I basically just want the visual part of this mod (not the actual entities), so I turned off the construction aspect and hid all the recipes. Now I basically find myself running "/paint-pipes" every few seconds when building something new that requires complex pipe routing, and I wish I didn't have to :) I have the planner as well, but that is also cumbersome to use. Wish all the coloring happened automatically when I placed the entity.

Upon placing a pipe, would it be too much overhead to just automatically call "/paint-pipes"? If it isn't, it would be fantastic if that were an option in this mod.

+1 for something like this. i don't even want the new recipes, but automatically painting all existing pipes would be awesome. is there some other mod that only does that?? and ideally the colors would be r/g/b customizable in the mod settings tabs.

I like this idea a lot, to make the process completely seamless. I'll look into possible implementations. The current command searches the entire surface and processes every pipe/pump/tank entity to see if it should be painted, which could have a noticeable performance impact if run every time a pipe is built (I'll test that though, perhaps it's not so bad).

Fantastic.
If performance will be an issue, maybe only search within a few chunks radius from the cursor??
