- The first thing we'll do is change the Blending value to "1"(one). The result is that the Blender node displays as Blue instead of purple or red. You'll notice that "1"(one) favors the Blue "Input_2" now.

• Next change the value Blending value to "0"(zero). You'll notice that 0(zero) favors the Red "Input_1" now.

Take a step back. Let's keep the Blender value at "0"(zero). Remember that - in a mask - anything white becomes visible and anything black becomes invisible. So, what does that mean when working with a Blender node? Let's see.

First thing, make a black and white checkered surface. To do this,

• New Node>2D Textures>tile
• Change the color of Tile_1 to Black
• Change the color of Tile_1 to White
• Plug Tile node into the Blending input of the Blending node. Remember that the Blending value should still be set to "0"(zero).

Notice there, at this point, no changes occuring in your Blender node. This is good, as there is "0"(zero) influence from the black and white mask on the Blender node. Next, let's maximize the influence of the Tile mask on the Blender node. To do this,

• Change the Blender value to "1"(one)

Notice that anything white in the Tile mask causes the Blender node to use the Input_1 color(Red). Anything in black from the Tile mask causes the Blender node to use the Input_2 color(Blue). Cool!
