View Full Version : Dialectric node problem

06-22-2007, 08:09 AM
Hi guys,
I just render this scene with fprime 3.01 i was testing the dialectric node. And it gives me a nice result, but even if double sided material is on, i still don't see the inside of the glasses. Also the refraction look strange. Does anybody know what the problem is? :(

Thank you

first things first, check your raytrace options in the render globals and also check the recursion limit is at least 8. does seem like something is missing.

Thanks Colkai, the raytrace options are on as well as refraction, but recursion limit is at 4. i'll change it to 8. I also model a third glass with a double skin to see what happen. I'll see if i can post somethig o got to get back to work dull!!!!!:(

Ok i've got the double sided object, i just modeled a solid glass, solve the problem for the reflections. BUT NO SHADOWS....what the hek?!!!!!, i'm using an area light, if i change it for a spot or point light, the glasses will cast shadows....hmmm!!!!

Two questions, Do you have the dielectric plugged into mixer with a standard air surface and Polyside info switch? and do you have raytrace shadows on?

Yes to both questions dog her is the node tree...

How big is your area light? Maybe it's to big to cause visible shadows?
