Hi eric, let me know if you run into problems again.

You probably would want to use OBJ format for going into SimLab Composer, and colors should come through unless the stuff involving writing materials out to the OBJ file has been turned off. Those settings are under Options > Import/Export > OBJ options > "Write material assignments" and "Write .mtl file". You want to have both of those turned on (which is the default) for that stuff to go through.

Hi Michael ...

I am now having no trouble exporting to SimLab.

I do want to be able to add trees into my models and found a couple of pretty good libraries but they seem to be mostly available as .obj files.

I want to import an .obj file (the model of a tree) and, of course, cannot import it directly into MoI ... so I imported it into Rhino, exploded it, and saved it as a .3dm file ... then tried to open it in MoI. No luck. Is that because MoI won't import Rhino meshes?

Is there another way around this?

Or do you know of any landscape materials (trees and shrubs) available in .3dm format?

thanks,
eric
