I use VUE 9.5. How do I make different textures on different sides of an object, f.ex a cube. When I try now the textures wrap itself on all surfaces of the cube!

Vue's material handling is very basic and object based, so unless predefined mat zones are present, it treats every object as a single material, hence the results you are seeing.

You would really need to map the cube in an external program or at a minimum, assign material zones to each side, though this too would need to happen in an external app. Alternatively, you could rebuild the cube using six thin cube panels right in Vue and then apply the materials of your choosing to each individual panel - I use this trick all the time as it's faster than going into another app for simple objects.

Thanks for your answer, yes I do models by myself in Inventor 2012, like you say

I can define separate faces (solids) for places where I want to have uniqe textures. Maybe this is the easiest way to do, unless I learn to use 3DS max :-)

IronHorse61, If your OBJ export into Vue has some info on material zones, you can then select the object in Vue's browser and then click on the down arrow in the botom left corner of its material preview to choose which material of the six you want to edit.  You'll see that part of the object highlighted in the scene window if you have the display set that way.

Hopefully the material names are unique.  If not, you can still rename the materials inside the material editor.  That's what I do.  I use Hexagon and it can be a pain sometimes to get it do decide on material names or domain names or whatever.  It creates names on it own that it doesn't reference again and you can remove unless you open the file in NotePad or something and start the cutting.  That's why I just model in it and texture elsewhere.
