Re: [osg-users] openGL error with osgEarth?

Akilan,
You are probably running out of texture units. In multitexture mode,
osgEarth uses one per layer. Try using multipass mode instead:

MapEngineProperties props;
props.layeringTechnique() = MapEngineProperties::LAYERING_MULTIPASS;
MapNode* node = new MapNode( map, props );

 Hi Jason,

 In fact, I create the map through program.What the program does is that as
 and when some new tif file arrives at particular folder which I am
 monitoring continuously thru callback, I add the file to the already created
 map. It works well for some 2-3 tile addition. When it goes beyond that it
 throws the openGL error. Have a look at my code. Is there any other way to
 do the same.

 relative path

Hi Akilan,

Can you post the earth files you are seeing errors on?  Perhaps you
are specifying more image layers than you have texture units.

 Hi,

 When I run some of my .earth files, I m getting warning saying,
 detected openGL error, invalid enumerator, after RenderBin::draw(,).
 I m not sure why this error is caused?
