From 20836c81851e0df29a8ee9c86e5e5388738c840b Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Tue, 20 Mar 2012 17:43:52 -0600 Subject: [PATCH] st/mesa: set MaxUnrollIterations = 255 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The default was 32 for the EmitNoLoops=0 case. This allows the oZone3D soft shadows test to work properly with the vmware driver. Jose reported that SM3 supports up to 255 loop iterations. NOTE: This is a candidate for the 8.0 branch.
