tomhanks Posted May 26, 2010 Share Posted May 26, 2010 (edited) I know I can use particles to emit smoke on DOPS using density attributes on POPs, thanks to Peter Quint tutorial videos, but How could I use geometry to send velocity information to my smoke fluid? I would like to use geometry point normals to control velocity on my smoke fluids on DOPS, is it possible? Thanks, sorry the bad English.

Feed a Sop Geometry DOP to bring in your geo into the second input of your field force DOP. On your field force DOP, set the force attribute parameter to N. You may also need to turn up the scale force quite a bit depending on the length of your point Normals.

tomhanks Posted May 27, 2010 Author Share Posted May 27, 2010 (edited) That is what I was looking for! Thank you very much! Edited May 27, 2010 by tomhanks Quote Link to comment Share on other sites More sharing options...
