Texture Interpolate - anticto/Mutable-Documentation GitHub Wiki
Linearly interpolates between two or more Textures according to the mix factor. If more than 2 Textures are input, they are equally spread onto the 0 to 1 range and only the two consecutive closer ones to the Factor are interpolated.
[!NOTE] It is only advised to use more than two Targets if they represent a single progression or effect.
