I want to place large, colored (red, blue, purple, ..) dots on the terrain that are visible in Sapphire to call attention to certain locations.
To that end, I tried using the Edit feature with the texture map.
The TX brush edit dialog calls for a climate, so I created a custom one called Marker. There, I created land types Red, Blue, Purple, ... with the appropriate color.
When I try to paint on the texture map with that brush, the area in question turns black. If I move the brush around a bit, some of the painted area looks like blue dots, while most is black.
If I then switch to the Attributes Map and paint with the same brush, I do indeed see a red dot. However, generating the texture map again yields the original texture, no red dot.
What is happening, and how can I paint colored dots on the texture map?
