After 10 days of searching everywhere, I finally found out that Unreal Engine 5.3.2 crashes when I have a VDB far from the center. This only happens when Path Tracing is toggled on.
The coordinates for your reference:
(X=4813860.210258,Y=-5182445.981034,Z=-1332020.131163)
This is a flying object in space, and so many things are keyframed. I cannot simply bring everything to the center; even if I do, the flying object will quickly fly away far from the center again.
Any suggestions on what I should do? This scene used to work perfectly in UE 5.0.3!
Welcome back to the Unreal Engine Community forum. If you’re both having the same issue, I’d recommend try it in a different version to see if it occurs. If not, I’d try creating a new project in the version of UE you wish to use and migrate the files over then retest. Let me know if it resolves it. I’ll monitor the thread.
At first, this issue was resolved when I changed the engine version from 5.3 to 5.4 EA. For this, we had to redo all VDBs optimized for 5.4. As soon as I updated to 5.4.1 I found that the VDB in the far distance did not cause a crash, but instead became super pixilated when the camera is slightly far from the heterogeneous volume. This is the same project file.
Environment (both simultaneously):
If: VDB is located in distance
If: Camera is slightly far from the heterogeneous volume
P.S. I tried a variety of VDBs each in different levels and the issue remained persistent.
