yep i already knewed how to import 3ds (but thanks at all :P) but how can i re-size them right?
i only know how to size them step by step (size right side, size up, size down etc.) i want to size them like in blender (in one type and keep the geometryc)
Just put your cursor over the center of the Resizing gizmo, it should change colour. The same thing can be done with outer parts, but that will only resize in 2 directions, instead of all 3. Resizeing 1 way you just need to use the lines.
You need to go into the render options and look for CSG server iirc. If you go into Luma server you can change the light colour back to white. If you press 8 you can change the background colour as well.
Might be best to look through the render tutorial on wiki to find out about this.
