pbr-shader's Issues

Good change for your shader

Sir, I have applied your shader, it looks fine in code style. Please accept my appreciation firstly. I would like to point out that there's some ' wrong in the code logic in file "src/main/resources/shader/fragment_generated.glsl"
It would be good if replacing "Lo += kD * (albedo / PI) * radiance * NdotL;" to "Lo += (kD * albedo / PI + specular) * radiance * NdotL;".
