Hey! Guys! I was learning UE4 engine and got this strange problem. It just looks like not being built. And it is not about the textures, since I had tried to change the textures and found useless. It remains very white. Also I have tried to change normal light and found it is fine. Please help me!

If you’re still looking for a solution, you should check the lightmaps of this object and mabye try to increase the lightmap resolution of the wall in the details panel.
