Hi, I've done all the tests, and they are all ok.
May the problem comes from the depth buffer attachment ? When I use : Code: p_camera->attach(osg::Camera::COLOR_BUFFER, p_renderTextureColor, 0, 0, false, 4, 4); p_camera->attach(osg::Camera::DEPTH_BUFFER, p_renderTextureDepth, 0, 0, false, 4, 4); or : p_camera->attach(osg::Camera::COLOR_BUFFER, p_renderTextureColor, 0, 0, false, 4, 4); p_camera->attach(osg::Camera::DEPTH_BUFFER, p_renderTextureDepth); There is black screen, but if I don't attach depth buffer, I got something rendered and no "Warning: detected OpenGL error 'invalid operation' at after RenderBin::draw(..)" errors in the console. Here is how I create my textures : Code: // Main color texture p_renderTextureColor = new osg::Texture2D(); p_renderTextureColor->setTextureSize(p_osgViewport->width(), p_osgViewport->height()); p_renderTextureColor->setInternalFormat(GL_RGBA32F_ARB); p_renderTextureColor->setSourceFormat(GL_RGBA); p_renderTextureColor->setSourceType(GL_FLOAT); p_renderTextureColor->setFilter(osg::Texture2D::MIN_FILTER, osg::Texture2D::LINEAR); p_renderTextureColor->setFilter(osg::Texture2D::MAG_FILTER, osg::Texture2D::LINEAR); p_renderTextureColor->setWrap(osg::Texture::WRAP_S, osg::Texture::CLAMP_TO_EDGE); p_renderTextureColor->setWrap(osg::Texture::WRAP_T, osg::Texture::CLAMP_TO_EDGE); p_renderTextureColor->setDataVariance(osg::Object::DYNAMIC); p_renderTextureColor->setUseHardwareMipMapGeneration(false); p_renderTextureColor->setResizeNonPowerOfTwoHint(false); // Main depth texture p_renderTextureDepth = new osg::Texture2D(); p_renderTextureDepth->setTextureSize(p_osgViewport->width(), p_osgViewport->height()); p_renderTextureDepth->setSourceFormat(GL_DEPTH_COMPONENT); p_renderTextureDepth->setSourceType(GL_FLOAT); p_renderTextureDepth->setInternalFormat(GL_DEPTH_COMPONENT32F); p_renderTextureDepth->setFilter(osg::Texture2D::MIN_FILTER, osg::Texture2D::LINEAR); p_renderTextureDepth->setFilter(osg::Texture2D::MAG_FILTER, osg::Texture2D::LINEAR); p_renderTextureDepth->setWrap(osg::Texture::WRAP_S, osg::Texture::CLAMP_TO_EDGE); p_renderTextureDepth->setWrap(osg::Texture::WRAP_T, osg::Texture::CLAMP_TO_EDGE); p_renderTextureDepth->setDataVariance(osg::Object::DYNAMIC); p_renderTextureDepth->setUseHardwareMipMapGeneration(false); p_renderTextureDepth->setResizeNonPowerOfTwoHint(false); Thank you!
