Default texture backside faces does not respond

[frv]

I am trying to take a misplaced texture from the backside of a face by aplying the default texture but nothing happens.
This annoying since I am making some sections were you can actually see the backside of some planes. There is an imagetexture applied to those that are there to stay unless I make a new face. That is a bit too much work in this case.

Anyone else had this problem in 7.1

Hi frv,

Is that part not grouped or inside a component by any chance? In this case, maybe that material is applied on group/component level. Try to paint the group/component also with the default material (this shouldn't affect any materials applied to the faces directly "inside").
