Thanks a lot!

I reproduced the and fixed it in the internal version. The problem was that whenever we prepared for voxelizing anything, we called FXSystem->PreInitViews, which switches the frame index, and the simluation doesn’t work properly because that should only be done once per frame.

To get it fixed before our next release, you can edit the file Engine/Source/Runtime/Renderer/Private/SceneVisibility.cpp and modify piece in PreVisibilityFrameSetup function:

if (Scene->FXSystem)
{
    Scene->FXSystem->PreInitViews();
}

Replace the condition with :

if (Scene->FXSystem && !Views[0].bIsVxgiVoxelization)

Thank you for the quick support!
