Like you see on the image below there are weird shadows on my static mesh.
I exported the wall from Blender. I created a Lightmap and a UV Map.
If I put the mesh on the ground (Landscape, BSP, Static Mesh) there are these weird shadows…
Hope anyone of you can help me!
What is the lightmap resolution of the mesh? Also can you post a screenshot of the lightmap UV’s please?
Maybe its a problem with shadow acne, try to adjust the Shadow Bias value in your lightsource.
