRay only renders what the camera sees, so it doesn’t matter how many objects you scatter. All of this is done on my old notebook I bought for school. A dual core i5 7th gen and a geforce 940mx.

@Moove_Studio

2 жыл бұрын

I'm not 100% sure about particle systems, but I know for a fact that the array modifier doesn't use instances (which is pretty offensive IMO). Blenders "new" Geometry Nodes however has the option to scatter meshes as instances which is why you'll find a tonne of tutorials about it on KZread. I'd highly recommend going that route as you have a tonne of procedural control that you might now otherwise have with other solutions such as particle systems. I'm familiar with Maya's proxy system which is very stable and I love that you can easily specify which Geo to use as a proxy mesh in the viewport. I haven't been able to find an option like that in blender yet, which only gives you the option for e.g. wireframe or bounding boxes...(that said, I haven't actively searched for that option yet either, so I might be wrong). That said, blender doesn't use instancing in many situations where it COULD and where it would make sense (e.g. array modifier). Let's hope that these features are included in the future 🤘🏻 EDIT: just looked through the documentation and apparently the particle system DOES instance objects in place of each particle - which explains the good performance in this video even when increasing the particle amount.

Well, to me, proxies are kind of an incomplete system. Ideally, you can preview everything while you work, that way your creative decisions are well-informed. That's one of the reasons I think Clarisse IFX is so cool, because you can preview EVERYTHING in the viewport, at full-res. I wish Blender had a rendered viewport (at least the option), and obviously mesh/texture streaming would be KILLER.
