Help! Why after import a file it makes all the scene too much brighter?

Hello, my name is Daniel and I am having a new trouble when importing files into my scene.

I am working with Unreal 4.24.3 and 3dsMax with Datasmith. When I had Unreal 4.21 everithing was fine, but now in 4.24.3 when I import a datasmith file it makes all my scene brighter, almost white. I have turned off import lights, I just bring geometry, textures and materials.

I have tried everything I know, tried to import another file, activate lights, deactivate them… but nothing works, I have change the exposure of the ProcessVolume, but it’s fake because it makes me turn down too much the compensation and my material lights turn black so it doesnt works really.

If someone can help me I’d be really grateful!
