Refraction vectors Maya

[Mdelosrios]

Hey, so the sampler info node in Max has an output called Refraction Vectors... Is there a similar version in Maya?
I want to be able to output ST information to then distort an image in Nuke as if it was being refracted...

Besides from creating an image plane with a UV ramp, and refracting this, what's the best way to output refraction information?

Hey, so if you add a sampler info render element (not the same as maya's sampler info node), under render setup / render elements. There is a type you can choose refraction vector just like in max.

Hey man, thanks for the reely... what version of VRay are you using? I do not have that AOV in 3.4

[Morbid Angel]

Yeah its only recently been implemented. You would need nightly access and 3.57 from April 26th or later. Email support if you want to get nightlies login setup.

[Mdelosrios]

oh I am going to have to look through the nightlies... but that might be a rather complicated situation as a lot of what we have right now is based on our tools working for this specific version of vray...


No other way around?

But I will give it a try... do you have the exact version number so I can look for it in the nightlies section?

[Morbid Angel]

Yeah here it is: V-Ray for Maya version 3.57.01, revision 27412 from May 18 2017

[Mdelosrios]

Oh, I can't see that specific version of vray in the nightlies folder... On the folder for the 18 I can only see some vrayblender builds... going to email them then.

They have different branches of nightlies, you might be on a stable one.
