Merging Actors with negative scale, brakes materials. Is there any way around this, has this been already reported? The newest hotfix, does not mention this.
anyone? The negative scale changes the material ID of the actor, while all other actors are correct.
This is also happening to me. Looking into the issue lead me to the issue being related to the bIsMirrored block within the TransformRawMeshVertexData function in MeshMergeHelpers.cpp, but I’m not sure as to the proper fix. The intent appears to be to properly flip the render direction of the surfaces to properly match the transformation. Looking at the difference between 4.17’s section of the same variety, it looks like it would be properly functional and I’m not exactly certain why it was changed.
