Smoke animation with wave warp, problems with zoom out

Report · Aug 10, 2018

Hey everyone!

I am animating a zoom out from one single cimney to a whole skyline with a lot of smoke (a preview underneath)

I have built the smoke with 3 shape layers to which I have added wave warp - works quite nice for that purpose. HOWEVER, I have troubles with the zoom out:

WhenI turn on 'Continuously Rasterize' for the Comp in which is the smoke I have the trouble that the wavelength of the smoke is smalled down during the zoom out:

That does not look nice. But when I turn of 'Continous Rasterize' - the shape of the smoke is alright, but of course, the line quality is horrible!

Does anyone have an idea how I can get rid of that issue???

Best regards and cheers from Holland!!

Nothing wrong here. That's just how pixel-based effects work. You need to think of something else like actually animating the wavelength and amplitude or using a whole different method alltogether.

Thanks for your quick answer!!

Okay right, then I think I have not understood what is actually going on there I have a subcomposition for the smoke, i am happy with the shape, now i want to zoom in (or actually out) in another composition - there i have no extra effects or keyframes added to the subcomp ... so why is its shape changing? 😕

then i should maybe put it in the same composition and put some keyframes to wavelength and frequency and tweak around?

otherwise do you possibly know an adequate effect for this purpose.. which is not influenced in its shape by zooming?

cheers man!!
