Question Geometry behind other becomes sivible

Hello, I´m having one issue on my game for android.
The problem I have is that when an object that is compunds of two or more objects, the objects that they shouldn´t be visible they becomes visibles (i attached an image about my problem) when the player is at certian distance from them.
I have made a lot of tests (with different resolutions, quality settings, etc) but I haven´t succeded to solve the problem.
Someboy knows where come from the origin of the problem?
Thanks

 

How far is far?
Maybe change the clipping plane on the camera?

 

5 meters more or less.
I have the clipping planes of the camera near=0.01 and far= 1000.
The object is a character with clothes so the problem is that parts of the character behind the clothes becomes visible.

 

The origin would be z-fighting. Z-fighting - Wikipedia
The resolution? Could be several things.
An easy thing would be to increase the size of your outer geometry so it clips less with your inner geometry.

 

Thank you, I´ll try to increase the outer geometry if it works

 

Unfortunatelly increasing the size of the outer geometry didn´t work...

 

Do you use any custom shaders?
Also which unity version? Urp/hdrp/builtin?

 

Currently I use a shaders from urp graph and it´s a really simple the shader (difuse,normal and metallic). Also I tested the project with simple default Built in shaders when I started the project and it happened the same problem..
