Syphon and Spout for GL3

I can confirm that Syphon works flawlessly with GL3.

I tested recently relatively complicated setups with many servers and clients working simultaneously, transparency support (which was often a problem), transmission between Jitter and other environments (e.g. Processing), etc. I haven't experienced any problems.

Hi,

yes Syphon works, however this message appears in the Max console when I use jit.gl.syphonserver :
'jit_gl_texture: mode is obsolete when using the gl3 engine'

thanks, i've seen those too. you can ignore for now but I'll get them removed for the next update.

Question for Rob:

I added GL3 to my 8.1 version, changed prefs and it runs fine.
Now 8.05 (which opens automatically with the same prefs as 8.1) crashes immediately - because it can't run GL3 - and won't let me revert to GL2.

I want to run some patches with GL2 and some with GL3 while I learn it.

So can I just reinstall 8.05 and not add the GL3 package and will the 2 versions then keep their own prefs and packages and work independently?

Thanks,

Hi Bob.

This crashing on 8.0.5 is an unfortunate oversight we missed when developing the render engine backend for Max 8. You can either modify the max 8 preference file in a text editor to change gl3 to gl2, or you can open Max 8.0.8+ and change the preference there, and then open max 8.0.5.

There is currently no mechanism to manage multiple preference files for different versions of Max 8. The solution I use for this is a script to launch max. 1 for gl2 and 1 for gl3. The script uses this json editor tool called jq to edit the max-preferences file, and then launches max via the arch command:

gl2 script below. change gl2 to gl3 for the gl3 script.

#!/bin/bash
cd "/Users/yourusername/Library/Application Support/Cycling '74/Max 8/Settings"
mv maxpreferences.maxpref temp.maxpref
jq '.preferences.glengine |= "gl2"' temp.maxpref > maxpreferences.maxpref
rm temp.maxpref
arch -x86_64 /Applications/Max.app/Contents/MacOS/Max

Thanks a lot for this Rob. Much appreciated!

it is not working on my machine: i am running the latest max version on mojave 10.14.6 on a macbook pro 2017 with a Radeon Pro 560 4 GB graphic card.
even the simple syphon server help patch doesnt work as intended. what am i doing wrong?

Hi again, Linden. In the help file example above, does putting a jit.gl.slab or jit.gl.texture between jit.noise and jit.gl.syphonserver make any difference? Also, have you tried receiving the Syphon texture with any other clients besides "Simple Client"?

what's printed in the Max console? (restart Max and open this patch to get the full console output)

does the following simple patch work any better?
