I have started to build my own custom library using different purchased or downloaded plants from evermotion and AutodeskSeek/Xfrog. I have noticed on a couple pieces that I have either random greyscale buckets (using Vray3.0 and Max 2014) or just an altogether "off" transparency map if I leave the default .tiffs in for the opacity.
I have attached a few images to show you what I am experiencing. Any advice would be much appreciated.
Thanks for your time!
1st image: Straight Render after applying the optimize material through Forest Pack
2nd image: Diffuse taken out and colors added to help distinguish geometry
3rd image: Diffuse put back in and a .png with alpha map put in the Refraction slot vs. .tif in the Opacity slot. You will notice in this one it's better but there still seems to be a gray scale anomaly in the scene. I have experienced this on more than one custom plant.
