I cannot get the mouse-thing-problem to happen here. What version of A6 are you all using??

Okay.... I made some changes to the build. Just so you could digest some things.
1). It only blends the one texture, using 1 alphamap.
2). I resized the alphamap to 64x64 instead on 256x256 to save mem.
3). I resized the textures to 128x128 to save mem.
4). I resized the skycube texture to 128 height, to save mem.

reduced texture sizes = reduced filesize (1.79 MB)

Really curious on the mouse thing!
