@bspline Assuming we're talking about the new updated manuals, I added this question to the FAQ:
"Will Real Taxiways signs models/textures interfere with other addons?
There are several other addons that attempt to improve the appearance only of taxiways signs. Real Taxiways is not compatible with these addons, because it requires its own custom taxiway sign textures to create all the enhanced features listed in this manual."
For an expanded answer, Real Taxiways has always required those custom textures to work, since it adds many new types of taxiway signage. In the original 2020 versions, you had make sure these textures were installed separately, while it's done as part of the same package in 2024 (and now also 2020). As long as Real Taxiways has priority over these other packages, its signs will display correctly. However, you can still use any other airport enhancement addons with Real Taxiways, as they will still enhance other aspects of the scenery, just not the taxiway sign textures. I hope that makes sense. I'm happy to help you figure out any compatibility questions you might have.
