In my efforts to make the shadows soft, based on the formulas for penumbras, I finally realized that my method does not support physically correct penumbra softness, but I will explain the reason for this when I do the tutorial.
Until then, here’s what I came up with, after applying some Gaussian blur to the final shadow image. (variable degree of softness)
Even if it’s not physically correct, I still think the softness looks good enough.
There’s also an interesting looking result when the radius of the Gaussian Blur depends on the distance from the light…

That is pretty cool, the radius trick makes the light diffuse, witch is physically correct.
