PBR Incorrect mul

I found this fragment by analyzing your and unity 5 shaders, after implementation in my engine:

Dot clamping ndotl and ndoth is incorrect, correct just dot.
See:
float ndotl = dot(n, l);
float ndoth = dot(n, h);

Is needly check brdf.dds

Please, check this file. It corrupted(i can see this using any program. For example another brdf.dds files is fine(derkreature/IBLBaker for example))

"Ocean" error

Problems with quad(Forward+ Sample)

Hi

I think,what you forgot make:

                glActiveTexture(GL_TEXTURE0 + tex_unit);
before
                glBindTexture(GL_TEXTURE_2D, framebuffer->GetColorAttachment(tex_unit));
and
                glBindTexture(GL_TEXTURE_2D, 0);

because we can get black screen

Correct version for me(this fragment is correct for OGL4(http://docs.gl/gl4/glActiveTexture))

        void GLFBO::BindColorTexture(size_t tex_unit)
        {
                glActiveTexture(GL_TEXTURE0 + tex_unit);
                glBindTexture(GL_TEXTURE_2D, this->GetColorAttachment(tex_unit));
        }

        void GLFBO::UnBindActiveTexture(size_t tex_unit)
        {
                glActiveTexture(GL_TEXTURE0 + tex_unit);
                glBindTexture(GL_TEXTURE_2D, 0);
        }

OpenGL version

Could i run this project on opengl version #330?

Forward+ EarlyZ

Hi, it's again i'm :)

I not seen EarlyZ - Where it? - Forward+ must be with EarlyZ

PBR Directional Light

How implement this in PBR context?
Or use similiar as in simple lighting?
