Blender 3.1.0 and later

• RBF Nodes is a node-based RBF solver for Blender. It allows to drive multiple properties with multiple driver values.  RBF stands for Radial Basis Function and is used to approximate or interpolate a given set of values at any defined sample point. RBFs have a wide range of applications and can be very helpful when regular ways of driving values fail in 3D animation. It basically allows the user to interpolate multiple values based on a set of sample values, or poses which are defined by the artist in advance. For standard drivers, such multi-value interpolation is not easily, or even impossible to achieve. Like, a driver in Blender can have multiple input values but only one output target. RBFs can solve multiple output values based on multiple input values.
