Problem with glass ..PLEASE HELP!

[dufalins]

Hey everybody!

So...thats my first try with Corona, and i've found a problem that i can't kill!

The glasses on the table... i dont know why they are with those brutal highlights (if you look in the mirror, they are not that way)...
something in the refraction maybe? (because of the alpha channel)

I'm pretty lost....

That's quite strange indeed... Don't they have by any chance inverted normals?

[dufalins]

Rawalanche... no way....i've already made a test with inverted normals...same thing.
=(

Not sure but it looks like your black in diffuse colour is not really black.
Also, can you post your glass geometry or try this material on a different object then region-select and render it?

[Ondra]

does changing the camera angle help? From the alpha channel it looks like you just caught the windows directly in the total internal refraction

Maru,

Tested with full black on difuse...same problem.
Will try to remake the model (thats a very old one)...and will make a test with another objetc on that area with the same material.

Keymaster,

unfornutely the angle was asked by the client (they ask for a thousand cameras, and ALWAYS chose the boring one).
Agree with you about the alpha.... I've mada a test with the original material converted from VRay...same problem. But i've had nothing with the vray render.



Thank you so much for the help!!! Will make some tests here and keep you updated!

Damn, second time I thought I'm so smart. :P

I asked about geometry because it looks a bit like the light gets refracted in a strange way (as if the glass was a thick solid object, or is there some fluid inside?), this could suggest uncapped geometry.

[dufalins]

Maru,

as i can see on other posts here in this forum ...you ARE fucking smart! \o/

Its a solid geometry, with no liquid inside. I'll review the model itself.... it's probably tooo thick.

Will make some changes on another scene for a cliente, and after that will break my skull on that issue again!

Thank you so much!

PROBLEM SOLVED!!!

feel so dumb now! hahahahaha

he problem was the mirror (behind the glasses). The shader was just a mess...blends and some stuff i really cant understand why.

Thanks for the support and attention!

Cheers!
