Combining Bifrost channel data

- [Instructor] We've extracted and preprocessed…the Bifrost channel data for three different channels.…I've got them rendered in the Arnold RenderView snapshots.…Here's churn, vorticity, and velocity.…Now, we will combine all of these with…a layered texture to form a mask.…I'll go into the Hypershade,…and so I'll have even more room for the graph.…I'm actually going to close the browser window as well.…And here's what we have so far.…We have velocity, vorticity, and churn.…

Let's create a layered texture.…Press the Tab key and type in L-A-Y…and choose layeredTexture.…Rename it, call it water_mask_layered_texture.…With that node selected in its Attributes,…set the Color to a pure white.…Now, we'll take that churn data and use it as a mask.…Open up the input to the water_mask_layered_texture…and in input zero, you'll see the Alpha channel input.…

Connect the churn_aiUserDataFloat out value…directly to the Alpha channel of input zero.…Connect the Out Color of the layered texture…to the Color of the aiUtility node.…
