i hope scons remains until we can build mingw with cmake successfully because the render speed differs greatly between vc12 and mingw: BMW1M-MikePan scene with nvidia geforce 660 scons+mingw => 01:08 cmake+vc12 => 01:48 40 second spent on bvh! in vc12, which would make kill animation rendering times Regards Yousef Harfoush bat3a at msn.com
