troubles on unity 5.3 (OSX)

[MartinHN]

Hi,
I can't make work syphon on unity 5.3
its due either to the 5.3 updates on OpenGL 4.x core,
or my macbookpro with the good old intelHD3000 and apple's poor GL support.(unity runs with openGL3.3 and I'm not sure to support it fully)

in case somebody else have this : the only workaround for now is to run unity with -force-opengl

[Edit] :
my bad it comes from syphon framework ,
this fork claim to fix that : https://github.com/eromanc/Syphon-Framework

The problem lies in the new OpenGL4.1 that Unity 5.3 comes with. You can revert to an older OpenGL version in Unity 5.3 by going to

Edit > Project Settings > Player > Other Settings

There you will see the 'Graphics APIs for < your platform here >'. If you deselect the checkbox you can reorder the graphics options. What helped me was to drag OpenGL2 to the top. After that the Syphon package (version a17) worked again.

Hope this helps.

Hi,
Using the legacy OpenGL does fix Syphon but creates other bugs, in my case the standalone player crashes when I have multple displays (which is needed for my videomapping installations).
It would be great to update the lib for OpenGL 4.1 soon...or is it related to the Syphon framework itself ?
Thanks !

The Syphon framework requires updates for 4.1 GL. They are planned, hopefully soon.

[leolodreamland]

hopefully soon, please?

@MatteoFantasy did you try exporting as 32-bit (x86)? This prevented a multi-monitor crash on my end (OSX 10.10)

[MatteoFantasy]

@bombarie Building in 32 bits indeed prevents the mulit-monitor crash but the Syphon plugin doesn't work (no syphon server created). If I remember correctly Syphon is 64 bits only, and the logs seem to confirm this :

Couldn't open /(...)/Plugins/SyphonUnityPlugin.bundle/Contents/MacOS/SyphonUnityPlugin,
error: dlopen(/(...)/Plugins/SyphonUnityPlugin.bundle/Contents/MacOS/SyphonUnityPlugin, 2):
no suitable image found.  Did find:
/(...)/Plugins/SyphonUnityPlugin.bundle/Contents/MacOS/SyphonUnityPlugin:
mach-o, but wrong architecture

[bombarie]

@MatteoFantasy That's strange because making a 32-bit build actually worked for me. To be clear: either the SyphonServerTexture script or custom resolution script worked for me, I made the player use OpenGL2.1 (Project Settings > Other Settings > Graphics API for Mac > OpenGL2) and then exported as 32-bit application. Syphon was outputting images just fine.
I just re-tested this succesfully but I don't have a multi-monitor setup with me right now, and my current system is OSX 10.9.5, not the OSX 10.10 I mentioned yesterday. I do remember preventing a startup crash along the line by first disconnecting some monitors, starting the app, then reconnecting the
monitors. I forgot which combination of settings I used then, sorry to say, but I hope this helps you in any way.

[leolodreamland]

i don't build, so this isn't an option for me - i am going back to 5.2 for
the time being.

@leolodreamland Oh, I was actually only having problems with the builds, not from within Unity. If you set your Player Settings OpenGL to 'OpenGL2' (OpenGL 2.1) then the Syphon plugin doesn't scramble the output. I had a 3-monitor setup working just fine that way. My setup was 1 monitor being Unity and MadMapper and using two attached video projectors to map the output onto. This was on OSX 10.10.
Have you tried OpenGL2?

[lm-n]

@bombarie thanks for the advice 💃 OpenGL2 is super helpful!

[initi]

Hello,
any update of Syphon for Unity5.3.3 please? Its still crashing in build and switch to OpenGL 2.1 does not have a sense. Thank you in advance!

[vade]

No Update to syphon. You'll know.

[leolodreamland]

i'm happy with 5.2 for now. i haven't seen a killer use for the new stuff. yet. btw isn't 5.4 out soon?

[Harvey3141]

If you really need Syphon in 5.3, you could try this

https://github.com/keijiro/Funnel

[benkuper]

As a workaround, and until syphon is updated or funnel implement client support,
i managed to get Syphon work in Unity 5.3 by launching it with -force-opengl from the terminal. It forces the use of GL 2.1 (and disables some of the new features inevitably).

UPDATE : the -force-opengl argument only works in editor, not in standalone mode.
you can actually choose to not use GLCore or Metal in the player settings ("mac auto settings")
The editor will also force itself to use GL2.
For me, this works well in editor, but in standalone i had to export from Pro version and disable the unity splash screen.

[leolodreamland]

Why use 5.3 then? 5.2 is fine for me for now...

You can select which version of OpenGL the app will support on the Player Settings.

[leolodreamland]

ok, so 5.5 removed legacy opengl support. no update nearly 18 months later?

You can get your money back with proof of purchase. ;)

do i still get my free inflatable horse?
