Tiff Transparency Problem
-
Hi
Im a bit rusty on Vray. Its been awhile since Ive done a project with it. Im having trouble remembering how to do things. I imported a 3ds model which was mapped with tiff images to make into a proxie. The tiff images have transparency. When I try and make a reflection layer, reflections show up in the transparency areas. How do I fix this? I feel I should know this, but like I said its been awhile.

Hi there! Not sure what the problem is, but maybe you can try putting an alpha image of the leaf in the white channel of the fresnel reflections.
Your issue made me think about the fact that I never add reflection to a trasparent bitmap...

Thanks for your help
I had tried to put that inverted alpha into the Fresnel slots before. The result came out with a chrome like reflection. What I forgot was to lower the value of the reflection multiplier. I had to reduce it to 0.1. So you were right. -
you should put something similar to a bump map with a black background in the perpendicular slot of of fresnel map, that will give nice reflection effects on the leaf and no reflection to the transparent bits
