Hello guys, I have a problem, I am creating an architectural scene, I give creating basic blueprints, lights, doors and sound, plus the objects I’m using to do the blueprints are getting the burst textures, getting clros, I compile and It remains so.
Can you please explain what this is?
I had the same problem but it was just a trial to see a thing on a blueprint and I didn’t make any further investigation (but sooner or later I will have to!)
If anyone has explanations I’ll appreciate too, and if I’ll disover anything I’ll come back! 
The image on the left is in the mesh editor that has almost no lighting. When it is in the world it draws from some lighting volume caches to decide its brightness. Set the object to static and build lighting to see the true brightness. Or place the regular static mesh next to the Blueprint version in the world if that is the difference you are trying to point out.
Mesh editor window <> In the world - is not a fair comparison.
