Assets Blacks when import GLTF into Unreal

When I import a GLTF scene into Unreal, all the blocks are black, with no textures. Any solution for this? Thanks.

which UE version?
Can you share the gltf model with us?

are you using gltf runtime plugin?

Any block I export from max, in gltf, to Unreal, turns black. I tested it in Unreal 5.3, 5.4.4 and Max23 and Max24. No sucess

yes
