Ha! Give it time. From what I've seen you do a great job already!

Cutout Opacity and Normals are under the surfaces tab. Cutout opacity allows you to take something like the splats and apply a predefined shape to it. Next time you load a splat, take a look at both of them.

The cutout is a simple black and white image where the white part is visible and the black is hidden.

Normals act as an extra detailed bump map that iray renders as 3D.

It can get complicated and frustrating, but its awesome when you get sorta the hang of it! Been doing it a couple years and I still have way way more to learn!
