Newbie Question - Are primitives different than models?

I understand Unity has primitive meshes, like cubes and spheres. Are these primitives any different than normal meshes. Is, say, a cube primitive different than an imported cube made in Blender?


If you Model cube you made in Blender is setup-ed like it suppose to be with a uv map for example, then there is not difference. Unity just added a nice collider for them that all the difference there is.

It’s basically the same thing it’s just a simple model with a couple added components, namely a basic material (white) and a physics collider (basic mesh that detects physics interactions like collisions and ray-tracing). If you were to import the blender cube mesh you could put on the default unity white shader and a box collider and you’d have the cube primitive.
