I assume bugs are expected at this point in time, so i am genuinely curious if Epic is interested in bugs we find, and if so how should we proceed to report them?
While testing ue5-main earlier I found out a bug related to this recent code change:
https://github.com/EpicGames/UnrealEngine/blob/bc4d2ea3803c0059ed8e540fb17d622e68eb2a03/Engine/Source/Runtime/Renderer/Private/GPUScene.cpp#L1293
After adding instances to a HISM then clearing them up, this piece of code ends up reading uninitialized PrimitiveInstances , relying on their non defined Flags to process the loop and sometimes crash.
100% reproductible, add instances to any HISM, then clear instances and crash, doesn’t seem to affect standard ISM.
Broke my planet vegetation, kinda hard to miss ! ^^
