Commercial Use

Natsura is a plugin for SideFX Houdini. It does not include Houdini, so you need a separate Houdini licence from SideFX. Two licences always apply at once, and you must stay within both: the Natsura EULA and the SideFX Houdini EULA.

The simplest way to think about it: Houdini decides whether your work can be commercial, and Natsura decides which features you get. Where the two ever disagree, the stricter rule wins, and that is almost always Houdini's.

Houdini editions

SideFX sets these, and the full details are on their site. In short:

• Apprentice: free, non-commercial only. Watermarked output, with resolution and export limits.
• Indie: limited commercial, for small studios and individuals under SideFX's revenue and usage caps.
• Commercial (Core / FX): full, unrestricted commercial use.

Natsura editions

This is what each Natsura licence supports on our side. It does not override SideFX's rules.

"Commercial on the Natsura side" means the Natsura licence permits commercial work. It does not mean Houdini does. If your Houdini licence is non-commercial, your work is non-commercial, whatever Natsura tier you hold.

Running a higher Natsura tier on Apprentice

Natsura Indie, Pro, and Studio can technically run while Houdini is in Apprentice mode, but that does not make Apprentice commercial. You still have watermarks, resolution limits, and export restrictions, and putting Apprentice output into a commercial pipeline can break SideFX's EULA. To do paid work, get a commercial Houdini licence (Indie or Commercial).
