I seem to be getting an error trying to load this IGM, anyone else having the same issues?
Are you using the latest version of Indigo (4.0.45)?
I wasn't but I have just updated it and still not working. I can open it using indigo directly (material edit) but I can't import it into sketchup
Can't help you with Skp things, maybe the exporter can't import Indigo 4 mats yet.
Try again now Danj.
