Summary0003910: Attempting to use Parallax mapping causes Fragment shader failure
DescriptionUsage of a neutral parallax map as described by Kloot in this thread (http://springrts.com/phpbb/viewtopic.php?f=13&t=29108) results in a totally white map and shader errors.

The same map works when loaded in 94.1 but fails in latest dev builds.

Local testing reveals parallax mapping was broken somewhere between 94.1.1-423-g2a89870 and 94.1.1-594-g8f53c96

In latest dev builds this is the result: http://i.imgur.com/d3TYZ1P.png

Error in question:

[Shader] Warning: [Compile]
shader-object name: GLSL/SMFFragProg.glsl, compile-log:
Fragment shader failed to compile with the following errors:
ERROR: 6:209: error(0000143) Undeclared identifier specularTexCoords
ERROR: 6:209: error(0000202) No matching overloaded function found GetParallaxUVOffset
WARNING: 6:209: warning(0000402) Implicit truncation of vector from size 1 to size 2.
ERROR: error(0000273) 2 compilation errors. No code generated
Steps To ReproduceSet parallaxHeightTex=parallaxmapname.png; in mapconfig and load map
