   Render to 3D Texture
  Hi,i try to render with a FBO into a 3D Texture without success. int layers = 128glGenFramebuffers(1, &this->framebufferObjectVolume);glBindFramebuffer(GL_FRAMEBUFFER, this->framebufferObjectVolume);    this->orthoProjection->startOrthoWithGlu();    for (int i = 0; i < layers; i++) {   glFramebufferTexture3D(GL_FRAMEBUFFER, GL_TEXTURE_3D, GL_COLOR_ATTACHMENT0+i, this->textureController->getTexture("tex3d")->getHandler(), 0, i);   glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);   drawFullscreenQuad();    } this->orthoProjection->endOrthoWithGlu();Can someone tell me what i do wrong? Thank youelement   
  I solved it. Was a stupid fault...wrong:glFramebufferTexture3D(GL_FRAMEBUFFER, GL_TEXTURE_3D, GL_COLOR_ATTACHMENT0+i, this->textureController->getTexture("tex3d")->getHandler(), 0, i);ok:glFramebufferTexture3D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_TEXTURE_3D, this->textureController->getTexture("tex3d")->getHandler(), 0, i);there was also a framebuffer exception. Don't forget to check for that.
