I'm transfer to transfer a length attribute to fur guides in Houdini 16.

My setup seems quite basic, but I'm probably missing something fundamental on how this is done.

I have created a grid, and added fur to it. Then I've added a Set Length guide process and set the length to be driven by a Guide Attribute.

My thought was to then:
1. Put a sphere inside of the Guide Groom Node
2. Add a length attribute to the sphere
3. Animate the sphere moving across the grid
4. Attribute transfer the sphere's length attribute onto the guides

However when doing this nothing seems to work. Houdini crashes whenever I try to display the sphere. I've also tried with a box instead of a sphere, and the box will display but automatically be smoothed which makes me think something more complex is happening in the groom node and it's interfering with this technique.

Does anyone know how to transfer attributes to the fur system in Houdini 16?

Thanks

Here is one way to do it…not sure if it is the best way or not

Ok, thanks. I'll dig into that and see what I can do
