For some reason, the softening size is minimum in my documents of 0.01. I’m not sure this makes sense. I think this parameter should be limited to at least the document precision. I have a document that has 0.001 precision, yet I am constrained to an order of magnitude more for edge softening?
I got used to some how materials work in Cycles. I think some of them have minimum values I think should be more finely tuned for non-linear response; and thought the softening was annoyingly the same.
