Photon emit radius


Recommended Posts

Could someone explain this function in the vray sun parameters to me. I looked at the vray help info, and it really doesn't explain to me what it is exactly for. Is it just for Caustics? Or does it have another function.


I did a search on here for photon emit radius before I asked this but didn't find anything.

thanks for any help

i think that this parameter is only considered when using photon mapping for GI.


however, a secondary use i have found is that this value changes the 'zoom' value of the sun when using the sun as a camera...


would be nice to know exactly what this parameter is for though
