Hey guys
I'm doing a job in softimage at the moment, but would like to move it to houdini, just to learn a bit more.
The job is bubbles in liquid, so I need to render spheres with incidence (facing ratios ) driving reflections and refractions.
In mental ray this all renders lightning fast, but so far my mantra renders take forever.
I don't need any PBR effects, just good fast raytracing.
Is this something that is just super slow in mantra, or can you guys give me some advice on getting this to render quick?
Thanks allot
Gerbrand

Can you share how you did it now? Using Mantra surface shader?

to be honest, I didn't even get to a point where this worked the way I wanted it to work.
I'm running out of time on this, so I'll have to finish it in soft.
Here is my test scene.
It doesn't look anything like bubbles, but its still allot slower than I expect this kind of thing to be.
Thanks for looking.

What's your render time for this project ? It's so fast on my system , it's render time is somthing about 17 sec !
