Houdini turns almost every operation into a reusable node. VEX can chew through millions of points, Python can wire up the bigger jobs, and the whole thing stays editable instead of baked into a corner.
VEX from zero: data types, attributes, common functions, scattering, procedural UVs, and the bits you use every day.
read ->02Procedural thinking: for-each loops, feedback loops, HDAs, TOPs/PDG batch work, and the habits that keep Houdini setups shippable.
read ->03The whole HDA loop: build it, expose the right controls, edit safely, version it, and ship it to your team.
read ->04The hou module: walk node graphs, read and write parameters, generate geometry, build shelf tools, and automate scene setup.
read ->05A searchable library of 950 production VEX snippets, filterable by category, wrangle type, and tags.
read ->Every operation lives in a node graph. Change something upstream and the rest of the setup can update with it.
Multi-threaded and JIT-compiled. Great when Python would take a long walk around the building.
HDAs turn node graphs into tools artists can reuse; TOPs/PDG handles the batch jobs when the asset count gets serious.
The hou module lets Python reach almost every node, parameter, and attribute in the scene.
