Understanding shader graphs in Reality Composer Pro

I am very new to shaders, never used one of the large systems like Unity. However I have started exploring visionOS programming and that led me to create some effects for materials in Reality Composer Pro.

I have been overwhelmed with the possibilities, but also kind of lost. I understand that RCPs shaders are based on MaterialX, so maybe there are tutorials on the web that would cover how to create procedural effects (fire, wind, water, etc)? I’ve stumbled through…but it’s slow going. Are there any good resources that talk about how to use the various nodes to create procedural effects?

For example, it took me a while to figure out that using the “time” node allows me to animate cool color changes, especially when combined with various math and remap nodes.

Just looking for some basic resources I think. Would the shader graph tutorials about Unity, apply to using RCP? Are the node types similar enough?
