Topic: single face painting

[archmelino]

Is possible to paint a single face (edge) of object?
For example if I have a cube (one material) and I want to paint with different materials any faces I have to go in Sketch up, explode the cube and pain any face with different color in Sketch up, than save in collada and so I can Work in Lumion for work with different material. Is not possible to do that in Lumion? Thank u

Hi archmelino, you have to apply separate materials to the faces of the cube in SketchUp if you want to be able to modify them individually in Lumion.

...in Sketch up, explode the cube and pain any face with different color...

I am not sure what you mean by "exploding a cube" in SketchUp. There's no "cube entity" that you could explode. You can explode groups or components for instance but if your cube is a group or component, you do not need to explode it but editing (double click) is enough. Now you can paint a face separately in the editing context.

It is not a too big issue however. Upon saving the Collada file again, you can easily reload it in Lumion (keeping all prior material settings intact).

I was mean: if I'have an object (for example a cube) that in Schetchp is all red, when I export to collada and import in Lumion is not possible to paint with different material any single face. I have to return in Sketchup, pain the faces and re-import to Lumion.

All right, this makes sense. And you are right: Lumion treats faces with the same material as (sort of) one entity so you can only handle them together (in fact, most render engines do). You will need to decide in SketchUp (or any other modelling application) what to handle differently and texture things accordingly.
