Im unsure how to create low level fog in unity, are there any tuts or links that would help me create a low level fog in a tomb, any help would be great

You could look for papers on atmospheric rendering, there you should find the math about how to do it. (I guess it’s a line integral over the height-dependent light attenuation. With a suitable dependency on height, the integral should be analytically solvable and then it can “easily” be implemented in a fragment shader.)
