Yves :
I guess it's the french magazine "Studio Multimedia" (the worse 3D mag in the world don't you think ? but the CD rom is OK, there is always one or two useful freeware/shareware.)

Alekssander :

In Metasequoia Le you can apply texture by using either :

• the "attach material to face" tool
  and / or
• the "paint mapping bitmap" tool

First you have to open the material panel (Ctrl+M). Click on "new" to create a fresh material and double click on it to open the material properties window.
There you can edit the material (color, specular, texture mapping, bump mapping, etc...). Afterwards pick the "fill" tool ("attach material to face") and "paint" the texture on each polygon of the model.

The "brush" toll ("paint mapping bitmap") works in similar ways as Body Paint, Zbrush, etc... it allows you to use brushes to paint directly on the model.

There is also UV mapping but I don't know exactly how it works...

I think that Metasequoia is a nice modeler but concerning material and textures you should use another software (VUE ?).

I always save my Metasequoia models in Truespace COB format, VUE 4 can read this format.
If I need UV mapping, I convert these COB files in OBJ files with Crossroads (free 3D file converter) and load them in the UVmapper made by Stephen Cox (it's also free, get it at : www.uvmapper.com).
