Unity3d 3.5 Breaks Syphon Implementation

[AIResearcher]

The latest build of Unity3d (3.5) crashes the Syphon Server Plugin Implementation.
I have verified this on the latest version of the plugin demo.

I am not sure how to go about fixing it, other than starting to comment out calls to see what doesn’t. I have attached a stack on the main thread (dispatch queue) to try to help.

I’m not sure how many users you have on Unity3d, but we really love Syphon and use it for core functionality.

Brian Gibson who does most of the Unity work has an update – drop him a line to get hold of it.

We really need to get him to dump that on to SVN. Im doing a job with him, so I’ll bug him about it later today when I see him.

[AIResearcher]

Thanks for the message. I tweeted him. Would love to get a hold of it and help test it out.

I appreciate all of the support Syphon has given us over the past year.

[bangnoise]

We’ve just put a download up. It includes some fixes made today. Let us know how you get on.

http://syphon-implementations.googlecode.com/files/Syphon%20for%20Unity%203.5%20Public%20Beta%202%20a1.zip

The source is now on svn as well.

[Brian Chasalow]

Regarding that last link bangnoise posted: there is a bug in the .bundle file relating to syphon server output from Unity. please use the fixed .bundle available at http://www.chasalow.com/Unity/SyphonUnityPlugin.bundle.zip , (just replace the .bundle with this fixed one)
this should get updated on the SVN tomorrow.

sorry about that

[AIResearcher]

Thanks for the update. I’ve been playing around with it.

Unfortunately, although it runs fine with the example project, it seems to crash on

GL.IssuePluginEvent((int)syphonServerTextureInstance);

in OnRenderImage( )

What I did was I took our project and removed all old syphon components. Then placed the scripts and newly created bundle in the plugins folder. I added the Syphon script to the root game object and a SyphonServerTexture to our camera.

I’ve been trying to narrow down the issue. I got to the point where I ripped out all the original game objects and have just two, a Syphon script and a default camera. I’ve also been looking through all the various settings (default resolution, quality settings, render path (forward / deferred lighting / etc…) to try to see what about my project is the problem. I will continue to debug as much as I am able, I just wanted to let you know what I was doing in case I didn’t set it up properly and let you know that I am excited to have an update to help debug.

I seemed to have fixed the problem!

I accidentally did not keep the directory structure for the .cs files inside the plugins directory. Restoring them to the proper places inside the plugins/ folder seems to have fixed the problems.

I will continue testing and let you know what I find on the google code SVN.

I try to reveice Arena’s video into unity35 but it dont successul, unity can’t find the server by arena~~ the 34 version at least can find the first server

[Brian Chasalow]

read the readme.txt: While the game is stopped, click the server name on the Syphon script, and click ‘add’. look at your SyphonClientTexture script you wish to receive video on, and change the appName / name to match.

Expect future updates to take care of some of these details for you, but for now, i’m curious: what part of the instructions are confusing? thanks.
Brian

[Brian Chasalow]

on SyphonClientTexture, client app name should be “Quartz Composer” (no quotes) and client name should be “Untitled”

Getting an error on sample launch.
seems to be with line 513: GL.IssuePluginEvent(updateContext);

[bangnoise]

nodfnord – Unity version, plugin version, what is the error message, log, etc. etc. etc.

[nodfnord]
