Finnaly the depth buffer is working with mass effect 3. I also used SSR and MXAO shaders from Quint shader set.
I didn't rewrite the shader, just found it on this forum and tweaked it to work with ME3, As soon as I find the thread I will credit the the creator.
In the video and some screenshots you can see SSR (screen space reflections), it isn't perfect, but it adds some nice reflections in in some angles. The downside is that it adds reflections on all surfaces. But the depth buffer works flawlessly. Also works with ME2.
How did you get depth of field to work with ME2 and 3? I have the latest version of Reshade (4.1.1 but also tried with 4.0.2) and the latest Quint download. I keep getting an error with quint_dof not compiling. Other shader effects like quint_bloom and quint_Lightroom work fine, but MXAO and SSR don't appear to have any effect at all, but have no errors.
