Now why would you do that?
This problem is rooted in the fact that SketchUp does not provide correct UV coordinates for distorted textures. Try rendering that scene in Podium (or another rendering engine) and you will see the same problem. AFAIK, the only renderer that supports rendering of distorted textures is Kerkythea.
The problem has nothing to do with projected textures. It has to do with 'distorted' textures. Distorted textures have been skewed by either being projected from a photomatch or by using the texture positioning tools (pushpins)
However, you are in luck because SkIndigo has had a workaround for this problem for a long time. All you do is right-click and select 'Explode Distorted Texture' from the SkIndigo UV menu. This will create a new material with an un-distorted version of the texture that will render properly.
I created this feature before the release of SU7. There is a native operation in SU7 called 'make unique texture' that does exactly the same thing. (I guess they liked my idea...)
One more thing:
When I tested your scene and I used the 'workaround' I mentioned, I may have found a new bug. So, even when you use the workaround, you might get an error message from Indigo. It is related to the material name. Before rendering, you might have to change the material names so that it includes only alpha-numeric characters. It's hard to explain why. I need to do some more testing.
