Hi Anders,
I remenber having such a problem with CEGUI and multitexturing, here is my
drawImplementation which works fine now :
void CEGUIDrawable::drawImplementation(osg::RenderInfo& renderInfo) const
{
osg::State *state = renderInfo.getState();
if (state->getContextID() != _activeContextID)
{
return;
}
state->setActiveTextureUnit(0);
state->setClientActiveTextureUnit(0);
CEGUI::System::getSingleton().renderGUI();
state->checkGLErrors("CEGUIDrawable::drawImplementation");
}
But my problem was just CEGUI textures going all white when looking to a
multitextured object, so maybe you have a new one. :)
Good luck !

Hi all (again).
Now to another issue.
I have an implementation of a CEGUI integration into OSG.
It has been working just fine, up until where I have a multitextured
Spider (rendered using ReplicantBody) in the scene.
As far as I know and can see, ReplicantBody does not set any states
explicitly outside a StateSet.
The same
Now Im not blaiming the spider for the problem, its just something
with it that messes up the CE gui drawing.
It disappear from the screen, until there is something rendered using
osgText, then it pops back into the display!
It seems that something in the state is leaking? from osgText that
makes it possible to render the CEgui drawable
This is what happens:
1. Render CEGUI only -> ok
2. Render spider, cegui disappears, if spider is culled, cegui does
not come back!
3. add text to scene ->cegui comes back
4 remove text -> cegui disappears
CEGUI is rendered with the stateset:
osg::StateSet* stateset = geode->getOrCreateStateSet();
stateset->setMode(GL_DEPTH_TEST,osg::StateAttribute::OVERRIDE |
osg::StateAttribute::OFF);
stateset->setRenderingHint(osg::StateSet::TRANSPARENT_BIN);
stateset->setRenderBinDetails(100,"RenderBin");
stateset->setMode(GL_BLEND,osg::StateAttribute::OVERRIDE
|osg::StateAttribute::ON);
stateset->setTextureMode(0, GL_TEXTURE_2D,
osg::StateAttribute::OVERRIDE |osg::StateAttribute::ON);
stateset->setMode(GL_LIGHTING,osg::StateAttribute::OVERRIDE
|osg::StateAttribute::OFF);
And in CEGUI:drawable() Im using the same state settings as in the
osgcegui example:
renderInfo.getState()->setActiveTextureUnit(0);
renderInfo.getState()->disableAllVertexArrays();
m_ui->getSingletonPtr()->renderGUI();
Replicantbody (the spider) is using the state:
submesh_state_set->setTextureAttribute(map_id, texture);
submesh_state_set->setTextureMode(map_id, GL_TEXTURE_2D,
osg::StateAttribute::ON);
submesh_state_set->setMode(GL_TEXTURE_COORD_ARRAY,
osg::StateAttribute::ON);
Im guessing that one of the drawables (ReplicantBody, CEGUI) is
leaking/missing a StateSet setting.
But whats puzzling me is that osgText seems to leave something behind
that enables the drawing of CEGUI again...
So with osgText everything works.
Before digging into the dirt, Is there something here that ring a bell?
