| Post subject: | Binding Depth textures |
Pardon me if this is an idiotic question, but I can't seem to find a way to bind the depth component of a render target to a texture unit in the pipeline config. I am working up an example of screen space ambient occlusion, but I need access to the depth buffer in the shader... |

Depth attachments have a special buffer index which is 32. You can find this info in the pipeline documentation 
SSAO is quite cool, I also started a very small demo (3 hours of work in total) some time ago based on this article. It is basically working but still needs a plenty of tweaking. So I'm looking forward to see what you will achieve. |

That is one of the articles I am working from, but you also might want to read his partner's devlog, here |
