- Avoid saving blast global configuration unnecessarily every time the editor is opened.
- Fixed how to obtain the default physics material library. The relative path needs to be from the project folder, not the asset folder inside the project. It was also missing saving the physx configuration after a the default library is assigned to it.
- Fixed asset id for physics material asset 'assets/physics/surfacetypemateriallibrary.physmaterial'
