title: libgdx decal dynamic text
body: <p>I'm working on 3D (2.5D) application in Libgdx.
  I've found Decals very useful for this purpose.</p>
  
  <p>In my app there should be layers, that contain dynamical text, now I'm wondering what is the best way to draw text via Decals.</p>
  
  <p>Currently my implementation is based on drawing BitmapFont to FBO, then I get FBO texture and bind it to Decal before DecalBatch.flush().</p>
  
  <p>I think that this is maybe not the most efficient way of doing this, but can't figure out better way.</p>
  
  <p>My app can contain large number of text "layers" placed into 3D world, so maybe drawing each BitmapFont to FBO, and binding FBO texture to Decal isn't the best approach.</p>
  
  <p>Do you guys have some better idea?
  What is the most efficient way of doing this?</p>
  
  <p>Tnx in advance!</p>
