having trouble figuring this one out. see the following playground reference http://www.babylonjs-playground.com/#1KUECA#1
you should see a cube that should have a red overlay.
If you don't see the red overlay, then comment out the "var grassTex = " line and run it again.
can't figure out why the texture constructor is interfering with the overlay in all of my test scenarios.
the causal factor seems to be the procedural texture constructor, because when i comment that out, the overlay returns.
is this a bug or is something else going on here?
