Before diving into the details of the aforementioned layer types, here are a few tools to help manage the layer stack effectively and efficiently.

Clipping Layers

*Alt + LMB *a layer to make it the child of the parent layer below. In the mixing process, the child and parent layer will be mixed first, before mixing with the rest of the layer stack. A child layer cannot have its own child layer, but a parent layer can have multiple child layers. One behaviour that is worth keeping in mind when clipping layers is that matching color to base on a child layer will sample the parent’s reflectance value instead of the underlying Mix’s average value.

Clipping and unclipping a layer.

In this case, the Noise layer will first mix with the Solid, and then the Liquid layer will mix with the result.
