I was forced to update the project to 5.4, since in this version the VDB and simulations look much better, but I ran into problems. Sometimes the engine crashes after turning on the simulation, sometimes when trying to render a sequence. Also, during rendering, the UE may simply freeze without rendering a single frame; a crash does not occur, but rendering does not continue. Often the message “GPUSkinCache.cpp” is displayed. I heard this is related to the use of lumen, but I cannot refuse it.
Greetings @Slumsnake
I saw a thread on something similar to this recently where they were having crashes and the GPUSkinCache was popping up. Take a peek here Editor crash with "GPUSkinCache.cpp" - I hope this helps! If not post back and we can check some other areas.

The skin cache issue happened in 5.3 already though. Short answer: It only crashes with “support hardware raytracing enabled” and when using a component using “lead pose component” (like metahuman)

Yes it was skin cache, not only ray tracing. I saw this post before and turned off ray tracing, but that in itself didn’t help. I uncheck the “support skin cache” checkbox and it works! Since ray tracing requires skin cache to be enabled, it will also have to be disabled. But everything will work even if the stage is full of modular characters with set leader poses and rigs (metahuman hasn’t checked it yet). In any case, thanks for the tip!
Awesome! I’m glad that you were able to get it resolved!
