ssh, first I just wanted to say thanks for a great shader, I recently used it for the Houdini/Mixamo competition at the POlycount site. I did run into a problem though. I noticed that if I give a light a category name, and then assign that name to the hair asset's render props (for light/shadow/etc), the hair comes out as a matte, the shader doesn't seem to get run or used. It only seems to work with lights that have no category name. Is that to be expected, or would there be something else going on that would cause this? The hair asset is configured to use your shader, latest version, using H12.1.

Do not know about the default fur.

In my shader they are used for the purposes of light linking.

So you can choose which lights are illuminating hair and which are not.

Categories are passed straight to illuminance loop inside of shader.

For more information on this please refer to the docs:
