1. What did you do?

Recently been playing the "Ribbon world" map preset where map height is limited to only 128 tiles,
first planet I landed on was Vulcanus, where I started placing bricks along the edge of the map.

2. What happened?

I noticed that there was a brown edge to the bricks.

3. What did you expect to happen instead?

I expected way darker edges for Vulcanus, brown ground isn't really a thing there.

4. Does it happen always, once, or sometimes?

As long as they are placed alongside the edge of the map.

Thanks for the report.
Currently, the tile transitions are defined once per pair of tiles, so transition stone path -> out-of-map is always the same.

The surface has information about what tile is "underneath" the stone path tile, so the path can be mined. It would be possible to change the tile transition system to work differently, and take the original tile into an account somehow, but it doesn't feel like a big issue worth solving to me at the moment. I think we kind of gave up on out-of-map transitions in Space Age, and many new tiles use just generic mask and don't even have an edge.

Thank you for the quick reply.
I appreciate the insight into how tile transitions work and understand that addressing this issue would require reworking the tile transition system significantly.
I can see how focusing on other aspects of the DLC might take priority, especially since transitions to "out-of-map" aren't critical for gameplay.

Looking forward to a potential fix in the future though, Space Age is very awesome so far, can't wait to land on Gleba
