SourceSection not filled in UE 5.4.4 => Crash #36

Open soma-web opened 2 months ago

soma-web commented 2 months ago

I added some Logs for debugging and do get the following Error: LogTemp: Error: SourceSection.FirstIndex + i >= SourceIndicesSize BP_PaintPanel_C_15

FurStaticData.cpp (Line 650 following)

        else
                {           
                    for (uint32 i = 0; i < SourceSection.NumTriangles * 3; ++i)
                    {
                        const uint32 SourceIndicesSize = SourceIndices.Num();
                        if((SourceSection.FirstIndex + i) >= SourceIndicesSize)
                        {
                            UE_LOG(LogTemp, Error, TEXT("SourceSection.FirstIndex + i >= SourceIndicesSize %s"), *Parent->GetName());
                            continue;
                        }
                        const uint32 IndicesSize = Indices.Num();
                        const uint32 Index = Idx++;
                        if(Index >= IndicesSize)
                        {
                            UE_LOG(LogTemp, Error, TEXT("Idx >= IndicesSize %s"), *Parent->GetName());
                            continue;
                        }
                        Indices[Index] = SourceIndices[SourceSection.FirstIndex + i] + VertexIndexOffset;
                    }
                }

Ok figured it out. Static mesh was not allowed to be accessed by the CPU, maybe try to catch that and print a error log?
