Hi,
I guess answer to main question would be go ahead and add this.
Okay, I just wanted to make sure they are not left out intentionally.
But I just want to write about something else here. If you attach
Texture2DMultisample to Camera you would want to leave the number of
samples and color samples at 0. Thats because these params are used to
set up rendering to multisampled Renderbuffer objects and in post step
that Renderbuffer is copied to attached texture. If you set
Texture2DMultisample and additionaly set numbers of samples in attach
it will do rendering to Renderbuffer and then will copy the result to
your Texture2DMultisample attachment. I guess its not what you are after.
That is strange. In this case I need some explanation. I want to render
several multisampled color attachments and resolve them in later passes.
In this case I create a multisampled color texture and attach it to the
camera. In consecutive passes I rebind those textures as input and
resolve them there. If I leave the colorsamples and sample count at the
FBO I get a FRAMEBUFFER_ATTACHMENT_INCOMPLETE error for the first pass.
Setting them solved the problem and I got a correct rendering.
So what is the correct thing to do here?
You mentioned a copy. I always thought binding a texture to a FBO and
reusing it later in another FBO will not copy it, so I'm quite puzzled.
Am I'm doing something fundamentally wrong here?

Hi,
maybe this seems like s stupid question but why does
osg::Texture2DMultisample does not have a getNumSamples() function?
This might come in handy if, like in my case, a texture is passed
around for MRT binding (camera->attach), to determine the number
of samples for the attach function.
Would it be okay to add the get function?
cheers
Sebastian
