<br>
I've a Geometry (which is a wall) and I want to put two textures on it. A part with a first texture and a second part with a  second texture.<br>
<br>
I wrote the code above :<br>
<br>
Code:<br>
<br>
    //Texture 1<br>
    geom->setTexCoordArray(0, level->texcoords.get());<br>
    {<br>
      osg::ref_ptr<osg::Texture2D> texture = new osg::Texture2D;<br>
      osg::ref_ptr<osg::Image> image = osgDB::readImageFile("media/textures/stone_3_2048x2048.jpg");<br>
      texture->setImage(image);<br>
      texture->setUnRefImageDataAfterApply(true);<br>
      level->getOrCreateStateSet()->setTextureAttributeAndModes(0, texture);<br>
    }<br>
    //Texture 2<br>
    geom->setTexCoordArray(1, level->texcoords2.get());<br>
    {<br>
      osg::ref_ptr<osg::Texture2D> texture = new osg::Texture2D;<br>
      osg::ref_ptr<osg::Image> image = osgDB::readImageFile("media/textures/Metal_seamless2_ch16.jpg");<br>
      texture->setImage(image);<br>
      texture->setUnRefImageDataAfterApply(true);<br>
      level->getOrCreateStateSet()->setTextureAttributeAndModes(1, texture);<br>
    }<br>
<br>
<br>
<br>
<br>
However the wall appears completely black (no textures).<br>
<br>
If I comment the "Texture 2" block, the part of the wall with the first texture is displayed correctly. And if I comment the "Texture 1" block the part of the wall with the second texture is displayed correctly.<br>
<br>
I am missing something?<br>
<br>
Thank you,<br>
Florian<br>
