Texture Interpolate
Smoothly and linearly interpolate between two Mutable textures according to a parameter mix factor. If more than 2 textures are input, they will be equally spread onto the [0..1] range and only the two consecutive ones closer to the input factor will be interpolated. The Factor input (0.0–1.0) controls the blend: which two consecutive targets are interpolated and in what proportion.
- Num Tagets: Number of textures between which the interpolation takes place.
WARNING: The interpolation is always made between two consecutive texture indexes, so more than two values are only advised if they represent a single progression or effect. For example, wet skin, normal skin and scaly skin would be a proper use of a texture interpolation node with three inputs. Independent values that can be mixed at the same time with the base texture are better implemented as consecutive texture interpolation nodes. For example, plain skin, wrinkled skin, freckled skin, scarred skin and sunburnt skin are independent, and all five should be able to influence the result to some degree at the same time. In this case, five consecutive texture interpolates of two inputs each would offer all the degrees of freedom necessary to mix them all at the same time.
