jit.gl.pix input limit

Hi folks,
wondering if jit.gl.pix is limited to only 8 inputs?

I’m building a tiling device that takes 9 inputs. It works fine with jit.pix but in jit.gl.pix simply connecting the 9th input breaks the whole patch.

Test patched attached.
Is this a bug or perhaps a hardware limitation?

Thanks,
Bob.

Same here : the lower right tile stays black on the jit.gl.pix version. Words from C74 guys ?

the lower right tile is blank because it’s disconnected. if i go into the jit.gl.pix gen patch and connect it, the entire texture goes dark. No such problem with jit.pix. I can think of some ways to work around it, just thought i should flag the problem incase it was a bug.

you are limited by the maximum number of texture units your graphics card supports.
this information is found in the OpenGL Status window, found in the Options menu.

Thanks – that’s useful information. Might mean that for compatibility I’ll try to limit inputs to 4 in anything I intend to distribute.

Exit 9tilr with different textures, unless we pack 9 movies into 1 texture…
