Underwater distortion effect for cross-platform?

What's a good looking water effect in your opinion? Do you really need the distortion effect?
Apply the shader distortion effect only on PC and leave it out for Android and iOS? With some nice looking graphics you don't need the distortion effect I think.

I imagine there might be a really complicated (and possibly resource intensive) way to achieve this without shaders, but I'm not sure how. Shaders are probably your best bet, unfortunately.

For a particularly good underwater effect, I recommend the Clement one that you can get from the clickstore. I'm pretty sure it's in his Please login to see this link.. I use a customised/tweaked version of that in my underwater levels (You can see it in action in the video background of Please login to see this link.)

Didn't sparckman create a pretty cool tutorial for underwater stuff? Can't remember if it was cross platform though but it looked really nice

AFAIK Sparckman tutorial used perspective object and it's not cross platform .

A good way to achieve this is, to apply the shader in PC runtime using D3D9 and then run the application with the animation looping.

Take a video recording of the predefined area with a decent video recorder (ie: GeForce Experience) and crop it down. You can then throw it into your favourite editing software to do some frame skipping etc. and export it out as a GIF or AVI and then re-import into Fusion 2.5 as an active. If it's only a looped animation that is say 320x240 big, you can achieve this with an output of around 2mb, maybe 4-5mb uncompressed if you can do a quick loop.

Indeed, image animation could do the trick unless you need to move your character underwater, then it wouldn't work.
I'm not sure this can be done without shaders, gladly Fusion 3.0 will fix this.

I am fairly certain you will need shaders in order to accomplish this effect without actually animating the effect itself.

I know this is from 1 year ago. But i need to answer questions.
