How can I remove an assigned material on a poly face so I can correct it with the underneath material .

Scenario : . ——-

I have an object that has a blue material shader on ALL polys .

Now , I’m assisting SOME polys with an orange material . ( override the blue )
Then some of the blue and orange with white, let’s say .

l change my mind and want some back to blue .

How can I clear assigned materials of certain polygons , without deleting the material itself ?

I’m not sure if I’m explaining it right .

Thank you for your time and feedback .
Cheetah is truly an incredible software !

There should be a row of tags (little spheres) in the object browser for every material assigned to the object.
You can delete any of them and the material should disappear from the object.

The material itself in the material browser will not be affected.
 
OK, I had to do this a couple of times while I was working on my pickup truck. Here's a phenomenally ugly solution.

Select the polygons you want to clear. SPLIT them from their object. MOVE NOTHING. Clear the material from the split portion. Merge that portion back into its original object. Optimize, so that the two parts should join with watertight connections again.

I make no promises, but it saved my ass at least twice.
 
Ok, so we do need to take a closer look.
Every assigned material will have a shade selection in the material tag.

You need to keep that number, then in polygon mode choose the polygon selection with the same number in the object properties.

This selection contains all polygons with the given material.
You can now add or delete polygons from the selection.
Somehow there will be no instant material update in the viewer, the material will not follow the changes in selection.
But when you disable the material tag and enable it right again (top right checkbox in the first image above),
the selection change will register and your material assignment will update.

Hope that helps!
