(Repeating since I erroneously replied to Sebastian only). Thanks. I used osg::Matrixf explicitely, and it doesn't complain anymore. However, I get misplaced shadows now, they're always facing the main camera: http://youtu.be/2pyE1G0752k This is my: 1) 1 pass light camera VS: http://goo.gl/JRRq6Y 2) 1 pass light camera FS: http://goo.gl/fIYeze 3) 2 pass main camera FS: http://goo.gl/nBdWwr
What am I doing wrong? Thanks. 2013/10/11 Sebastian Messerschmidt <[email protected]> > Am 11.10.2013 08:39, schrieb michael kapelko: > > Hi. > Thanks for the info.
