Hi!

I'm simply trying to use a cops image to change my camera's background image (Arnold). First, I wanted to test it on a uvquickshade sop to make sure it works but I just can't get it to work. What am I doing wrong? This is about to drive me nuts!!

uvquickshade creates a mantra material. I imagine you'll have to recreate the material using arnold shaders.

But, before doing renders, I was just trying to see it on a uvquickshade sop to make sure it works in viewport before rendering.

In the end, I simply decided I'll just make a huge grid far in the background and apply a pre-saved .exr texture to it. oh well...

UV Quickshade usually works with op: referenced COPs like in your screenshot
just make sure your grid has uvs, or at least that UV Quickshade has appropriate axis picked up for creating fallback UVs

because based on your Screenshot if your grid is vertical (XY) you will not see much since you don't have uvs and UV Quickshade will project from top so potentially capturing just 1 row from your texture at most

if thats the case, either ensure explicit UVs on your grid (UV Texture) or switch UV Quickshade axis to X or Z axis depending on which way your grid is facing

Oh god!!! I simply did not have any UVs. I feel so stupid.

Thanks for the troubleshooting.
