Description

After enabling forward shading materials with their decal response set to "normal" have incorrect shading. In the example project there are many pointlights and their specular highlight doesn't display properly.

The licensee explains that the normals passed into the shader are not normalized which is adversely affecting shading.

The decal response "Color Roughness" appears to be working correctly.

Steps to Reproduce
  1. Open attached project
  2. Notice the even specular highlight strength
  3. Enable forward shading and restart

RESULT
The highlights on the material with decal response set to (normal) are significantly dimmer.

EXPECTED
The visual appearance of the specular highlights should be the same after enabling forward shading.
