Lighting Instrument Lens Color

[Darrell Henry]

So I modified a lighting fixture to have a lens that re-colored automatically to whatever color is in the color field of the instrument (using the helpful video on the VW site.

SS#1 shows the behavior working perfectly.

SS#2 show the result in the rendering I am working on. You will see a little bit of color on the edge, but no solid lens color.

I thought it had to do with ambient light level -- in SS#1 Ambient is on, in SS#2 it is not. However after further experimentation that is not the culprit.

Spotlight preferences are the same and RW Background is the same.

The texture that modifies the object has the color controlled by Object Attribute (which is controlled by the spotlight color field) and a Glow where the cast shadows box is unchecked. I tried unchecking the receive shadows box and that did not help either. I also tried increasing the glow to 400% which makes the halo brighter but does not fix the problem.

Anyone have any ideas on things I can try to change?

So I created a new viewport and now it is working....the only difference that I can tell is that I am NOT using a camera view to define the viewport. Now I am diving into the camera settings to figure out why it doesn't render correctly in the camera viewport.

Aggravating.

Darrell -

Did you cut a hole/well for your lens? If so, how far out from the "back" of that hole is your lens - and, how thick is your lens? I ask because I have found that objects that are very thin (.0001") and/or very close to other parallel surfaces sometimes appear to "clip" like in your #2 image.
