My glass is Dark...

[jedt3d]

I've tried to learn KRay 1.7OB2. With my scene setting it's work ok when render via FPrime but got some problem with KRay. The glass is dark.

Material setting. (FYI: BSDF shader isn't affacted much after tried to disable/enable it)





Render from FPrime 3.01


Render from KRay 1.7OB2


What can I do with KRay setting or have to set my material ?

Hi,
Shaders wont work with fprim and Kray so you can kick it out.
Try setting diffuse and secularity to 0%. Glass does not really have and diffuse reflection and Kray does not like Specularity, its a fake effect anyway and raytracing it won´t take long.
Do you have all raytracing flags turned on in the global render settings?

and turn off doublesided, kray does calculate without airpolygons or any other stuff like that, just make glass volume and geometry is ready for the right refraction.

Hey guys, that's my false and my embarrassment.

I've not turn on Raytrace for reflection/refraction

How can I forgot the simple things like this haha

well but thank you for suggestion too. It's help me understand it more.

Why do you have diffuse on your glass?

Hi, Capt.
I'm not sure about LW Mat, please suggest me too if I'm wrong.
I think if I want a dark glass, I've to reduce the diffuse down, like when I make a metallic material. I will use a low diffuse, and make it shinny and reflective.
Actually, I want a clear, a bit green glass when we see from some angle and shold be a bit dark glass too. I've no idea how can I do that. I'll try to post some experiment or some example soon.
Thanks for watching!

Glass should NEVER have any diffuse at all, unless it's fritted or sandblaster or something such. The shininess is completely unrelated to your diffuse setting.
