OptiScene 1.1 3D Tools 4.0 Community

Submitted by user Smorty; MIT; 2024-07-23

Adds a tool to combine MeshInstance3Ds into one MultiMeshInstance3D

Changes since last version:
- Added parent name and type indicator to figure out exactly which meshes will combine
- Added collision support for summarizing multiple Staticbodies into one (Watch out for non-uniform scaling of these Staticbodies though!)
- Added scaling support, including non-uniform scaling
- Improved console output for tracking down exactly what is happening during combination
- Instead of replacing the meshes, it just adds the MultiMeshInstance now, in case something goes wrong in the conversion
- Added seperators inbetween combination-options for more readable design
