How do I make a displacement modifier affect multiple objects?

Question

[![enter image description here][1]][1][![enter image description here][1]][1]I've ripped this model out of a game, a character that is made up of multiple objects . I want to 3d print it , but since its from a game it doesn't have detail in the mesh , but in a displacement map , but since I want to 3d print it the detail needs to be in the mesh . now the legs , body and arms are different objects but there uv wrapped on one texture.

The displacement map is just one image for arms , legs and body , but I need to have the displacement modifier treat arms , legs and body as one object . Why I cant just join the objects together using Ctrl + J ?

because the displacement map is made for the way that the objects are uv wrapped and joining them together would destroy the uv wrapp and thus make the displacement map useless.

Update:https: I put the original nrm file in as well

Consider sharing your .blend file (with the images used as textures packed into the file) so that others can inspect it. You can upload it at http://blend-exchange.giantcowfilms.com/ and then paste the resulting link as part of your question. — HISEROD, Jan 08 '21 at 18:29
Note:This is not finished I plan on ading clothes and posing it — gamefreakmilo, Jan 08 '21 at 20:26
The texture is still not in the blend. Before you upload you must pack the texture and save the file. — HISEROD, Jan 08 '21 at 21:24
I did at least I think... I'll just aply the texure to a default cube — gamefreakmilo, Jan 09 '21 at 13:02
You still need to pack it. The file location is currently set to //..\..\Downloads\Wii U - The Legend of Zelda Breath of the Wild - Link\link_skin_nrm_DISP.jpg Only your computer can access that location. — HISEROD, Jan 09 '21 at 16:55
In the upper left of image editor, there should be a dropdown labeled image. Click that and find the button that says "pack." — HISEROD, Jan 09 '21 at 17:07
Ok, idk what you're not getting here. That last link was a default scene. — HISEROD, Jan 09 '21 at 20:56
You're right. fsr the first download must've been corrupted. — HISEROD, Jan 09 '21 at 21:01
Ok, that one's good, but there are some issues with what you are trying to do. The displacement map isn't consistent across the fingers and around seams which would be a pain to fix. I think you would be better off using it as a bump map, which is what it was likely intended for. — HISEROD, Jan 09 '21 at 21:33
@gamefreakmilo please add any future new information such as images, updated blend, etc directly into the body of your question as an [edit]. You are always able to edit your posts. Please also read the [tour], there is some useful info there :) thanks — Timaroberts, Jan 09 '21 at 21:57
It originally was normal map . I read that you can't make those part of the mesh . if so please tell me how — gamefreakmilo, Jan 09 '21 at 22:00

The different parts of the body have different UV-Maps. As you can see in this image, when I join them, I get 3 UV-Maps (At the rights side)

You can solve this problem, when you Name them the same before mergin. Then you get this result:

Thanks I'll try that – gamefreakmilo Jan 10 '21 at 10:02
so put them in the same vertex group? I don't entirely understand what you mean. – gamefreakmilo Jan 10 '21 at 10:33
You name the Uv-maps the same before you merg them – user92785 Jan 10 '21 at 11:27
Under the shape keys (which are under the vertex goup) you find Uv-Maps – user92785 Jan 10 '21 at 11:28
It worked!!! Thanks a lot – gamefreakmilo Jan 10 '21 at 12:01

@HISEROD said the displacement map wasn't made to be a displacement map wich is true so I guess im going to have to somehow make the normal map a part of the mesh . the reason I didnt do that is because there is no documentation about that... I thought it was inpossible , but apperently it is so please tell me how – gamefreakmilo Jan 10 '21 at 12:22
