So, here's my entry. Full size version is in my gallery. And everyone else who want to participate and haven't handed in yet, remember that to participate, you do need to hand in your image in this thread before the deadline (end of February), don't forget.

Like this then:

Something like this?

There is a copy button in the effects dialog. Just highlight the effects to copy and hit it.

I think this is close to the final appearance for this map. Maybe some tweaks, but other than that, the map is done.

Image below shows map with a grid.

I am using a wall mask which is just the background multipolied with the floor to hide the grid and effects outside the walls. I am also using the color key effect both to break open the central room, as well as hiding the grid over the canyon.

This is intentionally a small place, but for a bigger map, pretend those are 10 foot squares instead of 5.
