It would be great if anyone can help me out with this issue.

I am working with 3D models in .DAE format. The patcher below works fine on a MacBookPro, renders appear just fine after processing them with jit.matrix. I am able to manipulate the images using other jitter effects.

But on Windows, the Max console alerts "jit.gl: invalid extension called". The rendered model apperas for a second o or two, and then it dissapears. Max has crashed a few times already, particularly when trying to load new models, or when clicking on the message "drawto". I am assuming that there is something missing on my PC, may be some plug-ins, or something else I ignore regarding Max GL module. Can anyone HELP me, please!

I am working with PC with Windows 8.1, 32 GB RAM, Intel Core i7 4Ghz, Nvidia GeForce GTX 760 4GB.

Please, follow the link to download and use a couple of the .DAE models I am using.

it's possible you are running out of memory, or it's possible the windows software GL renderer is not able to render the gl.model. you will have much better luck using hardware rendering.

to achieve your desired effect, you simply capture the gl.model to a texture with jit.gl.node, and perform the chromakey blending using a jit.gl.slab. i've taken the initial steps to convert your patch.

search the Max Reference Browser for "Video and Graphics tutorials" for updated jitter tutorials.

Thank you so much Rob for your fast response and advice! Your patcher worked just fine!

Although, I believe the original issue has to do with the Windows' software GL rendering config. I don't think it has to do memory, my Mac laptop (OSX10.10.5) has only 8Gb of RAM, and the PC has 32Gb... Also, my laptop's video card (Intel HD Graphics 4000 1024 MB) and processor ( 2.9 GHz Intel Core i7) are less powerfulI than my PC (Windows 8.1, Intel Core i7 4Ghz, Nvidia GeForce GTX 760 4GB).

I'll have to check also if my PC is running with the correct graphic processor. I've found that I could set it to "High performance NVIDIA processor". I'll post what are my results, if that helps someone else.

Anyways, your patcher worked just fine without doing anything with the video card. We were able to send the jit.world signal to a jit.matrix, and then do the video mixing we wanted.

On OSX works fine, but impossible to render 3D Models over a jit.matrix on PC . Why?
