Thanks to all of you!
Actually the tree has been painted with a few dead tree textures,but
it's more like a theatre prop so you can see some detail from a distance.
As far as i know it is currently not possible to texture it with an additional
power fractal inside TG or simply apply a photo texture,because the UV
seams become visible(see attachment please).But of course one could
change the overall color and the reflection tint.
For comparison i've attached an untextured version also.
And yes,i'm going to share it,if you guys want it.
What kind of variations would you like?
