Also, r[t]s, I think everyone here uses the custom toolbrush, haha. I know I do. It's alot quicker and easier. I do square by square, yes, but only initially. After the custom brush is done, I save it and load it whenever I wanna use it.
Here's the brush I currently have for Twilight. I warn though, it is not yet complete. I still have yet to add the left and right corners, as well as the inner left and right corners. I will also make smaller sides and corners (2x2 and 3x2), as well as metal plating, so you don't have to

about the platings on the bridge. It's a pain.
Speaking of which, I should finish that soon(maybe tonight). Maybe I'll add the "reservoir" brushes as well(they're small, very small, 4 brushes of 2x1).
I'll edit this post when I finish the Custom Brush(or make a new post(and remove the old brush), if people reply before I am finished)
To load the brush, put this in your StarFroge > Data folder, run StarForge, select terrain layer, you will see on the left hand side, under a box with different tiles, a button [ Custom ] click on that, then in the box, click load, select TwilightDock and voila, custom brush.
Enjoy. Oh, and it's for StarForge.
EDIT: Finished the Custom Brush for the entire dock and uploaded the new one. Also have 4 2x2 tiles of "docking floor" and a 2 4x2 tiles of "docking floor". With some fiddling around, you can pretty much make the lines and stuff fit(at least half decent).
Yes, I know the Inner left and inner right corners look like... well they could look better, but it's what I can come up with(at the moment). I will try to make a better inner left/right corners, but not right now. I am pressed for time and gotta go. Enjoy
