what is happeneing to my model

Hi, I useing 3DS MAX build model and UV ( any model give two UV, one a map channel and the other as Lightmap Index), Import UE give material, but model display error in last build scene, why? plz

Hey, Since you made your own Lightmap UV, did you disable “auto-generate Lightmap UV” in the import settings? If not it will make its own still and ignore yours.

Hi Daniel, I already disable “auto-generate Lightmap UV” in the import step… THX
