That did the trick, thanks,

Rodolfo,
You probably need to set a different texture unit for each overlay; see
OverlayNode::setOverlayTextureUnit(2) for the second overlay node. Just
a guess.. -gw

Hello,
This may be a silly question, but is it possible to have more than one
OverlayNode in a scene? I ran a quick test using osganimate.cpp and I
get strange results (see JPEG). I would expect to see two planes, each
one projected to a different base. Instead, I get two planes, but with
one plane projected to both bases (and no projection for the other one).
By having 2 overlayNodes in my application, I can have the ability to
"highlight" one node but not the other.
My main changes to osganimate are:
osgSim::OverlayNode* overlayNode = new
osgSim::OverlayNode(technique);
overlayNode->setContinuousUpdate(true);
overlayNode->setOverlaySubgraph(movingModel);
overlayNode->setOverlayBaseHeight(baseHeight-0.01);
overlayNode->addChild(baseModel);
root->addChild(overlayNode);
osgSim::OverlayNode* overlayNode2 = new
osgSim::OverlayNode(technique);
overlayNode2->setContinuousUpdate(true);
overlayNode2->setOverlaySubgraph(movingModel2);
overlayNode2->setOverlayBaseHeight(baseHeight-0.01);
overlayNode2->addChild(baseModel2);
root->addChild(overlayNode2);
Am I missing something in the code? I am using osg2.6.0 with WindowsXP
SP3, thanks,
