Hi everyone,

I'm using a tool called BSP Factory to create 3d maps in. It uses the YAL lightmapper, and as you can see from the pictures below, shadows don't start from the right point, and light leaks through the geometry.

In this example, the light behind the wall somehow leaks through:

In this shot, the shadow of the box does not start at the base of the object:

Any ideas why this is? I believe the program uses the bleeding-edge fix that sswift made a couple of weeks ago, but it isn't using the final code that was added to the code archives.
Thanks!
