[osg-users] Multiple Render Targets & Multisampling

As far I understand, what you are saying is that as soon as you enable
on the FBOs you can not use the multiple render targets. All targets show the
same thing as the first one.
But this is not the case when you dont use a multisampled FBO.
I had the exact same problem and dropped the efford to find a solution as soon
I found that probably something inside osg was the culprit. All my pure OpenGL
examples were running fine.
What does OSGPPU do to handle multisampled FBOs?

Subject: [osg-users] Multiple Render Targets & Multisampling
Has anyone tried to do any advanced* multisampled post effect using osg?
If yes, I would like to know the "best osg path" to achieve this.
*deferred rendered for example
I have tried to attach a texture to a camera along with the multipleSamples and
This works ONLY when i have one rendertarget. In all other cases in the final
i see only the first (and not the 2nd 3rd etc ) render target. The other render
targets are not black, but they appear overwritten with the contents of the
first render target.
On the other hand i see the osgfpdepth example and it has a completely different
approach to the subject, almost handling manually fbos and rendertargets.
I tried searching on the mailing list for this subject, but almost all
discussions seem to stop without a final result at about 2 years ago.
Tnx for your time,
