I wanted to know if there is any more documentation regarding the render elements. I am keen to know more about the Light Select render element.
I have looked at the docs for 3d max and they contain a bit more information than the maya render elements docs but nothing on the above elements.
I search the forums but only found a post from quite a few months ago asking for more documentation on render elements and a post from Vlado about the Light Select render element when he was just implementing it. But not really detailed way of using it.
AFAIK, the RE_Light_Select let you extract the “direct” lighting contribution on a per-light basis. i.e. if you got a scene with a sphere and two lights, then the Beauty = RE_Light_Select one + RE_Light_Select_B + GI. Currently, the indirect lighting contribution cannot be isolated on a per-light basis. Actually, if you do a research on “light select” or multilight on all forums (not just the Maya ones), you should be able to find quite some discussions and requests regarding a Light_Select render element that can be used as Maxwell’s multi-light feature. Hope to see this coming in future releases of Vray.
To use it, simply create the RE_Light_Select (as many as you wish). The created RE_Light_Select will be shown in the outliner. Then drag the light(s) onto the RE_Light_Select you want it(them) to be associated with. Alternatively, you can associate the light(s) and RE_Light_Select through the set relationship editor. It’s pretty straight forward once you get a hang of it.
Btw, you can choose to only extract the diffuse or specular components of the RE_Light_Select.
Sorry to revive this thread on light select.
is suppose to only show the diffuse from the light? Could we also have the reflection.
I have a light on a side of a car, which doesn’t appear the lights on the car (which is made of chrome and glass) as it doesn’t have any diffuse.
