New Eevee Rendering Volumetrics much Slower than Legacy

Hi - small update - just tested this in 4.3 release with the same problem. I can't recreate in a fresh project so I am going to need some advice as to how to pin it down.

At this stage it might…

Is there a way to sample the process on linux like you can on a mac? Would that help? I could then start the issue off and sample the process and post it here.

All excellent questions.

As I write this I have started the process with the latest blender project. It does take a while for the memory to fill up and then crash and as things get close to…

New Eevee Rendering Volumetrics much Slower than Legacy

So here's my problem: I have a rather heavy scene I am trying to render. I have:

  • the principle foreground characters, 2 robots who are flying a trapeze, on their own viewer layer,
  • and the…

GPU Compositor Crashes when using Cycles (not Workbench / EEVEE) - Linux - Headless Node - Invalid Pointer

Hi so my issues seem similar to this. Setting the compositor to CPU is helping but I am still getting issues rendering:

Illegal address in cuMemFree_v2((CUdeviceptr)device_pointer) (intern/cycle…

GPU Compositor Crashes when using Cycles (not Workbench / EEVEE) - Linux - Headless Node - Invalid Pointer

I found my way here because I have been experiencing the same thing, latest Ubuntu, latest NVidia drivers, 64 GB RAM 16-core AMD, 4070Ti.

Changing to CPU compositing seemed to allow for…

Hi, I have recently come back to this problem. I have the new LTS 4.2.3 and Eevee is still problematic. I have a large scene I am rendering in Cycles, and holding all but the volume to render…

Hi, thanks for the report. Can you attach the simplified .blend file for comparison? Performance impact is likely expected due to ray tracing and a few newer features but there would be a way to…

4.2 eevee performance is atrocious

I think the problems are more than just compiling. I think there is a memory leak somewhere. The main advantage with Eevee is volumetrics and volumes are causing Eevee to render about 15 to 20…

Transform Nodes Cause Following Nodes to not Output

There are only 2 input nodes contributing to the scene. The other input nodes are alternative versions.

If you follow the instructions you get the bug - each time.

Anim: Only Insert Needed behavior changed (4.0 with Only Insert Needed enabled vs. 4.1 with Only Insert Needed > Manual enabled)

For auto key framing the function makes sense because you want to have as few keyframes as possible being inserted to prevent clutter. For manual key-framing there might be special situations…

Ah!

Actually - you can turn "only insert needed" off for both manual and auto - I thought it was a toggle.

That will resolve it.

This preference should not be turned on by default - I…

No this does not change anything - I have tried every permutation.

This is new in 4.1

Keyframes where a transform parameter has not changed cannot be inputted. So if you move an object along…
