Fractures are not created for anything except the first submesh of a model

[ByteSz]

Noticed with models containing multiple materials (aka multiple submeshes making up the imported mesh), the plugin is only generating fractures for this first submesh found.

This can be noticed while previewing the fracture generation for any model that contains a mesh with multiple submeshes. Submesh count and visualization can be viewed in the project browser when inspecting a mesh, seen in the preview pane.
