Max Schwugier Posted December 12, 2021 Share Posted December 12, 2021 Hi everyone, ive been using Houdini now for a few years and i absolutely love the power and the workflow with it but i am currently facing a problem which i cannot solve. the Orientation of my Grains are flipping and if I scatter stones on it, they are fliipping too. to visualize the Problem i copied grids on the grains. (check video below) I mean i could give it a straight up vector so nothing is flipping anymore but i want them accuratly rotate on the ground. In the Video you see grains on the ground and they should roll over the floor with proper rotations like marbles roll over a floor. pls help, i can not get my head round this... Thanks in advance!
