I made the changes that you recommended, Sue, and it appears to work on-screen. I was able to move the light sources for the four stained glass windows on the sides of the church to a point where the lights look normal. Here's a screengrab.

But something weird is happening (which is why I had to do a screengrab instead of saving an image). Whenever I go use "save as" to create a JPG or PNG image of the map, it crashes during the first pass of rendering as soon as it reaches the "Lights - End" sheet. It does that regardless whether I am trying to save an image of the entire map or just a rectangular section of it.

I just did a test and turned off the RGB Matrix effect on the "Buildings Low" sheet, the first sheet to have that effect on it (on the assumption that if the problem was with the RGB Matrix, it would get through the "Buildings Low" before crashing). It still crashed at the "Lights - End" sheet. Then I did another test, turning off the "Wall Shadow, Point of Light Finalize" effect on the "Lights - End" sheet, and it was able to render a JPG correctly (except it's no longer night without that effect).

Hmmmm...?

Here's a look at it at night, with lights added. I experimented with adding a moon like Jeff B did with his contest entry, but it was creating weird banding effects that I couldn't resolve. Instead, I played with the Shadow-Transparency in the Global Sun settings.

Round 3! These fog symbols are scaled at x4.

Added a bit more to the haunted mansion and its environs, including populating the graveyard more and adding some low-hanging fog for atmosphere. I didn't want too much fog, but enough. Let me know whether it works. I can always add a transparency effect to soften it more. Of course, the real test of whether it works will be when I set it to be nighttime.

It's "spooky season," so I had to map something in honor of the season. I have a few other ideas, including a swamp witch's home (we'll see if I can pull off designing a swamp). But first, a haunted mansion on a hill overlooking a church and its appurtenant graveyard.

This is done mostly in Creepy Crypts, with buildings from Darklands City and CD3, and a few things brought in from Forest Trail (mostly the trees and the tower ruins for wells). The stained glass window reflections are from the Mike Schley monthlies. (Why, you may ask, are the reflections outside? The last thing I will do will be to play with the lighting to show that this is at night -- the lights are inside the church, shining out, rather than the other way around.)

Working on the environs first and then with tackle inside. Still have to finish populating the graveyard and
