Even I learn something new every day, cheers

@tig said: Add the Image inside a new empty group group.entities rather than the model... Manipulate the Image size etc as desired Explode the Image. You now have a face inside the group.entities Find the face in the entities - there's only one. Leave the face.material as it is [i.e. the image now made into a texture]. Make face.back_material=nil to use the 'default back material' or say use face.back_material="Black" to make it 'black'... That did it! Genius, TIG!!

@jrudd said: Any idea what the make_pano_pm.rb file does? @unknownuser said: Creates a set of photo matched pages given a series of panoramic images. Also creates a box (using create_box) which makes it easier to start sketching over top of the images. In the last edition of CatchUp (#5), was a article entitled: "INTERIOR DESIGN how to make a look around background" (midway thru the zine, just after "MAYOR MIKE’S GADGETS" section.) http://78.47.159.221/CatchUp_5_2011_10.pdf

Black tape on the check engine light will probably be just fine. Maybe. I hope. I don't find that I get reversed faces all that often when I work. And fixing them as I go isn't that big of a problem. I just right click on a properly oriented face and choose Orient Faces. I do see if frequently in models by other folks who start with flat surfaces divided into smaller faces and then use Push/Pull on them. Of course in those cases, while it looks like the faces are reversed, SketchUp is doing the correct thing if you look from the other side. As was already mentions, internal faces can cause problems but those should probably be removed anyway.

I have the standard DLL that exports to XSI. So I just File > Export > 3D Model.. and choose XSI and press Export. I read this XSI file into my app. The coords I've given you are from OBJ so its easier to understand (more readable) Would this be the reason for me getting bad data. Does someone have a simple C++/Ruby script that exports all models, their textures and vertices/UV coordinates? .. I can use this alternatively.
