Hi there, Why the cube has a strange projection on the ground when I change the Z of the ground less than 0 such as -0.9?

It's none of business of the ground, Just the cube seems to render on the Z=0?
And you are right, the sub-images of sprite draw step by step. (I scribbles some pattern in the sp_cube) 
This is the one image sprite. And the projection on the ground rotates automatically, although making the rotation of the cube self fixed.
Try turning off the objects visibility. Fauxton automatically draws models, so the image that is being drawn is more than likely the default drawing done by GM.
