chromatic aberration with VRay

[kosso_olli]

Also for Arnold - https://lentil.xyz/

Something like this is exactly what I need in V-Ray!

Anyone with camera shader experience in VRay? is CA possible with it?

This is what the docs for Lentil say regarding CA: "Lentil is a spectrally-plausible system. But since Arnold is an RGB renderer, we render at a single wavelength.

Note that one *could* render the same image 3 times with different wavelengths and combine them (1 for each channel) into an image with physically plausible chromatic aberration."

The changelog also show CA in action here: https://lentil.xyz/docs/changelog.html#2.4

the changelog linked shows axial chromatic aberration. I was rather referring to lateral ca, somewhat more commonly used in cgi (fringing intensifies from the center of frame outwards).

Well, in the examples the fringing is more intense on the edges, no?

yes, it does. but it is different type of aberration than for example this:

The type of CA shown in Lentil would be fine for me. Plus all the other nice features.
