Hi I created a patch that takes a movie - cuts it up using jit.scissors then adds a delay to each slice using VZ.delayer and then puts the whole thing back together again using jit.glue. Simple enough and works fine up to and including Max 7 but in Max 8 it doesn't work and you get endless

jit.glue: doesn't understand "jit_gl_texture"

Any thoughts? I tried stripping everything back and the problem seems to be some incompatibility between VZ.delayer (or what's inside it) and jit.glue.

[jit.glue] operates on matrices, all [jit.gl.xxxxx] objects operates on textures.

Simplest solution for this particular situation is to insert [jit.matrix] object between [VZ.delayer] and [jit.glue]. Instead of [jit.matrix] you may consider a mechanism based on [jit.gl.asyncread].

More robust solution is to abandon [jit.glue] and stay on GPU, for example with custom [jit.gl.pix]-based patch instead of [jit.glue].

Many thanks - simply inserting jit.matrix does indeed do the trick and the patch works again. Still not 100% clear why it works without this in Max 7 - guessing it is something to do with the GL? Will investigate jit.gl.pix. Thanks again

Yes in the Max 8 update, vizzie was updated to process using opengl textures rather than jitter matrices. While this update created huge performance gains, there is some unfortunate breakage with patches, such as the situation you describe.
