Blender version 4.0:
I have a simple hangar structure and I've used an environment map. All the faces use the "Hangar Interior" material except for the sandy floor which should use the "Hangar Floor" Material which is nothing but the duplicate of the interior material with some wavy 'sand' texture added to it.
Everything shows perfectly in the render view, but when I am baking both the materials (yes, I've ensured the same image texture is 'selected' for both material and the floor material is 'assigned' only to the floor face) the generated texture in UV Editor screen applies the Interior texture (which has smooth sand surface) to the floor face. Why is it happening?
