I’m working on an OB3D external which would require at least 2 matrix inputs.
I’ve managed so far to have one matrix input working (by looking at jit.gl.videoplane), but I have no clue on how to add an additional matrix input.

I read the relevant section in the SDK manual (24.23) but frankly found it quite vague and have no idea how to start implementing it. Could anybody please provide an explanation on how to do that or ideally relevant code excerpts (e.g. from jit.gl.mesh).

I’ve been blocked for several days on this now and have no idea how to move forward…

Thanks a lot!!

basically, in your max wrapper you create the proxies in your new() function with the max_jit_obex_proxy_new() function.

then in your max_jit_gl_*_jit_matrix function, you need to find the input that the matrix is being sent to with the max_jit_obex_inletnumber_get() function, and notify your jitter object of this inlet, by setting an attribute, before calling the jitter objects jit_matrix function.

let me know if you need further clarification.

Thanks Robert!
