Mapping: different materials to faces

Hi everybody!

How to assign different materials to faces of the same object?

And what if I have two objects made by the same material but I want to assign a different orientation to surfaces?

Hi Gabbiano

You need to add the materials in your modeling program.

Jorgensen is right.

Lumion will combine surfaces that share the same material in the 3D modelling application, so as he says, simply add unique materials to each surface prior to exporting the model.

Thanks!

Where can I find any other info about mapping in Lumion?

1) Can you describe what are you trying to achieve?

2) And which 3D modelling application(s) are you using?

So, I'm using Google SketchUp. I have some objects of the same type (some chairs) I need to render using different materials and the same material mapped in different ways.

What's the best way to map materials in Lumion?

There are two texture mapping modes in Lumion: You can either use the imported texture coordinates or Lumion's automatic texture mapping system.

The way you switch between these modes is via the Scale slider in the Standard material. Scale = 0 means that the imported texture coordinates are used. Scale > 0 means that the automatic texture mapping system is used (This is explained when you open a Standard material, and place the mouse cursor above the blue question mark button in the lower right corner).

To place textures in Lumion using the automatic texture mapping system, set the Scale slider to the desired value, then adjust Placing -> Heading/Pitch/Bank/X/Y/Z sliders.

Just bear in mind that the automatic texture mapping system does not work well in all situations, especially on organic shapes.
