View Full Version : segment shadows

07 July 2009, 10:14 PM
"The Shadow Method is set to Simple by default. Simple shadows are not compatible with volume effects such as fluids, volume fur, particles and volume shaders and therefore may not render shadow volume effects correctly. This mode requires support from the shadow shader, which must use the mi_trace_shadow_seg function to cast the next shadow ray segment."

what is this "mi_trace_shadow_seg" node? can segment shadows work without it?

I find setting the shadows algorithm to segmented in the mr Render Settings window works fine on fluids. I'm pretty sure that's just telling you that you can use Simple mode in a scene with fluids as long as you tie a mi_trace_shadow_seg to the lights that affect it, the above is simply a globalised version of this.
