Heh a cake shader eh ??? Hmmm not a lot of call for that one but you never know...
I have a render out. I made it do the full bung in the middle of the Mistys and then do some cheap bypass off that area so no snow in the north etc - just enough to tell me whether this is worth it or not. I think it is looking at it as we have Fangorn and Lorien full now and no duff region in Mirkwood. The new code makes getting the Veg right much easier than before. Veg growth before was a criminally sporadic process. There is some scope that this new veg change might help with rivers too... in that bizarre kind of way GTS works.
Anyway - is this better ?
