agelosc Posted February 21, 2018 Share Posted February 21, 2018 Hi, I'm trying to create a smoke effect where the smoke is getting slower and slower to the point that it almost stops advecting as it gets further away from the emittion. I still want the emitter to pump out in normal speed but I'm looking for a localised drag away from the emission. I've created a velocity field in sops and multipled it in with a source volume to get the smoke velocities to zero but it doesn't look good at all. I'm afraid that's as far as my knowledge of the gas dops go. Can you suggest any other way of going about this? Thanks. Quote Link to comment Share on other sites More sharing options...
violalyu Posted February 21, 2018 Share Posted February 21, 2018 Hi Agelos, you could try gas damp, you can check out the parameters and play with them, should be able to get that effect:) 1 Quote Link to comment Share on other sites More sharing options...

agelosc Posted February 27, 2018 Author Share Posted February 27, 2018 I ended up using both techniques, added a gad damp with a custom field for local control and also used a wrangle to push and pull because the drag was making the shape of the smoke too symetrical. It took a while to get the balance right but it worked so thank you all for your help, much appreciated. 1 Quote Link to comment Share on other sites More sharing options...
