revelationsr Posted December 14, 2015 Share Posted December 14, 2015 Hello there. I have been playing around with a bit of smoke effects for a shot. I sort of have it about 80% of the way there. The only thing I am really missing out is the get the smoke to become wider the older it becomes. In Maya it is diffusion. I added the gas diffuse onto my solver but it does not seem to have the effect I was hoping for. Unlike the gas wind the diffuse has an input option. Am I on the right track or am I way off. O yes. Also I would like to create a layered wind effect. Less wond close to the ground and more up in the atmosphere. Any ideas on that?

Value91 Posted December 14, 2015 Share Posted December 14, 2015 Here is the approach for your wind Quote Link to comment Share on other sites More sharing options...
Annon Posted December 14, 2015 Share Posted December 14, 2015 Diffusion is going to blur your density values, you want divergence... As for wind, you can either source velocity that is stronger the higher up it gets, or create one on the fly in the solver that is influenced by temperature, so the cooler it get's the more influence of wind it's going to get. Creating your source in SOPs is obviously the easiest option here if you don't know DOPs that well. Quote Link to comment Share on other sites More sharing options...
revelationsr Posted December 14, 2015 Author Share Posted December 14, 2015 Great thank you. I will have a look now. As well as try divergence. Cheers Quote Link to comment Share on other sites More sharing options...
Annon Posted December 16, 2015 Share Posted December 16, 2015 The OP asked me to put together a scene, so here it is. It's not made to look particularly good, only to demonstrate how you would put this together.

revelationsr Posted December 16, 2015 Author Share Posted December 16, 2015 Awesome man. I will be having a look at it now. Cheers Quote Link to comment Share on other sites More sharing options...
