Hi
Got a problem - created a poly (two triangles), used grass texture (transparent png) for it. When rotating camera up/down, black line sometimes appears at the top of "grass" poly. See http://prntscr.com/bajmq
 Is it a result of inproper texture mapping (maybe line is actually bottom row of grass texture?) or smth other.
Size of texture is 512*128, size of poly is 4*1.
How to make texture to fit this poly properly?

No, i actually mean setClamping() as enableClamping() is deprecated...anyway, both do the same thing.... ;)

You have to set some transparency by calling...setTransparency(0...x) on your grass objects. If the png contains an alpha channel, make sure to use the appropriate construtor or jPCT will ignore it and create it's own.

I'll test it. What if I make the background dark by myself?
the JPG rock texture looks good.
