Broken: (example: 2.70 19e627c
Worked: (optional)
**Short description of error**
When using a stack of textures with painted masks (stencils), normal maps are unaffected so both are fully visible.
Example, in the attached blend, the brick pattern is visible via the interaction of specular highlights with its normal map, even in areas that should only show moss. The other maps - diffuse, spec and gloss, appear to work correctly.
The bug presents in the viewport (GLSL), game engine and blender internal renderer.
