Sorry about that… got distracted by a vade link that set me right. I had forgotten that jit.gl.hap and jit.gl.pix were in the gl and thus needed drawto as well for the 4 different jit.windows. Here is what I ended with. It works!
It’s 8 poly HAP players with xfades, allowing me to have 4 different windows go to 4 different projectors, plus a 5th for monitoring (hackintosh).
Any optimization ideas, or ways to make this even better, are always welcome :)
