When will this get merged? :D

It wont, unfortunately.

It has to be updated, when either DX11 goes in or PBS. Actually, it might be enough with the deferred shading feature that went in a while a go, but I haven't checked up on that.

Edit:

A little background, the issue was that too much information was lost between texture passes, since the passes used RGB for color and A for blending info, there wasn't a channel free for the heightmap info.
