Refraction not affecting alpha?

[kriscabrera15]

hey guys working on a car that i am looking through the front glass all the way through the back, but for some reason my windshield material is not (refraction material) affecting my alpha. Alpha is pure white. i have properties affecting all channels and my ior at the moment is 1.0,depth is set to 8. if i use opacity it works, but if i use refraction it doesn't. any ideas?

Hi Kris,

Do you have strong reflections added to your windshield material?
What value you are using for the refractions glossiness ? There are some issues with "Affect all channels" and glossy refractions.

Can you post a scene or a screenshot?

i figured it out it was a matte issue, i have the affect refractions on the geometry, unchecked that and am good. Noob mistake lol
