G'day

I'll post a testscene and rendering i did to test dielectrics and see what it would look like on some kinda simple and quite ugly vase type of shape.
Without getting too boring here comes the screenshot and the rendering.

Maxwell rendering:

C4D screenshot:

Glass shader settings:
Transmittance color: 95, 186, 197
Absorbance: 0
Refraction index: 1,786
Abbe: 300
U roughness: 0
V roughness: 0

Cinema4D scenefile:
http://hem.bredband.net/magron/Vase_Max ... Test_1.c4d

Total rendertime for this scene was 32 hours 4 minutes and 56 seconds and it reached sampling level 15,39 which i thought weren't bad at all and the end result is quite clean. This is also a unprocessed rendering, no noisereduction. Only the logotype and text was added to it.

Hope this helps with something for someone, if not then o well.. no big loss :)

For a P3 700mhz, I guess it's alright :)

The Rhino Plugin doesn't allow a greater value than 200 for the Abbe, is 300 a typo :? or different from plugin to plugin :?:

I know it looks odd with Abbe 300 but no it's not a typo, it's the actual value i used and it worked. It was a test to override the maximum Abbe of 200 to see if i would get any type of errors but it seems that i didn't which is good. :)
However Abbe 200 should work just as well, it should't make a difference if that's the limit set in the Rhino plugin.

in max i can't specify any value greater than 200 either. i guess that it wouldn't make any difference anyway, abbe 120 is usually more than enough to get a clean dispersion free glass.

That IOR is just a random number i put in, nothing special. I don't even know what type of material it would look like heh :/ perhaps i should have looked it up first. Sorry
