Searching for mods (looking for mods for Tribes of the East).

Are there any mods that improve the city portraits and the font quality in the city? (When its name is displayed)

I don't know of any. 2D textures are usually not upscaled. It's possible that this is due to interface bugs. Here's an example:

You create a creature icon that is 256 pixels, but when a neutral creature runs/joins, only a quarter of the icon is displayed in the window. Whether there are other such bugs is unknown; you have to play and look for them, and modders sometimes don't even play the game.

And in some things, you have to dig and study them. For example, in the puzzle map, each piece of the mosaic has coordinates to which this piece is attached. How to increase this - I don't know, and whether there are other such tricks - I don't know, and whether anyone wants to mess with this - no, it's not fun.
