I've decided to assign colors to different shadowTexCoord.z values. That's my final pass fragment shader now: http://goo.gl/n6FrVB Turns out shadowTexCoord.z is in the range (-51.85;-50.80) for the scene for some reason. And, as you see from this video: http://youtu.be/_NQLCXYveHYshadowTexCoord.z values change when I move main camera. I don't know how to interpret this. Any idea? Thanks.
