Too bad FPrime doesn't do caustics.

Oh but it does (sort of)! This thread (http://vbulletin.newtek.com/showthread.php?s=&threadid=21045) shows how silverlw (http://vbulletin.newtek.com/member.php?s=&action=getinfo&userid=23900) has figured out a slow way to do caustics with FPrime. You turn on 3-bounce MC radiosity, crank up the specularity, and let it cook out.

The results can be pretty nice.

Thanks !! I will read it all.

Caustics is really great when working with glass.

I still wonder....should the air polys also be doublesided ?

Nothing should have the doublesided button enabled when doing glas but there must be double GEOMETRY when doing glas in LW.
There is plenty of tutorials for how to do proper glas in lw and how to assign materials for glas and airpolys.

FPrime also takes so long to render ??? But I though FPrime is a super fast rendering engine...can anyone tell me a bit...thanks:confused:

"Super Fast"

It is. For certain things. Radiosity in particular. A box on a checker board floor...? Dog slow. Comparatively speaking, of course.


;)


I've actually SEEN many of my old attempted radiosity tests completed with FPrime where I would never (hell, had stopped) trying to do it with Lw's Radiosity.
