Hi Selman Abi, Firsty if you have textures in your hand seperatly you can use this code to send textures in uniform variable,
// Create a texture object osg::Texture2D * normal = new osg::Texture2D; normal->setImage( osgDB::readImageFile( "XXX" ) ); normal->setWrap( osg::Texture2D::WRAP_S, osg::Texture2D::REPEAT ); normal->setWrap( osg::Texture2D::WRAP_T, osg::Texture2D::REPEAT ); normal->setResizeNonPowerOfTwoHint( false ); normal->setMaxAnisotropy( 8.0f ); // Set up the shader stateset, geode is your target model which shader operaion will be implemented osg::StateSet * stateset = geode->getOrCreateStateSet(); stateset->setTextureAttribute( BASE_TEX_UNIT, normal ); // Them send this texture unit which normal texture already set. baseMap is uniform variable which you will use in your vertex or fragment shader. stateset->addUniform( new osg::Uniform( "baseMap", BASE_TEX_UNIT ) ); Sending a texture to shader composes of this 3 steps. If you haven't texture names and locations readymade, you may use 2 ways which I know to get them. Firstly you can write texture visitors, and you can traverse the texture nodes to get the textures information. I haven't try this but it could work for you :) Second you can convert your ive models to osg by osgconv and then you can get the texture names by using only notepad. Hope this helps.
