texture2DLod undefined in fragment shader for Lighting + Steep Parallax #473

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Execute the parallax test on a baseline OpenGL2 platform

What is the expected output? What do you see instead?
You will receive an error like this:
"no matching function for call to 'texture2DLod(sampler2D, vec2, float)'"
Unfortunately, the baseline GLSL 1.0 - 1.1 specification prohibits the use of 
the sampler2DLod function in the fragment shader. The Lighting.frag shader 
should check the GLSL version and fallback to regular parallax on those 
platforms.
