Hello dear friends. I tried to browse old threads and review online examples of mods, but I really struggle to make Modbuddy create my mod in a way I want it: - I made a replacement for Art Museum, Concert Hall. - All ingame parameters and icon work fine. However I seem to be unable to reference it properly to display the art of the BUILDING_MUSEUM_ART, so it currently is invisible. I have uploaded the mod to the workshop with a notice to those who dislike invisible buildings: http://steamcommunity.com/sharedfiles/filedetails/?id=1214326139 I would love to figure out how to do it properly. Here's what I tried: 1) Used default Mod.Art.xml which came with "New building" basic project. 2) Created Buildings.artdef in the default project folder. 3) In Project settings added FrontEnd Actions and In-Game Actions with type UpdateArt and file (Mod Art Dependency File). 4) Cut out everything from default Buildings.artdef besides the BUILDING_MUSEUM_ART entry, and renamed it to BUILDING_CONCERT_HALL. Besides following what seems to be a correct order, .dep file is not generated and my building is still invisible. I was sitting up to 6 AM trying to make it work and I am ready to give up... It is a bit weird that it is easier for me to make my own game in Unity 5 than to figure out this . But I don't want to give up, because I want to return to my Model making and create models for CIV6. If anyone can assist me, I would be glad!
