Applying material to the 'other' side in grouped entities
-
hello all,
let's say i have a grouped object. this object has faces, which have front and back side; both of them are on default.
when i want to apply a material to this group, only the front faces get painted.
does anyone have an idea, why this might be happening? and how can i apply a material (preferably the same one) to the 'other' sides of the faces in group, without having to explode/edit the group?
thanks for any answer.

For v8 at least, it 'colors' the fronts and backs of a group's faces if they have the default material WHEN you paint the material onto the group itself, BUT applying the material to a face itself during a group-edit means the material is only applied it to the side of the face you 'paint' it onto, unless you have selected several faces beforehand...
When you apply a material onto a group the faces within it still actually maintain their 'default material' - it's just that they 'appear' with the group's material. Exploding the group then paints all defaulted faces with the group's material [fronts and backs]. -
It's also bad practice to be painting on back faces. In sketchup it doesn't matter, but if you export to other programs (rendering, usually) colored back-faces can be a problem. When that happens it's a pain to fix.
It might be a problem you never come across, but why do it? -
To me it also seems that when you apply a material to a group, both its front and back faces "look" painted. (In reality they aren't).

hi,
thanks for all the answers. i managed to get the result i wanted using this UV Toolkit plugin.
TIG: yes, i also thought that painting the group will apply the material to both front and back faces. sadly, this wasn't the case. maybe it could have been a problem with the geometry? my model was actually first generated by script in rhinoceros, and then i exported to 3DS to import it into sketchup for VRay rendering. also, this was a group of groups inside a component, so that my have also been the issue
dsarchs: yes, i read about that, but since i do all my renderings in vray directly from sketchup...
