Hi. I new to Vray for Maya. I'm currently using version 2.30.01 on Maya 2013 SP2.
I am lighting my object with a HDR Map, plug into the texture slot of a vray light dome.
The issue that I am having is that the Vray Light Dome's "invisible" check box works differently from what I am used to with an IBL on geometry type of solution. I guess what I looking for is more like turning off "primary visibility."
Otherwise, making the light dome invisible introduces the environment color into the reflections and refractions, default being black. I only want my HDR Map that I am using as a texture in the light dome to effect my render, but I still need an alpha channel, hence the need to make it invisible.
I know that I can do this by putting in my HDR map in the Environment overrides, but I would much prefer to do it with the vray light dome if possible. I like the look better using the light dome set to visible, but I need an alpha, and I trying to avoid having to render a separate matte pass, since I believe that Vray for Maya does not support contribution maps. Correct?
Thanks.
