I didn't use a whole lot of custom resources in RtM actually, just the house sets, the stairs I made, and the railway set you made. To be fair, the grid is also clearly visible in King's Field 1-3, so I guess you can't expect too much, especially considering KF was among the first fully 3D games during it's time. I've got to say though, SOM has a really robust lighting engine for 2000 standards.
