i compile the solution under vs2015 with recompiled glew lib, sb7 lib. but the bumpmapping project cannot work, it seems the texture cannot display properly. screenclip

Looks like the problem was in the vertex shader. The wrong light vector symbol was being used in the calculation.

I've attached the fixed shader file. bumpmapping.vs.zip
