About collision and occlusion shames for 3D meshes

Godot Version

Godot 4.7.1 on Linux Fedora

Question

Hello; is there a way to tell Godot : hey buddy, this is a mesh, use the same data for it , occlusion shape and collision shape

Please check Posting guidelines in #Help channel

For collisions you can select the MeshInstance3D node, press the Mesh button at the top of the 3D viewport and select Create Collision Shape...

For occluders you add an OccluderInstance3D node, select that node and press the Bake occluders button at the top of the 3D viewport.
