not a bug but a feature request, please make it possible to fracture mesh based on its material ID, I mean each material ID detected on a mesh can have differents fracture settings applied! it will make the workflow much more convenient and will save an incredible amout of time when using chaos destruction for large scale project! despite saving time, it will make already setup geometry/mesh of existing projects in development compatible and you don’t have to redivide, re arrange and setup meshes to get it running destruction conveniably.
