Title: Another Glass Shader Issue
Post by: j meyer on January 21, 2015, 11:27:39 AM
Hi there,
trying the glass shader on a geometric structure I noticed something odd again.
So I set up some test objects and did test renders.

[attach=1]

Tried it with cylinders and unconnected plates,too.Always the same.

Here is another one with single sided square sheets.

[attach=2]

And on a Kleinbottle

[attach=3]

And yes,I've checked the normals for that one.
Also tried it with larger decay distances - up to 1e+010 - no joy.

I believe this is a ray depth limitation, hard-coded at present. If I recall correctly, Matt has mentioned the possibility of addressing it. But I may be horribly mangling all of this, so I'll try to have him check-in on this thread a little later. :D

Yes, I think it's the ray depth limit. I might be able to make this controllable in future.

Ray depth limit,aha,interesting and good to know about.
Controllable would be nice. :)
Thanks.
