viewport weird shading problem

[hoseinasadi]

after i assigned materials to walls , they turned black and i have no control over the texture in viewport unless i hit render everytime id want to modify them which is not logical at all. im using 3ds max 2010 64bit. is this a software bug ? cant it be fixed?

"... The viewport updates to show the sub-material assigned to the selected faces.

 

The material ID values in the Multi/Sub-Object material and the material ID numbers in the Select Face rollout correspond. If you set the ID to a number that doesn't correspond to a material contained in the Multi/Sub-Object material, the faces render as black."

 

Maybe that.

Try shaded mode instead of Flat.

Try shaded mode instead of Flat.

 

no difference.

Maybe the 'Normal' is flipped on the wall or perhaps missing uv map.
