Hi everyone,
This is a new Houdini Digital Asset that I've been working on to produce some realistic trees as game-ready props.
The goal was also to test it with PCG to combine the best of Houdini and Unreal!
I'm always looking to make my tools the most art-directable and performant; for this one the biggest challenge was to find the best algorithm in Houdini to make some natural curve paths without losing the optimization phase! Also, still having some useful data information like the vertex color based on the curvature, ambient occlusion, and the gradient of the mesh, plus having some polycount & UV adjustments.
I hope you like it!
