Crash when slicing in UE5

[BARKEM-JC]

Ran into the issue others have with slicing a mesh with multiple UVs, so i tried it on one UV and still crashes but with a different error. Both UE5 & Dev4.5 branches have this issue.

Using the RMCStatic comp, copy from static mesh, set simple collision for simulate physics, simulate physics, slice, crash First exception using debugger, In SceneManagement: L"MeshBatchElement 0, Material 'Material', index range extends past index buffer bounds: Start 0, Count 42, Buffer Size 72, Buffer stride 2"

Any Progress?

RMCStatic comp, Copy static mesh to RM> Crash When Slicing. Same as what you asked. RMC(No Static), Copy static mesh to RM> Slice not working.

Both are simulated physics. (simple convex collision)

Closing as this is now a replaced version of the plugin so previous issues likely won't apply exactly. If you continue to have this issue on the new version, please feel free to reopen!

Thanks!
