Hi there and thanks for your time!
Is it possible to use user data on lights? I know that you can on mesh lights, but I would need for an area light in my case. Cant get it to work, seems to work only on geometry. Thanks again!
For an area light, only the color is linkable (eg can have a shader linked to it)
What are you trying to do?
Hi there! Thanks for your time!
I've tried to do that with the file texture and an aimultiply node, but not a shader, will try that!
This is what I am trying to do:
We will have hundreds of those spots, the slider will control both the material's emission and the light intensity, the sliders will be controlled both manually and through scripts. I could do it with operators and make a script that duplicates the standin while rewriting the operators but I was trying to avoid that.
Thanks again!
Yeah, it does not work, it works in the scene itself, but once exported to a standin, it wont work, just meshes or mesh light.
Is it okay if you just use the aiUtility white flat color and arnold indirect Rays on for indirect lighting illumination !!!!
Hi, thanks for the Idea! unfortunatelly no, and would bem more efficient to use mesh light as It Works, but I need the spread attribute of the area light.
