Is this truncated sdf?

[Jenix8]

Hi, thank you for your great package. It also works well with complex mesh objects.

Since I had to use the sdf values directly, I took out the values of render texture using the code at HERE.

However, I found that the sdf values are clamped into [0, 1], called truncated sdf (tsdf), that is, the sdf values written in render texture inside the object were not negative but 0, and if the sdf is bigger than 1, the values written in render texture are 1.
(I think there may be a problem with the code in the link above..)

I need the real sdf, so I want to know the parts where to clamp the sdf values and how to modify it.
