Yes. Each SOP may have it's own group type requirement: points, primitives, edges…

See the example file for a couple different ways.

Uses a single painted point attribute of your choosing. Most refinement type SOPs take primitive groups so you need to promote the point attribute to primitive attribute either for direct use in group fields or in a Group Expression SOP.

Thanks a lot, i came to much less efficient variant, with subdividing geometry first then deleting parts without color attribute and combining results with a lowpoly mesh after that.

For example you have a low poly model. With a paintsop you draw attribute on it. Can you use this attribute to procedurally add polygons/subdivide/remesh geometry only where you want?

Hi I'm completely new to Houdini. Is this part of Houdini. Is it a plugin, and if so where can I get it? or is the video a tutorial showing procedural plants generation using the normal Houdini tools?

Thanks

There are probably no easy way to do it. This guy just shown his own tool made for his project. i bet it took a big amount of time to implement it all in hdk.

If you still want easy way, you could look at speedtree plugin. It has houdini connection. But i don't see a real reason for this variant, why you need houdini at all then? The strength of houdini is ability to create such tools by yourself without plugins.

If you want to learn you have to look at lsystems tutorials. https://vimeo.com/51771303 [vimeo.com]
