Short description of error
Blender crash on cycles render preview mode when changing frame, or playing and stopping animation with volume objects.

Exact steps for others to reproduce the error

  1. Open file
  2. Bake smoke domain
  3. Switch to rendered shading
  4. Play and stop a few times

Bug in 2.92A

@Brecht Van Lommel (brecht), I am going to test to see if D9340: Fix T81893: Blender crashes when using Gas Fluid Domain in Cycles fixes the crash.

Evan Wilson (EAW) triaged this task as High priority.Oct 26 2020, 3:49 PM

Can we have a general skip playback rendering strategy to avoid those crashes about heavy stuff to render on machines that are not build to do it ?
We could have a black screen with a warning : "too heavy render to allow playback" and just render frame when playback is stopped.

Anyways, playback in Solid mode is more satisfying to have an idea of how smoke animation looks like.

That case is so far from a real practice. Just because it is a crash, it has an higher priority than other real issues.

On second thought, while both of these reports produce the same stack trace for me, and both are fixed by the one line change diff D9340 applied on top of current master, I will again separate them (as @Richard Antalik (ISS) asked to be done in T82016: Crash on Cycles render preview when using Volume objects) for easier testing. This report involves a mesh object domain created by quick smoke, and in my testing it can sometimes take starting and stopping the playback several times before it crashes. T81718: Volume Object crash on frame change involves a volume object that crashes for me on a single frame change.

Sorry about the noise.

@ronan ducluzeau (zeauro) from your comment I take it that you have tested this report's file and it didn't crash for you. What are your system specs? So far (although I could be wrong) these reports only involve Intel CPUs and NVIDIA GPU cards. I wonder if AMD CPUs for example aren't affected. If you could, please also test T81718 and report your findings there as well.

Evan Wilson (EAW) renamed this task from Crash on Cycles render preview playing&stopping animation when using Volume objects to Crash on Cycles render preview playing & stopping animation when using Quick Smoke.Oct 27 2020, 5:11 PM
