Thanks Yossam, appreciate your offer to send rain... I'm using Speedtree Studio 7, I started with ST Architect then upgraded to Studio. The upgrade was only the difference in the retail pricing between the two. Studio offers the ability to hand draw trunks and branches, and quad poly output. Virtually everything I've done so far is within the capability of the Architect version, still looking to utilize Studio's additional features. Be nice if TG offered FBX, or even MDD file support to take advantage of the wind animation in ST, perhaps someday. I'm also messing with The Plant Factory demo, I suspect that TPF is capable of creating more exact foliage models, but so far it's more technical and hard to generate any sense of 'artistic flow' in the work process: a much steeper learning curve as well IMO.
Cyphr: Thanks! The Oak is my newest tree and I probably should have mixed in some other tree species to broaden the image palette, There are two leaf textures on the Oaks; one golden and the other a mix of green and gold (sorta of a progression look). I tried some samples with the mix favoring the green/gold, but it kinda crept away from my concept of the image. BTW, the god-rays were inspired by your splendid skies!
