Hi,
Since the change I suggest is very small from what JP has implemented I
don't submit files here just the differences:
I removed getDrawBuffers and setDrawBuffers from the Camera.cpp / h
In RenderStage the changes are as follows:
RanderStage //.h
Added vector of GLEnum named _drawBuffers.

Hello,
In continue to what I said before, I don't believe it's possible to
change the subgraphs MRT definitions, since all the subgraph under the
camera renders to the camera attachments. So if the camera is using MRT,
then all the subgraph is rendered MRT.
The differences

I'm sure you will see that there is no magic to my current

Can we not just do it when COLOR_BUFFER1 upwards are enabled?
Problem is that enabling MRT with just COLOR_BUFFER0 and then using

Hi All,
I've just merged J.P changes to RenderStage to add support for glDrawBuffers
in conjunction with my tweak to osg::Camera::COLOR_BUFFER0. J.P's
osgmultiplerendertargets example is also now checked into SVN.

is anyone looking at this, or should I assume no news is good news and

Hi J.P.
I am also using MRT, however completely without
osg::Camera.
However since I am working with FBOs directly I would
prefer to have something like an extra StateAttribute
or something which should setup the MRT. Or maybe the
setDrawBuffers as an extra method in the FBO code.
I think

I'm curious about the going for a custom StateAttribute for
DrawBuffers. In terms of encapsulation osg::Camera isn't a bad place
for it, as there is already lots of RTT support there already. If
there are cases when you want to enable/disable different combinations

Hi Robert, J.P.,
Of course the camera is a good place for it. However I
would also prefer to have it somewhere else, because I
am not always using cameras to make render to texture.
Ok, maybe I am the one who is using the FBOs and RTT
functionality out of the camera ;-)
Hmm, maybe I was to fast
