Houdini Droplet Tool
WARNING: I have received feedback that this tool is not fully compatible with Houdini 19.5+. I will update when possible but for now it may be best to avoid using this tool with anything past 18.5.
Open HDA (Limited Commercial) SOP-based (no fluid sim) tool for Houdini that dynamically creates droplet geometry and wetmap textures. Tons of control over drop shape, behavior, sourcing, and wetmap.

Disclaimer: because this tool doesn’t truly simulate anything, droplet behavior won’t always be believable or look nice. This is especially true when you might expect a droplet to fall off of something – there are a couple stop parameters in this tool, but a fluid sim would work better for drops that roll down a surface and slide off into space.
Open HDA (Limited Commercial) ready for use & modification in Houdini
