Sure, here it is. I sadly can't upload the model directly since the site doesn't allow it so here's the google disk link https://drive.google.com/file/d/1ZelhVfUrJql_KqBJBESwUXvNzZ1tgTac/view?usp=sharing. The name of the textures may seem weird but they are correct, and they are both located in base/models/map_objects/mymapname directory along with the model, so I really have no clue why Radiant fails to load them
I just figured out that if I put the textures just to GameData/base folder, for some reason Radiant loads textures successfully. But sadly the model still remains untextured in Radiant, despite textures being loaded
