Hey Cow, first post ever.

So I've always loved using luma maps (often based off footage like smoke or water) to guide distortion and blur, I've used that kind of effect for years with great results.

Thing is, despite googling, I only know of two effects that can use maps - Displacement Map and Camera Lens Blur. (Potentially I could be forgetting something really obvious but off the top of my head that's all I got).

My question is - does anyone know of any besides these two? I'm trying to come up with some methods for really experimental stuff so don't hold back on anything just because it seems irrelevant. Anything that can be fed luma to produce a result!

Not exactly a problem but desperate for suggestions, any help would be hugely appreciated :)

Reel Smart Motion Blur uses maps for vectors (speed and direction) using the R and G channels for the vectors and A to indicate areas of motion (B is empty).

You can use maps with expressions you yourself write using the method sampleImage()

Also, there is the old PixelBender, and while the official plug in was discontinued, there IS this workaround at AEscripts 9I have not tried it yet):

https://aescripts.com/pixel-bender-accelerator/

And the PixelBender toolkit is still available here:

With Pixel Bender you can pretty much do anything. However it is SLOW (not multi-threaded and not GPU accelerated) although the third party plugin is supposed to fix all that.

If you're into plugins, you can control 3D displacement in Freeform Pro, Mir, Form, etc. with luma maps.

CC GLASS is basically the same as the displacement map except for it also has some shine and reflective settings on top..And the wave generator..kinda uses it
