Free Houdini 21 HDA: Neural Terrain Paint and ML Train Terrain with Example Scene (Cody Spahr)
Original title: Neural Terrain Paint
Overview
Cody Spahr shares this project on the SideFX Content Library to show machine learning workflows for heightfields in Houdini 21. It contains two HDAs: Neural Terrain Paint, which sculpts heightfields with a paint brush while pre-trained ML models deform the terrain through the ONNX Inference SOP, and ML Train Terrain, which trains custom models from heightfield edits and comes with a pre-built erosion network.
The download also holds an example scene (NeuralTerrainPaint.hip) and a trained model file (model_Arid.onnx), and the page notes that three example ONNX files are fetched from the HDA's parameter interface. NeuralTerrainPaint.zip (about 193 MB) is a free direct download under the SideFX Standard License.
What You Can Learn
- Paint heightfields with a brush while pre-trained ML models deform the terrain via the ONNX Inference SOP
- Train custom terrain ML models from heightfield edits with the ML Train Terrain HDA
- Open the example scene to see how both HDAs fit into a heightfield terrain setup
