mic Posted February 4, 2009 Share Posted February 4, 2009 hello! please help me to create some not very difficgult effect. for example i have object which abrupt movement, and some dust (just points, for example, scattered on it) should fly away while this object shakes. how should i do this? at first approach - very simple: only grid and sphere on it we have, for example, grid is moving Y-axis with acceleration, suddenly and fast - how should sphere jump up on it? it always stay on the grid.. Thank you! Quote Link to comment Share on other sites More sharing options...
GallenWolf Posted February 4, 2009 Share Posted February 4, 2009 for example i have object which abrupt movement, and some dust (just points, for example, scattered on it) should fly away while this object shakes. how should i do this? Hmmm one way I can think of, is to calculate the velocity of the moving object, perhaps using the Trail sop. And then use the strength of v to emit particles. I may go a little further to take the dot product of the normal of the geo and the normalized velocity in order to only emit particles in the direction the geo is moving in. HTHs!
