Hi guys, I posted this in another thread a while back, but thought I should update it here.
The only current solution is to disable Grass on the landscape (in brushify that’s MI_Landscape, untick all procedural grass tickboxes).
The reason for the crash is that MovieRenderQueue is attempting to render each blade of grass with the raytracer. Unfortunately even the tickboxes in the grass shader for disabling raytracing do not seem to have any effect on this. So for now it seems grass is broken with MovieRenderQueue.
This is tested on UE5 5.0.3.
I did submit a bug report and test project to epic back when this bug was first introduced, however I’ve not heard any response or ETA for a fix yet. I’ll try to submit it again soon.
