Mirroring textures for animated fbx file imported from 3ds max

Hi All,

hope someone will be able to help me out.

i have a few models that i am importing from 3ds max in to unreal engine. some of them load perfectly with the textures in the correct place. others load without the textures which is also fine as i can re apply them except for one particular type of texture which is causing me massive headache.

all the models use mirrored textures which confuses me as to how some of them load perfectly and others just dont work.

is there something i should be doing from 3ds max when exporting? or is there just a simple function to mirror a texture in unreal?
