The model is created using maya then loaded into directx. the problem is that all textures are mirrored when i loaded it into directx using fbx sdk 2018.1.1. When I load a random character model from internet, it is rendered ok. I cant find the problem???

My program:

Maya:

Are you sure that it's the textures and not the geometry that's being mirrored? It's kind of hard to tell the difference when your geometry is that symmetrical.

you are right geometry is mirrored. How can I fix that?

Usually when geometry is flipped, it's because of a handedness problem (i.e. left-handed data read into a right-handed 3D engine or vice versa). The standard fix is to flip the z coordinates at load-time, which may be an option that you need to set at some point in your asset pipeline. But you'll have to work out the details yourself, because I have no experience with Maya, fbx, or DirectX.

it's ok i fixed the problem. your answer lead me to the solution. thank you
