Missing math functions within the material editor

That is actually not the case.

SSAO only applies to the indirect lighting. It happens in many different places in code because there are so many different code paths. Some are in the BasePass some are just in the postprocessing shadows or dynamic skylight shaders. You could easily modify it to apply SSAO in the base pass if you want but it requires a shader code change. But if you really want to, I helped somebody do it a week or so ago just can’t remember off the top of my head where the final place we changed was (and it depends on what lighting setup you use etc).

Thank you, Ryan! It’s more of a general interest, my knowledge of UE4 API is far from handling such cases and I’m knee deep into physics at the moment
