Create New Material from Image 2d

Hello to everyone,
I'm engineering student and I want to recreate damage concrete in beams and column.
Is there solution to create a new material 3D without Texture?
I have my default material that is concrete and I want to create cracks only in a part of beams like in photo posted.

Thanks for everyone help me!

 

Hi,
Yes it's possible - You could use decals. That way you could just stick a decal to a spot that has damage.
If you're not aware what decals are, they're just geometry objects that use a shader trick to make them look like they're on the surface. There's many decal solutions out there and HDRP for example has built-in decals, and you can get at least basic (quite ok) decals for free for built-in pipeline.

Btw, are you aware that your image links are broken? Might be a good idea to just upload the images to the post and use those, as they always work.

 

Thanks For Reply.
It's a good Solution but in my case isn't valid because i have a lot of elements in my scene and i looking for a quick solution to apply directly in all my element.
In the first image i try with your metod and this is result. This is my step: Beams dimension are 800x70, create a new image in paint 800x70 pixel and put this in new material that i have appy near my elents. (Another problem is that crack are 2d and in my case is 3d).
Then i try to apply directly in my elements and it isn't no good like you can see in beam above.
