When I have more time, I will dig into it more. Do you have other suggestions in the mean time?<br>

Hi Raymond,<br>
<br>
Unfortunately the output doesn't yet provide anything clearer to what<br>
might be amiss.<br>
<br>
Could you try the test with the env OSG_GL_ERROR_CHECKING set to<br>
ONCE_PER_ATTRIBUTE, setting the env var to OSG_GL_ERROR_CHECKINGas<br>
your specified will not change the setting, so will default to<br>
ONCE_PER_FRAME.<br>

Hi Robert,<br>
<br>
Yes, indeed, that's the OpenGL error. I have build the same version on<br>
Windows (nvidia card) and no such error so I am not sure of course if it has<br>
to do with OSX or not.<br>
<br>
The last version that I checked was 3.5.4 and that one doesn't produce the<br>
errors. Indeed, I tested it explicitly because of the VAO changes.<br>
<br>
Later, I will produce more results and post them.<br>
<br>

Hi Raymond,<br>
<br>
Thanks for the logs, unfortunately the debug logs actually make it<br>
more difficult to spot the actual errors. The only error I spotted<br>
was:<br>
<br>
Warning: detected OpenGL error 'invalid operation' at after<br>
RenderBin::draw(..)<br>
<br>
Is this the error you are thinking of?<br>
<br>
Could you set the OSG_NOTIFY_LEVEL back to NOTICE and the env<br>
OSG_GL_ERROR_CHECKING env var to ONCE_PER_ATTRIBUTE<br>
<br>
This hopefully will enable us to home in a bit more closely to what<br>
might be causing the GL error.<br>
<br>
Another useful bit of information is the last OSG version that doesn't<br>
report the above error on our system. It could be that the cause of<br>
the GL error precedes the VAO work.<br>
<br>
Cheers,<br>
Robert.<br>

Hi Robert,<br>
<br>
I just tried a build from this mornings git master on my Mac book (up to<br>
date OSX and dependencies) and both the default and VAO paths result in<br>
OpenGL errors. I have attached 2 (stripped) logs which I created after I<br>
increased the notify level. Rendering results of cow, cessna and some<br>
other<br>
models look ok.<br>
<br>
I was going to try gdebugger but that one is not available anymore?! If<br>
you<br>
have some hints to produce more info I am happy to test some more.<br>
<br>
Cheers<br>
Raymond<br>
