Maybe make the grass a lot darker however, this hurts my eyes.
Thanks Rune
Update: Finished, Not exactly the same as the video,
Track is same shape though, But not getting paid for this,and it felt incomplete with an open end so sorry but it feels more like a finished mod now.
I know you did not order rocks also but to make a green block look like a natural surface you need something to contrast against to form the illusion of a hill or field. also in any competition you need a point to aim for thats my excuse for a trophy :P.
Sorry I strayed from the brief but I hope you like it all the same.
Also after reading your previous question again I think I misunderstood,
The ball will roll of its own accord, I just put uke there so you could animate him to give the impression that he pushed it.
