Keep up to date with Natsura

Natsura is a Houdini-native foliage toolkit built on a growth graph engine. SpeedTree is a proven standalone tree modeler. If you’re choosing a vegetation foundation for the next decade, this page explains the difference.

You can build foliage tools in Houdini. We did — three times. This page explains why, for almost every commercial team, it makes more sense to build on Natsura than to own a vegetation engine yourself.

Natsura is a fast, flexible foliage engine inside Houdini, with artist-facing tools on top. It plays well with the Houdini graphs, HDAs and foliage workflows you already have, and outputs clean, rigged assets for modern game and film pipelines.

Unreal Engine 5.7 brings PCG, the Procedural Vegetation Editor, and Nanite Foliage. Natsura sits upstream as a Houdini-based growth engine that feeds those systems with structured, Nanite-ready trees and ecosystems.
