On game play the 3rd Texture layer (multiplied ambient occlusion) is using the 1st texture channel when it should be using the AO channel.

In viewport Displays Fine, in game play it displays incorrectly.

this happens on 2.66 all revisions.

problem does not exist in 2.65a.

Does this report show anything different than all the various other multi-uv bug reports? In other words, I suspect this is a duplicate.

last issue reported multiple problems, 1 was fixed. I assure you this is a completely different bug as the included blend shows.

I think the problem is the same as of the attached file. This is a small simplified file though. Should help with debugging.

Any status on this?

Hi, there is a patch for this (see uvfix.diff). it should be applied on trunk only tomorrow though.
If you can however test the patch (with this and other test files) that would help

OK, i have applied the patch and rebuilt the Source, all channels working correctly.

Thanks.
