Photoshop: Displacement Filter Overhaul. Live preview of Displacement.

Please Adobe, take care about those ancient filters. After 20 years they should be updated...all of them.

Undo, and run it again with different percentages

With a Smart tFilter the undo-step would be unnecessary. 

I use Displace all the time, and it sure is a drag to run the filter, decide the effect is too much or too little, Undo, and run it again with different percentages, and have to select the file to use as a map again. And if the filter is updated, you should be able to use 16-bit maps as well.

Seems that this effect hasn't been updated since I first started using photoshop 10+ years ago.  Its very useful for texture artists but having to load in a psd without any real control seems very archaic now.  Could it not be updated with the after effects version which works great?  In after effects you can displace a layer from another layer within the document and set the displacement in x and y from different channels.  Would be a much more intuitive workflow

Thanks

Thiiiisssss. I'd also love to see a preview of what the Displacement filter is doing instead of guessing at my settings. So frustrating.

Also, can the displacement please resize with the image? When I resize my image or smart object (with a smart displacement filter applied) it does not retain the position of the displacement file. And I have to start over creating a new displacement psd.  Or is this a bug?

Well, first, let's merge with this topic : https://feedback.photoshop.com/photoshop_family/topics/update-photoshop-displace-effect

Or the map could be editable the way masks are. Its thumbnail could appear to the right of the mask thumbnail. (Granted, it would take some more realtime processing power; masks and blending modes do a 1-to-1 pixel operation for every x,y position, while this would be  a 1-pixel-to-multiple-pixels operation from the original image to the image warped by the displacement map.) Allowing it to be an editable smart object could be even better. (Heck, why can't masks be smart objects?) You could have a toolbar appear while its selected (with options like softness to smooth out discrete bump levels). It could be RGB, and on the toolbar you'd select which channel effected X displacement and which effected Y displacement.

Well, they might, if it was more powerful, flexible, and had live preview.
