Steps to Reproduce
Hello,
We’re on UE 5.7.3.
When loading an open world map some people are getting this deadlock between the GameThread and the FLandscapeGrassWeightExporter_RenderThread.
We’re using PCG and Fast Geo.
This issue seem to have happened after we’ve activated runtime grass generation.
I’ve checked on the engine’s main branch, through the PCG, Landscape, Renderer and ComputeFramework sources, tried a few changes that could have been relevant but nothing helped.
Any help or advice would be appreciated.
Kind Regards,
Ludovic
