i'm layer alpha channeled video through jit.videoplane and rendering it out with the jit.gl.render

it all works fine to jit.window but i need to keep the combined image in the patch for further processing

i've spent the best part of a day messing around with loads of configurations but can't make what i thought would be a simple function work

By doing the alpha channel compositing the way you're doing (combining several jit.gl.videoplanes with transparency), you need to render the end-result to a texture to continue processing it. Check here in the forums for "render to texture" or see the help file of jit.gl.node (with the capture attribute).

Alternatively, you could do the alpha channel compositing of the 2 videos within a chroma key shader that instead of simply making a video transparent, combines them internally (i.e, load the co.chromakey.jxs inside a jit.gl.slab).
