Looks to need a further update, Welcome sign not showing up on the list in customs prefab similar to what Dannage was saying.

Yo, I found your comment on a video on YouTube and it led me here. This helped me out a ton! I appreciate it. One small note though, from my experience trying it just now, you don't have to flip the picture horizontally. It just needs to be flipped vertically. Thanks for the help!

Updated May 2021
now works with the current version of ModTools

I'm not using Modtools at the moment, just wanted to add some text using PO only - but that seems to be doing a mirror image of whatever i write, unlike on other road signs (but they already have space taken with town names). Not sre how to go about it.

a little tedious, but works fine for me. Have created 2 (so far) 'gated communities' in my city and created 2 signs. Thanks!

Didn't work for me, failed when I got to the custom prefab bit, as welcome sign didn't appear in the list, even though it was loaded. This is the fourth sign template I've tried to use and failed, so it's obviously me, I must be some kind of stupid.

Jordan, did you enable ModTools, exit game and then launch game again? It won't work completely unless the program launches with it already activated (found through trial and error).

Also can't get ModTools to open.

Weird bug: Procedural Objects turns the object green.
