Map for liquify? (like Displace filter)

[Klobrillenmann]

Hello everyone,

is there a way to load a kind of a masking / strength map in the Liquify Persona?
I tried to find a way to load a map in Liquify like it´s possible for the Displace filter.

I don´t mean to load a mesh but an image based map.

best regards

Interesting question, but unfortunately there is no such way. 

Out of curiosity are you talking about a height map or something similar?

Do you have any examples of the effect you are after?

It would be an excellent request option and you can make that suggestion here: https://forum.affinity.serif.com/index.php?/forum/55-feedback-for-affinity-photo-on-desktop/

I don´t mean a height map but more a distortion map, if this is the right term here.

In the provided example I used the Displace filter to distort a logo according to crinkled paper.
The map for the Displace filter is taken from a smoothed out version of the background, which can be hidden after usage.
I regularly use this technique to distort shadows I apply on surfaces or on the ground.

This looks somehow convincing on first glance but the truth is, I have no control over the direction pixels are shifted like I could do in the Liquify Persona.

A combination of the mentioned techniques would lead to liquification with a "mask" or a "map" which controls the amount of distortion I apply to an area with a brush stroke.
Then I would love to shift areas under bright parts of a liquify map/mask in a direction which makes sense together with the background. Areas under dark parts of a map would be shifted in the perpendicular direction.
