Sorry if this is something really obvious, I'm sort of new to geometry nodes. I have a simple geometry nodes setup that distributes picture frames on a mesh. These picture frames also have a procedural slashing effect with different values that control the effect. I can't for the life of me figure out how to control the material with geonodes... For the geonodes setup, I have the modifier applied to a cube. It uses "distribute points on faces," "instance on points," and "rotate instances" to place the portraits. For the shader, there are 5 values I want to be able to control, all floats (unless there's an easier way to randomize the images? My current idea is to input a random float, and then determine the image based on the value).
I've been trying to figure this out for a while with no luck, so any help is appreciated ^^'
