Hi,

That's make more sense to me. Thank you so much. I finally made my movies show in the window but I couldn't make the jit.gl.slab work (jit.gl.slab seems can not blend anything after jit.gl.videoplane). Now I am going to send those videoplanes to jit.gl.texture first before jit.gl.slab. 

My question is according to what you said, after I compose my video in the slab, I send to jit.gl.videoplane again and use[jit.gl.videoplane @transform_reset 2], should I put a new window name on it? I mean, like jit.gl.videoplane foo @transform_reset 2] )??

thanks again
