Why is the shadow mirrored like that?

[ftlcgi]

I’m getting this mirrored shadows on Cycles
Only when the sun has an angle, if the light comes from the top there’s no visible problem
I remember i’ve had this issue before but i don’t remember how i fixed it

I’m using symmetrical texture, if there’s no texture applied the lighning looks fine

Have you checked yr model for flipped normals?

[ftlcgi]

yes, that was my guess to

[ftlcgi]

I fink this is the problem, this is how the material is setup, i found that the normals might not be tangent, if i set anything other than tangent the problem is fixed

Your normal map is set to sRGB, and needs to be noncolor or normal.

that was it, thank you very much!
