Hi guys, I've run into a phenomenon in houdini which I don't know whether to be concerned about, or glad because it makes things more homogeneous. Basically I've been testing light attenuation in mantra as well as sss settings to determine whether they change based on the global scale of the scene. I would have expected that if I scale my scene up by 10, my area light attenuation would fall off a lot quicker, based on quadratic falloff laws. I expected to see some difference in the appearance of sss as well. Strangely though, adjusting scene scale has no effect on either of these things. I've attached 2 images. one is the scene with a scale of 1, and in the other, everything is scaled up to 10. There is zero visual difference in the two images. Am I right in thinking this is physically implausible?
