Hey all, I have been using a plugin recently known as pipe placer, and it has been really useful. However, I have been noticing something weird where the pipes will change to their default silver color without being edited sometimes.
They could go from looking like this:
If you look at the top image, valve boxes are black, pipe parts are red, and the pipe rings are black.
In the second image, some of the parts have changed their color to grey.
The fact that the pipes are fine in the first image but different in the other makes me guess you have parts ontop on each other.
Typically when you have the same part but a different color duplicated perfectly inside of the first part, Roblox can’t decide which one to show. I’d check if there’s more than one part overlapping.
