LibGDX Generating a png from a model - libgdx

Question

The title pretty much say it all, I need to get a image from a Model is this posible? I searched for this and found nothing.
Solution thanks to #retodaredevil
FrameBuffer fbo = new FrameBuffer(Pixmap.Format.RGBA4444, screenWidth, screenHeight, true);
ModelBatch batch = new ModelBatch();
fbo.begin(); // make fbo the current buffer
Gdx.gl.glViewport(0, 0,screenWidth, screenHeight);
Gdx.gl.glClear(GL_COLOR_BUFFER_BIT | GL20.GL_DEPTH_BUFFER_BIT);
batch.begin(camera);
batch.render(instance, environment);
batch.end();
try{
FileHandle fh = new FileHandle(output);
Pixmap pixmap = ScreenUtils.getFrameBufferPixmap(0,0,screenWidth,screenHeight);
PixmapIO.writePNG(fh, pixmap);
pixmap.dispose();
}catch (Exception e){
e.printStackTrace();
}
fbo.end(); // Now you can draw on the display again
batch.dispose();
fbo.dispose();

From what I understand, we'll have to use two different tutorials
https://github.com/mattdesl/lwjgl-basics/wiki/FrameBufferObjects
https://xoppa.github.io/blog/basic-3d-using-libgdx/ (You're probably already familiar with this)
FrameBuffer fbo = new FrameBuffer(Pixmap.Format.RGBA4444, width, height, hasDepth);
// I've never used a FrameBuffer before so you may have to play around with constructor parameters
ModelBatch batch = // your ModelBatch initialization here
fbo.begin(); // make fbo the current buffer
glClearColor(0f, 0f, 0f, 1f);
glClear(GL_COLOR_BUFFER_BIT);
batch.resize(fbo.getWidth(), fbo.getHeight());
batch.begin();
batch.render(modelInstance, environment);
batch.end();
fbo.end(); // Now you can draw on the display again
// If you want to, you can resize your batch and use it to draw on the display
batch.resize(Display.getWidth(), Display.getHeight());
Once you do whatever you need to do to your FrameBuffer, you can get the texture
fbo.getTexture();
EDIT: That method doesn't exist, look at OP's question for solution
EDIT 2: FrameBuffer does actually have a method called getColorBufferTexture()
For saving a texture, look at https://www.badlogicgames.com/forum/viewtopic.php?p=8358#p8358 or https://www.badlogicgames.com/forum/viewtopic.php?t=5686
I used this to get one of the links: Libgdx save SpriteBatch in a texture everything else I duckduckgoed
If something doesn't work let me know and I can try to look around more.
