Material preview primitive metrics

General Feedback & Requests

After an hour of debugging my material (based on world position), I discovered that the preview primitives used in material preview window is in fact NOT the Standard 1 meter (100cm) primitives! They are in some other slightly larger scale..!!???

This makes it horrible to debug anything, as any sane person would expect them to be 100 cm.

Pretty sure the extents(bounds * 2.0) of the cube and plane have always been 256cm and the sphere has been 320cm (diameter). You can verify with the object bounds node * 2.0 → debug vector3.
