Yep, PHeMoX's right, i used a halfshphere with rtt. I think i'll lower sphere's curveness, that should do the trick

And thanks again for the positive comments, they really motivate me

And in case somebody wants to help me, i've got a kind of problem with ground aligning - none of the ways of matching angles of player and ground works for me - for example if a quaterpipe has pan like 0, 90, 180, 360, aligning is fine, but it pan is something like 45, the snapping seems inaccurate

I've got no idea what causes it
