Great program! Questions about my first model.

Hi Rado, I'm glad that you are enjoying using MoI! Since MoI has a lot different type of modeling mechanism than SketchUp, they can make a pretty nice pair to use them together for different types of models.

re: Texturing problem - normally with most polygon modeling and rendering programs unchecking "weld" on export would be the way to make things appear as different groups, just like Jonah mentions above.

That creates a mesh where polygons share a common point only within a single surface of the original model, and have individual points (stacked up on the same location though) along the boundary edges. See here: http://moi3d.com/1.0/docs/moi_command_reference10.htm#meshdialog under the "Weld vertices along edges" option for some more details and a more visual explanation of this.

But this is dependent on the polygon program to analyze the connections between polygons in order to form them into different types of groups.

It appears that SketchUp will not do that kind of analysis unfortunately. So the "normal" method for separating a polygon mesh out into different chunks doesn't seem to work for you in this case.

However, I think that there is a solution for you - export to OBJ format, and then use the SeparateOBJ.exe program that I wrote, you can grab it here:
http://moi3d.com/wiki/Resources#SeparateOBJ_editor

That will edit the OBJ file and do that different regions of a mesh are broken into completely separate labeled "objects" within the OBJ file. Hopefully the OBJ importer for Sketchup that you are using will bring in different objects in the OBJ file as different grouped components or something.

If you export from MoI with welding turned on, then SeparateOBJ will only break objects along sharp creases into different objects - to get a fillet as a separate object export with welding turned off.

Let me know if that doesn't seem to work and I can figure out some other method.

Hope this helps!
