Free Houdini Tutorial: Volume Style Transfer With ONNX

Support us on 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!
