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.

Just because milk is white doesn't mean that clouds are made of milk.

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