Blending and Mixing Normal Images

There are two different ways to blend normal maps: Alpha and opacity, and normal perturbation.

Blending with Alpha

When blending with alpha and opacity, the foreground normal image is composed over the background image using the alpha channel and the opacity value. The final result is normalized.

Compose Normal Alpha

To Blend with alpha and opacity you use the Blend and Mix nodes in the Compose nodes toolbar sub menu.

When blending with normal perturbation, the normals of the foreground image perturb the normals of the background image.
