Strange "Bubbles" on Walls

When i build my light i get strange “Bubble” like object on some of my walls (see screenshots) I only have 1 Directional Light, and 1 Point Light (one in each of the 2 rooms i have) I used the Box Brush to make the “Walls” and used the base wall texture. I tried if scaling down to the original box`s size did anything or altering the texture on the wall but no success.

Hey Pandabrain,

Would you mind providing some more information on how you have your lights set up in your scene. Usually a screenshot with the parameters or values of your light are sufficient.

It seems you have multiple overlapping brushes to comprise your walls?

If they are still BSP’s try converting them to Static Meshes and see if that changes anything.

Thanks,
