Hi, i try to render with a FBO into a 3D Texture without success.
int layers = 128
glGenFramebuffers(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 you element

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.
