I'm in the process of learning how to use the Dark Radiant editor. I'm creating a "test mission" for myself, I already built my map with all the models, entities, the objectives I set are working perfectly, there is only one thing I can't tackle: Readables. I don't know why, but when I put down a readable prefab on my map, edit it in the Readable Editor, and try to save it, I get the following error: "You have imported an XData definition that is contained in a PK4, which can't be accessed for saving. - Please rename your XData definition, so that it is stored under a different filename."
And when I rename my XData name, I get the following error: "Mod path not defined. Using base path."
Everything so far is crystal clear with Dark Radiant, but I seriously can't understand this whole thing about xd files, XDatas, and stuff. Can anyone help me with this?
