Guide on adding a new model, animation, and creature to HoMMV

Hello! Could you please advise if anyone knows? I'm trying to get the Human castle model in HoMM 5 (the one that is displayed when building it, not on the global map). I copied the entire Geometries folder to convert the models and open them with AccuTrans3d. However, there are many files, and I don't understand if there is a way to separate what I need from what I don't, since their names consist of a set of letters and numbers. If anyone has encountered this, please give me some ideas on this issue. P.S.: The model doesn't necessarily have to be a single one; it can be separated by buildings. Perhaps that would even be better.

The city model is not a single one; it's a whole bunch of models - each building has its own model, and even in several variations - a model for the Griffin Tower, another model for the Griffin Bastion, and maybe even a model for the unbuilt version. In the data.pak file, in the \Arenas\Town\NewHaven folder, there are text files, for example: Angel_u0r0.xdb - model of the unbuilt Angel Tower (i.e., this is the model of the grove that grows on the hill) Angel_u2r0.xdb - model of the fully built Angel Tower This file contains links to other files. Angel_u2r0-Angel_M.(Material).xdb - this file contains a link to the building's texture, which is located right here, but not all textures for the Human city are in this folder, so sometimes you will have to search through material files. Angel_u2r0-geom.xdb - and this is what you need; this file contains the name of the geometry: 386F0CB2-A7EA-4C79-A12F-E85840FFC9F0 In short, look for geometry names in files with the -geom extension
