I am using a fresnel material to illustrate a lenticular shift of color. This works fine and is light (I have thousands of objects and only need to understand how it’ll look).
Problem is that fresnel is omni directional - I only want it to shift from left to right not up and down.
I more upmarket version is to have a truly lenticular material, preferably redshift, that renders fast, but I can do with the simple fresnel let-to-right shift.
Thanks in advance for any advice you give.
