Hmm, okay. As your referenced post mentions that the polygon group can't be changed after its compiled or rendered, I could in theory try;
Load my 'master' plane
Clone it (create 'split' Object)
Use Polygon Manager to re-assign uv coords
Pass the 'split' object in to the world.
Once done with the 'split' object, remove it and repeat the above process for the new size tiles?
Btw: Did you mean the plane.compile(false, false, true, false, Config.glBatchSize);
method, not build(false)
?
If this sounds correct, I think I'll need a bit of experimentation to see if there is any performance gain compared to just building new objects on Android...
