Warning Can’t save D:/Gamedev/UE4/Projects/Ex413P2/Content/Maps/LVL_TestEnv.umap: Graph is linked to external private object BodySetup /Game/Blueprint/BP_Test.BP_Test_C:ProceduralMesh_GEN_VARIABLE.BodySetup_0 (ProcMeshBodySetup)
This happen only with pure Blueprint, if i do it in C++ or i create a Blueprint based on a C++ class that contain a ProceduralMeshComponent all work fine.
Thank you for reporting this. I was able to reproduce this issue in 4.13 Preview 3 so I decided to give it a try on our latest internal version of 4.13 (closer to the full release version.) It seems that it was caught somewhere in QA and fixed as it isn’t happening in that version. As such, the fix for this should be coming with the full release of 4.13.
Had a mixup on my part, so this is actually occurring in our latest version but another user also reported this and another member caught it. Here’s the bug report for it. This is a major one so it should be fixed before 4.13 release.
