Regards everybody ... I have a little question, once modelated an object in sketchup ... How can i texture my object like this picture ? when i export my object from sketchup, textures export one by one ....
You can try to create that kind of texture sheet in an image editing software such as Photoshop or GIMP and use that sheet in SketchUp.
Some other modeling programs have features to bake the textures into one sheet but SketchUp doesn't.
Or.. you can use MCX and use the material editor to optimize your textures and draw call batch them as well.
You can also use your various individual (e.g. 128x128) textures and put them together in one big texture (2048x2048) and then map them again in Sketchup.
