Free Houdini Tutorial: Volume Style Transfer With ONNX

Support us on www.patreon.com/entagma
In an earlier episode we took a first look at the new ONNX inference node, a node that allows us to use trained neural nets inside Houdini. And today we want to use this node for something usefull - Volume Style Transfer! We want to apply a pretrained style to voxels instead of pixels and give our simulations a unique look and much more detail. And we're going to do all of this using just a tiny bit of machine learing and a lot of SOPs!

Very cool and unexpected integration. Would love to see more ways like this that these tools can be implemented beyond wholesale image creation/slapping a coat of paint on an image.
