Note: OptiX takes more GPU memory so if you get 'Out of GPU memory' use CUDA instead
@karlpelzer94858 күн бұрын
You can also run out of GPU memory if you have enabled rendering in the viewport at the same time while rendering the final image. When you have this combination AND you render an animation, in addition performance will drop significantly.

According to my experience tiling is also important on big size renders. Let's say you are taking an 8K render with bunch of geometry and textures in the scene, in this case if you dont use tiling the whole frame rendered at once is much slower than multi tile rendering and it might result in crash or not responding status. Leaving it at 2048 with tiling enabled usually works good for me.

@Benn2511 күн бұрын
Thanks for the breakdown. You skipped very fast on the film section, but I realize that you changed the default "blackmann-Harris" to Gaussian, is there a reason for this? BH should work pretty much like Gaussian, but with a little bit more respect for high frequency noise and patterns, in other words, at least as far as I understand, BH should be better (true or not??). also, the Width of the filter is quite important. You let the default 1.5px, it works well, but personally I decrease this a bit to 1.25 or even 1px when I have very fine details to keep them alive, then I add a soften filter in compositor anyway after if needed. this setting is here to prevent aliasing, and it is worth messing up with it sometimes. the guys making pixel art decrease it all the way down and use the box type to keep line completely aliased and pixelly (I never tried though). other point to be aware : the noise threshold should be avoided as much as possible in animation. I extensively tested this, and even with crazy low values, I always end up with area with very noticeable temporal noise. for still, it is very good though. For what I have tested, Fast GI approx will result in about 10% render time boost with 3 steps, and another 10% boost with 2. Pretty good, and almost no change, and interresting bonus : better AO for using in compositor if needed (at least for what I found). Using volumetric will at least almost double your render time, even if you use an emissive shader as volume. probably heavily graphic card dependant, but for me, deactivating rendering tiles is always faster that having it ON. You may need a lot of graphic card memory if you render big though (I have 16GB, never had any memory problem)

regarding tiles, gpu is faster with big tiles, cpu is faster with small tiles. if you do a lot of rendering, like a mult animation, maybe it is a good reason to test performance with different tile sizes
@DECODEDVFX6 күн бұрын
That used to be true, but it isn't really the case since cycles X was released. Before I made this video I tested various tile sizes on CPU. It was always faster to use the default tile size of 2048 when rendering at 1080p. A tile size of 250 was a few seconds slower. A tile size of 50 added an additional minute to the render time per frame.

Hmmm. Lower shutter speed "decreases motion blur"? I mean. I don't know a lot about blender or rendering. But in photography lower shutter speed would increase motion blur, not reduce it, higher shutter speed would decrease motion blur but some how in Blender's render settings it's the opposite? That seems weird to me.

@@DECODEDVFX nowhere. just sick of getting recommended beginner blender videos, because that's literally all there is. Also, my main complaint is that there is basically no reason to make a "how to render faster in cycles" if you're just gonna make a compilation of basic tips. I could recite the whole video by memory at the first watch, beacuse this same video has been made over and over again over the years by every blender youtuber. This video adds no value. Would be interesting to see maybe a "definitive guide to faster rendering, scene optimization and desnoising, both inside and outside blender" video. Showing stuff like: - baking lights to textures for rough static objects/materials - using render layers, holdouts etc. with different sample values for different parts of the scene - temporal denoising techniques (even using Davinci Resolve's Temporal NR on top of denoised renders to reduce artifacts - compositing EEVEE volumetrics on top of cycles renders, or faking volumetrics in the compositor - using the best AI upscalers and frame interpolation to render (potentially) in a quarter of the time - analyzing scene complexity, baking procedural materials to textures, using the correct shaders etc And these are only a few thing i can come up with on the spot right now. That would be actually useful to intermediates and beginners alike, and actually be original and valuable information
