OK, tested out the MAT compatibility with RDNAs Old Wood stuff, and it works fine. My favorite mats came from some of the full versions I bought, but there were a couple from the OW expansion 1 pack that looked pretty nice. The desolation pack also has a burnt out looking bark, but it shows patterns too clearly in the when textured on this guy....drat! Technically, any bark texture that is seamless will work, as long as it isn't too different proportion-wise....I can always rescale the mapping, but I would need an example to work with. Let me know if you would like a copy (and can handle a 2meg zip file) If it is too big, I can chop it down using some optimization settings, however, that risks losing some of the detail in the branches and possibly some of the rounded shape of the trunk...I can also try and reduce the number of branches though what you see above is my favorite so far...it might not look quite as nice with any fewer.... IM me with your email if you want a copy of the file. When you are happy with it, I'll see about making it available under freestuff. eric
