Texturing GL objects with movies/images

Hi guys,

I’ve been refamiliarising myself with Max, after taking a course in it a couple of years ago, and as part of that I wanted to get a sense of Jitter. One resource I’ve found useful, although old, is Paul Schuette’s Demystifying Max/MSP (https://www.paulschuette.com/wp-content/uploads/2013/01/DEMYSTIFYING-MAXMSP.pdf). The only thing I’ve come across that I flat out cannot get to work is on page 44, I’ve copied the paragraph below:

“There is one way, and only one way, in which you can meld the two halves of Jitter. jit.gl.render can create a "texture" on an object out of a still or moving image.”

I’ve tried to build this just as in the patch, didn’t work; I can get a clip to play out of the jit.qt.movie object (also tried a jit.movie object); and troubleshooting via print shows me that the right messages are coming out — but jit.gl.render just isn’t taking the texture and applying it to the shape. I’ve tried YouTube videos, Max’s built-in tutorials, everything I can find, and I don’t doubt the answer is there, I just can’t work it out.

I’ve put panels behind the pieces of code that (as far as I can tell) are the relevant ones.

Any help on this would be much appreciated!

TL;DR — can’t work out how to get a texture onto a rendered object, even though all the right messages seem to be sending (but I'm new to Jitter).
