#Big stack studio jet set go how to#
If anyone who has faster computer would care to make a tutorial on how to use Optical Flow for a ripple/wave effect as shown above, I'm curious about how it might look.

I could barely move my cursor without the "spinning beach ball" coming on for two minutes. It seems to be one of those FX (like Inlay Texture) which uses a lot of CPU and/or RAM (?) and makes my computer go very slow. I can't get the Optical Flow to work for a rippling/wavy effect. The Perlin Noise or the ripple glass texture (used with Displacement Mapping) worked for my purposes. I had it move across screen from right to left (using KeyFramer) then used it as Source layer in Displacement Mapping applied to the BG layer. This time I did not use Perlin Noise, I used a photo of an actual piece of ripple glass. Created the turbulence on it's own layer, then used the perlin noise turbulence as the Source in Displacement Mapping applied to a layer. I'm not good about doing that, so sometimes I achieve a good effect by trial & error, then if I have to reproduce the same effect six months late I forgot exactly how I did it. I'll try to remember to document each step I take. (the actual project I want to use this effect on is under NDA, so I can't show it, but I will make tests first, which are shareable. Thank you, thank you ! I had missed the step to set the turbulence layer to invisible (inactive). Since the turbulence layer is hidden, only its effects on the animation will be visible. Then, on a duplicate layer of the actual animation clip to be distorted, use Displacement Mapping (under Distortion)and set the Source as the turbulence layer that you created. The way I would approach it would be to first create the turbulence using perlin noise or plasma on its own layer.
