Snow mesh generation tool (Houdini) (Early 2021)
Houdini tool that generates a procedural snow mesh on top of an input 3d model. It is capable of adjusting the amount, density, and size of the snow elements that conform the coat. Also, there are specific optimization-oriented parameters that reduce the poly count of the mesh with minor lost of the main shape of the coat.
The tool’s parameters can be adjusted to work with different scale 3d models:
The tool has been exported as an HDA, and it can be used inside Unreal Engine 4:
The tool consists in 2 main process: Raycasting snow elements over the model and converting them into a mesh, and optimizing that mesh with Uniform and Adaptive remeshing nodes.
