Mental Ray, Caustics issue

[noar]

I created a glass and 4 icecubes using xsi and subdivisions. Imported the models into softimage3D, put the icecubes in the glass and a spotlight on the set.

I applied caustics to the glass and icecubes equally. Now the glass creates a caustic effect as one would expect but the icecubes within the glass create soild shadows.

I expected the caustic effect to propagate through the glass and icecubes and hit the surface with a nice caustic pattern.

so what could i be doing wrong?

is there a depth level that i can modify in order for the caustic beam to cross more than one surface?

Thanks.

Bonjour KiFe,

Go in Matter > Preview > Setup
Increase the Ray Trace Depth to 10, then exit.

Go in Matter > Render > Options
In Ray Depth, put 5/5/10, then exit.

Make sure that your light casts raytraced shadows, if any.

Have you checked that all your pieces (glass and ice cubes) have Caustics properties, and they are set to be transmitters and receivers?

I don't want to sound haughty with these basic tips, I just check that everything is properly set

Hope this helps

yeah, ive got all my elements as receivers/transmitters... but ill try those raydepth values... mine were set lower than that so i think that may be it.

ill let you know if it works.
