Materials-only preview

When you convert textures without geometry, the viewport offers Sphere and Plane previews instead of a mesh. Geometry-only toggles (wireframe, scale figure, blobs, Outliner) are hidden.

Interaction with materials

• With the Materials tab active, click on an object to identify its materials.

• Use the paint-bucket Assign material tool, then click a mesh in the viewport to paint it. You can also assign from the Outliner.
