Your hardware is not capable of executing these shaders. The function
OffsetMapping (from data/glsl/default.glsl) has three texture look-ups that
depend on the value of the previous look-up. This function is being called by
two shaders that use its return value in a fourth texture look-up. This
creates four texture indirections, but this hardware only supports three. I
would recommend contacting the developers of this application and ask if they
can come up with an alternate shader.
