Hey -
I got the project you sent and after debugging in Visual Studio it appears that the crash consistently occurs in FlareSpacecraftComponent.cpp at line 165 (FLOGV(“LOD %d APPLY EffectMaterial %s”, LODIndex,*EffectMaterial->GetName());). Further, I realized that the crash occurs when EffectMaterial is equal to “MaterialInstanceDynamic”_34. I say this because it appears to run through this function multiple times with EffectMaterial having a different value each time (first _30, then _32, then crash at _34). The issue seems to be with whatever this value represents, however I can’t dig further as I am not sure where this value is coming from.
