Summary
Since Unreal 5.8, I am experiencing GPU crashes when rendering Geometry Caches with Path Tracer.
I was able to replicate the crash in a simple scene and provide my observations below.
What Type of Bug are you experiencing?
Rendering (Graphics / Niagara)
Steps to Reproduce
Create a test Geometry cache with following features (I created it from Maya 2026 and exported as Alembic):
- multiple meshes with different materials
- a total triangle count > 250k
- flatten tracks
Create a level sequence at 25fps with the following spawnables:
- a skylight
- a geometry cache actor referencing the imported geometry cache
- a post process volume with infinite bounds and a bloom intensity to 0.0
In the MRQ, use a legacy Render Preset with the following options (other at default):
- exr sequence: multilayer checked
- Path Tracer renderer
- Anti-aliasing: spatial sample count = 800; override anti aliasing checked
- Color Output: Disable Tone Curve checked
- Game Overrides: Disable HLODs unchecked; Use High Quality Shadows unchecked
- Output: 1920x1080
Expected Result
This level sequence renders perfectly in Unreal 5.7.
Observed Result
The crash is realiable whenever the bloom intensity is set to 0.0.
Enabling the bloom ever so slightly (like to 0.001) does not make it crash.
Alternatively, I was able to render this level sequence using a lower spatial sample count (like 100). However, I need the 800 spatial sample count to get a converged image with no motion blur.
I was not able to pin point the issue precisely but I suspect a regression in the construction of the render pipeline.
For now, I have the workaround of setting the bloom intensity to a low value but I am afraid it is not very reliable.
Any suggestions or help in the inverstigation would be appreciated!
