Static Mesh Blue Print Door

[dzemzmcdonalda]

Using Lumen won’t really fix your issue, it only hides it.

Lumen is basically a ray-tracer so if you use it, it doesn’t matter if the objects/shadows/lights are static or not, Lumen treats them in the same way.
However, this comes at a cost in performance (a very very high cost to be honest).

To fix this problem, you’ll need to use some dynamic lighting, just like RevOverDrive mentioned above:

The simple fact they are dynamic (moving parts) means that static lighting will not work on them.

You can see this by dragging in the mesh itself and rebuilding. The mesh will get the proper lighting because it’s a “Static” actor. The BP actor will not.

You’ll need a dynamic lighting source in scene and have the mesh cast and receive dynamic shadows.
