At the end of 2013 I did an animation for one of our projects with really simple tree (low LOD canopy).
I wanted to reuse this tree for a new project but somehow color tint is not working as it used to.
Before I used color tint with a gradient on the forest object and a fully transparent material with a fog color.
Back then I used forestpackpro 4.1.2 but now I'm using 4.2.2.
Max is version 2014 and Vray changed from 2.4 to 3.0.
When I try to reproduce the result, somehow the color tint has no effect on the fog color (see attachments).
Even when I apply a Forest Color map to the fog color slot in the vray material nothing happens.
Only when I put a Forest Color map to the diffuse slot and lessen the refraction I get some results but not the desired one....
Can someone please help?
