How to Use Weight Painting as Masking for Multiple Houdini Inputs

Pedro Alpiarça Shows How You Can Use Normalized Bone Weight Painting as Masks for Multiple Inputs in Houdini

Typically painting masks for multiple inputs in Houdini gives you a stack of layers. This isn’t a problem other than layers have a fixed priority order. Simply put, layer 1 is always under layer 2, and so on. This is easy to fix when you have a few inputs, but when you have dozens of inputs, it becomes quite cumbersome to manage. Weight Painting could be a solution.

Bone Weight Painting in Side FX Houdini works more along the same ways that channels do. This means that priorities are assigned as you paint, not in a fixed stack. This makes it useful for painting masks easily for many inputs. Pedro Alpiarça walks through the process in Houdini,  and discusses its use with a practical example.
