How does Displacement work?
on Jan 17, 2012 at 1:26:17 am

Hi. I am trying to make a fan film for the video game Portal, and I have come across a problem while trying to recreate the effect of a portal opening. As a portal opens the surface its on distorts in a simple circle around it, kind of a shockwave of sorts. I have tried using the "displace" filter and an animated donut shape but it doesnt seem to be working. I have have searched all over youtube for a tutorial on how to use the "displace" filter but it doesnt seem to work for me. I would really appreciate it if someone would help me out with this effect or at least teach me how the displace filter works. Thanks!

Try the Ripple or Ring filters instead. You may need to keyframe them.

That makes sense. I didnt think of that. I'll try that out.
is there a way to make the ripple look like it is at an angle? for instance, if it was on the ground.

I just tried ripple and it didnt work, and circles did something completely different i tried bulge and bump distortion but their's no way to chance the shape of the distortion to make it an oval

I think that displace should work, i just dont know how to use it
Thanks
