The mix_RGBA is used to blend or add two colors or textures. It returns a linear interpolation of input1 and input2 according to the mix_weight attribute. A mix_weight value of 0 outputs input1, a value of 1 outputs input2, and a value of 0.5 mixes evenly between input1 and input2.
Swaps Input 1 with Input 2.
Input for color one.
Input for color two.
Allows you to control the amount of blending between colors. Connect a texture to the mix_weight to control the blending between input1 and input2.
