VertexAlpha problem!!! Plzz help

Blitz3D Forums/Blitz3D Programming/VertexAlpha problem!!! Plzz help

The ground layer seems to be getting drawn in front of the hill at the part where another texture should be. I'm pretty sure this is down to the problem i described in my previous post.

I assume the area is supposed to be like this, based on the texture scale.
