Change between textures gradually, allowing to fully apply one texture, the next one, or any proportion between them.
Factor: Number between 0.0 and 1.0 that determines to what degree are two consecutive textures interpolated. 0.0 will fully apply the texture at target 0, 1.0 will fully apply the highest index target texture. Intermediate values will progressively interpolate between them. For example, if there are four inputs, a factor of 0.6666 will mostly represent the texture given to the Target 2, and a factor of 0.5 will be an interpolation between the textures at Target 1 and 2 applying them both in equal proportion.
Target (index): Texture input for this index.
Texture: Final texture. It is either a single texture from the input or the interpolation between any of two consecutive target indexes, depending on the chosen factor.
