You are all very kind! Probably will use Vue for the contest renderosity cover which ends 5 october, Winter memory, Vue should be very good at this, as winter recall snow, and snow recall landscape ;=) I also suggest all of Vue users to participate to this contest... Not enough time to do this with C4D... I'm just a beginner trying to place a ball and to render it (Ahahah!). As you see I'm still here, and I still use Vue ;=) Yves
