How to scale up the smoke domain without affecting the resolution of the smoke?

Hi,

I’m trying to create smoke in a scene, where the domain has to be as wide as the field of view, because I need it to be blown across by a wind force field. Also the smoke emitter is in a car, that is set to collision. I want the smoke to exit trough the windows. I got it right with a relatively small domain. But when I scale it up, the smoke gets clunky and lo-res and it doesn’t fit trough the windows anymore. So it’s actually a big, grey, wobbling chunk of ugly looking smoke inside the car.

I’ve looked up several threads and tuts, but nothing seems to do the trick. No matter if I do the scaling in object mode or alter the domain in edit mode. Nothing makes a difference. I tried ‘applying the scale’ even though I do not exactly no, what that does. But that didn’t help either. I know cranking up the resolution of the smoke would provide more detail, but I end up with insane bake and render times.

I’m on version 2.78 and will try this in 2.79.

Thanks for the help.

There is no miracle. If you can’t increase resolution setting, you can’t expect required quality.
So, you have to cheat.
Don’t use smoke simulation for the whole frame.
Use it to create a stock-shot useable for compositing. Use particles instead. Use a mesh …
