Hello, I'm using Houdini on steam.
As the title says, I can't find this recipe.
It works in the FX I use for work.
Is it not included in the Steam version, or do I need to install the recipe

Hi, please contact support about this, the only version where the Otis Muscle Recipes aren't made available is Houdini Core.

I'm assuming that you're trying to load it at the Geometry level and not at the Object level, right?

Does the Otto SOP load correctly? If it doesn't then the problem is probably with your SHFS folder. Support will be able to help you with this.
