Houdini Roots And Veins System HDA

Houdini HDA asset with which you can create stunning custom roots or veins systems on any surface with full control over the settings.

The root system itself is based on a Find Shortest Path SOP, however this tool has a strong procedural VEX-coded implementation and allows you to create stunning systems just in a couple of clicks. The tool includes following:

• Geometry preparations. Because the roots system heavily depend on topology, this tool does all the preparations for you, when needed, just in one click.
• Procedural optimised VEX-coded Start-End scattering system with a lot of controls over the iterations, length, spreading, density etc.
• Built-in cleanup system, that solves a typical problem with a complanar geo after the path construction;
• Post-effects, such as colorising based on a root number, and shifting roots by normals
• all the necessary attributes, such as @curveu and @name for selection.

This tool also includes a HIP-file with an example, how to use this asset in different situations. There is also a suggestion, how to improve the Polywire look after all.

You can also watch my tutorial, where I explain how to create a base of this system: https://youtu.be/xKRnBFYKYn0

UPD: asset and scene were updated to Houdini 19.5 version!

Usage (for beginners):

open the .hip file provided, than install the asset (Assets->Install Asset Library). Go into the "root system" geo and check the different approaches of the tool by changing the number in the Switch SOP.

Thank you!
