Learn about stacking shaders in layers.
- [Instructor] Now that the Bifrost channel data…has been combined, we're ready to use it as a mask…between two Arnold materials.…I'll open up the Hypershade,…and I'm looking at the graph for the mask.…I want to load in a couple of materials…that I've prepared, and those are in the browser window.…I've got that hidden temporarily, so bring that back.…And let's middle-mouse click and drag…the water_clear over into the graph.…And also middle-mouse click and drag…water_white over into the the graph.…
I don't need the browser anymore, so I can close that.…And now I need a layered shader…to combine these two materials.…Click in the graph to get a focus,…and then press the Tab key and type in L-A-Y…and choose layeredShader.…I'll select it and its shading group…and just get this staged up a bit.…Select the layeredShader node and let's rename it…water_layeredShader.…We should also rename the shading group over here,…again call it water_layeredShader SG.…
With the layered shader selected, go to its attributes…and we want the compositing flag to be set to Layer Texture.…
