Hi Folks

I'm having some problems with a two-sided texture. The scene is of a guy on a BMX in front of some office blocks, and the objective is to have each window pane on the office buildings rotate consecutively (like a departures board) to reveal some graffiti on the other side.

What I've done:

Macthmoved the camera and built geometry for the office blocks. Projected my background plate onto this geometry and baked the texture to an image sequence. Setup a two-sided shader based on normals with the original plate windows (image sequence) set to false and a graffiti'd counter-parts set to true. Seperated each pane and animated to rotate 180 about Y in a cascading fashion.

Problem:

So here's my flip-side texture:

But as you can see from this image - each window is horizontaly flipped (note the lower right splodge of paint)

Can you help me out? I've tried mirroring in the texture placement attributes but it has no effect. I was hoping there might be some way of doing this without making a duplicate of each pane.

Any pointers would be greatly appreciated.

Cheers
George
