Light select pass without primary lighting?

[SonyBoy]

Is there a way to have a light NOT contribute to primary lighting, but still output a light select element from it?

no, all elements are derived from primary rgb buffer.

You could add a light select with just the direct illumination, and then subtract it from the rgb or the full light select.

Vlado do you mean in post? Thanks.

You should be able to do this in post with a simple substract (minus) operation.
