From d75b34394b5c53b0a5e8144dd28f956fbc8b90b2 Mon Sep 17 00:00:00 2001 From: Jim Van Verth Date: Thu, 19 Apr 2018 14:47:53 -0400 Subject: Remove ambient clamp hack for analytic shadows. The hack was added to make analytic ambient shadows match the geometric ones exactly. Removing it does produce a slight difference, but it's only visible at full black values (and then, only slightly) and this makes room to pass a blend parameter for falloff. Also fixes an issue with filling out arcs in the shadow tesselator.
