Title: Glass Material Problem
Post by: Ragnar on 2018-04-03, 11:01:05
Hi, I have a problem with glass material in my scene. When camera is looking trough shower cabin glass pan is changing  to mirror effect. I can't even see object that I have put behind shower cabin. Glass material Reflect: IOR - 1.44; Gloss - 1, Refract: IOR - 1.1 (same effect with IOR - 1.44), Gloss - 1.

Cheers,

This looks normal. Glass behaves this way when you look at it from angle.

Yes, it's what IOR is all about :) What you can do to make a non-realistic material that avoids this is raise the IOR to an extreme level (10, 20 or higher say) - this will make the material equally "super-reflective" at all angles. Then you can reduce the Reflection color to reduce the strength of the reflection to make it only slightly reflective. That way it will keep the same "slightly reflective" look at any angle. But, as noted, that would not be what glass does in the real world :)

Glas, really like that? When I look at the window, I dont't see reflections...I have curtains.
But I believe you!

Yep, glass is like that - the steeper an angle you look at it from, the more you see the reflection and the less you see through it (same with any reflective materials, you can see it on cars especially, where surfaces facing you are not so reflective, but at an angle they reflect the sky so much it drowns out the color of the car).

I am trying to remember when was the last time I've seen a glass car...
... oh, wait! Never!

I have the patent! Wait til I unveil the first model!

I just noticed the car ;)

Dang it and I told them to be careful that the first test model wasn't leaked!

Wouldn't do that. No airbags, Vampire woman.(drives at night+no reflection, like shower glass)

the steeper an angle

I don't have angles, it's a window!(with curtains)

Note for self: never ask for help in C4D corner.

Awww, sure you can.
The only prerequisites are to have seen the outside world at least once and knowing what the values in the materials mean before complaining that they don't comply with your worldview.

I have no problem with people being ignorant of some things. We all had to start somewhere.

Self-declared experts on everything refusing help for pages, creating bug threads for perfectly fine working things that just don't go the way they expect them to or similar ridiculous things.(that have happened way too often)

Well, for those cases I wouldn't expect much...

..hmmm @Eddoron: these Curtains. Are they on the inside or the outside of your shower-glass?

;)

curtains outside of the glass? MADNESS!

Thx guys for help. I changed few things in my scene. And everything works just fine. Sometimes people want realistic scene with unrealistic physics. And then the maraton begins.

Cheers

Glad to hear you got it sorted. ;)
