Lightmask for trace()


Wolfwood

Recommended Posts

Is there anyway to a set a lightmask with trace()? Similar to that of diffuse() or specular. I'm raymarching inside of a illuminance loop and would like to fire off some rays with trace() but I want the traced shader to evaluate using only the current light.

Or something snazzy like,

trace(cv, of, af, P, D, "lightscope", getlightname());

Of course this wouldn't be needed if we had ray labels. :rolleyes:

:P
