wait, why?  because you feel like you're being jumped on, or because you fixed the problem?    if it's the second, then no problem.   but if it's the first, then please understand that we've just never seen this problem before. if you can demonstrate it, we might understand it better.  just saying "exotic" doesn't say what the problem is.  unless you've diagnosed the problem on your own, the only solution for a developer is to switch to P4 style materials.  that isn't very viable as a long-term solution.

so please, if you're still experiencing the problem, let us see specifically what settings are creating which problems.
