I’ve installed the new public downloaded beta provided and installed it.

I no longer get hard crashes on exit of 3rd party program. But I do get the following:

> Some scene cameras still wont show on some clients.

[AIResearcher]

We tried a fix where I initialized the three mono strings to nil and then only initialized them when the string was not nil. It fixed one of the vj tools but not the other.

I will try to work on this some more later, but for now, I just ripped out some of the client functionality as we are really only serving from our application and not listening / watching anything else.

[AIResearcher]

Saw your comment, added checks to parameters and will be trying it shortly. Thanks for the quick reply!

[AIResearcher]

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.

[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.

[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.

[AIResearcher]

There is no hook for OnGUI that will give anything like a TextureID. It may be possible to use something to grab it out of the FBO… However!

The next release of Unity (3.4) should include the ability to prioritize scripts. So that if we have one script with a OnImageRender( ) that we want to capture the results from, we can now make sure that it is called before the second script, (The syphon script that includes it’s OnImageRender( )).

I don’t have access to the beta so I haven’t confirmed this, but am eagerly anticipating it’s release to verify that if our Syphon script calls the very last OnImageRender, that we should be able to include everything except for OnGUI stuff. (OnPostRender) doesn’t provide a TextureID and I’m not sure what is traditional done in this function, but I’m hoping it’s just script updating stuff like positions and AI, and not rendering.

[AIResearcher]

Wow, thanks for all the help!

It would be great to have the texture grab in the OnGUI function, just grab everything before and/or after the GUI (depending on the need). Unfortunately, the only thing I am missing is what is in the “blah” statement or “unity screen texture”.

I’m not sure if you guys know what it is, but I’ll be investigating how to get the right NativeTextureID to Syphon and post back here if/when I figure it out.

[AIResearcher]

Well, it works well, grabs after OnPostRender and OnGUI, etc… but unfortunately (as was expected) ReadPixels is wicked slow.

Now just have to figure out how to grab a NativeTextureID somewhere further down the pipeline or figure out how to do second rendering (maybe a Composting Camera…) I’ll post back with further investigations.

[AIResearcher]

Thanks for the insights. I have been using the SVN version and yes it is much much better.

I’m going to try to insert a yield WaitForEndOfFrame() and then create a new Texture2D with Screen.Width and Height, ReadPixels from the screen into the texture, then provide the native texture id to syphonServerPublishTexture.

I’ll let you know how it goes. I’m not sure how long ReadPixels will take, but it looks like it should work.
