Hi,
The crash appears to be caused by a mismatch in resource access modes for the VirtualTexture_PageTable. Specifically, the error indicates that the resource is in an external access mode and is valid for access with states like SRVCompute, SRVGraphicsPixel, and SRVGraphicsNonPixel. However, it is being used in a rendering pass (PageTableUpdate) with RTV (Render Target View) access, which is not compatible with its current access mode.
I’ve been digging a bit further and found a thread on the Unreal dev forums reporting a crash which looks very similar to this one (second crash in first post). According to that thread, the crash no longer occurs with 5.5.4. Unfortunately I could not find the specific commit that fixed it, so I’m not entirely sure what is causing the crash.
If your project is not on 5.5.4 yet, could you try upgrading to it?
Let me know if that works, if not we can investigate this further.
Thanks,
Sam
