Hi guys I have a question. I´m really lost with this. I have a plastic material. But this plastic material has a roughness transmission. Like a silicone.
The thing is I need the alpha of this to work in photoshop. I need the alpha of the refraction with the roughness effect. But the alpha show me the entire object with no roughness. I´m working with Arnold 5.
I do not know which is the AOV to do this and how to use it in Photoshop.
Thanks a lot guys
What would you want that AOV to look like? Have the alpha only where there are "perfect refractive" pixels? Comping rough refractions isn't possible (as far as my knowledge goes)
There's currently no AOV or LPE that will give you an alpha for refraction. That's something we're looking to add soon.
I will try to be more specific. I will work with 3Ds Max Vray and you will see what I need from Arnold.
I made this example in 3Ds Max and Vray:
ca1.jpg
As you can see in that image (Ca1.jpg) I made 2 boxes and one of them is a glass with roughness in this case the name in Vray is Glossiness. And when a select to see the alpha channel I see this:
Well I need the exact channel in Arnold. I can´t believe this option it doesn´t exist.
When I try to do this in Arnold I only see all white in the alpha channel with no roughness trough the box.
Thanks guys!
Arnold 4 had a refraction opacity AOV, but there's no equivalent yet in Arnold 5.
