As indicated in the help for shaders

https://lensstudio.snapchat.com/guides/material-editor/introduction-and-concepts/

an 'interpolated' surface position connected to the pixel shader looks like this:

When I try to recreate the example, however, I don't get any color gradient.

How do I get the soft gradients out, did I do something wrong in the material editor?

Hey Franziska Schneider,

The object space positions of the quad corners are larger than 0 to 1. They're -10 to 10 or something like that. So the gradient only appears near the origin. Either the source mesh needs to be scaled and offset to lie between 0-1, or a remap node used to remap the actual range to 0-1.

But the easiest way to solve that is to use UVs instead of positions.

Cheers,
Vincent

Thanks for the helpful answer, the attached shader (with a 1x1 plane) solves my problem.

Cheers,
