I noticed that both Solo Sikoa manager attires, "Tribal Chief" and "Bloodline Suit", include the Ula Fala. This makes both of them look outdated and not suitable for modern matches.
So I decided to remove the Ula Fala from the "Bloodline Suit" attire. The other one has a more fitting name to keep the Ula Fala, plus the red Bloodline Suit is the worst choice to showcase the red Ula Fala — while the black Tribal Chief attire creates a better contrast.
With this small mod, you'll now be able to choose a Sikoa manager attire either with or without the Ula Fala.
As a bonus, I included two new renders I made, that replace the original ones, which are not photo-based. The Tribal Chief render includes the Ula Fala, so both renders clearly highlight the difference between the two attires.

Installation:

This mod is designed to overwrite the original attire with the Ula Fala, so it strictly includes only the files necessary for the Ula Fala removal. It is not intended to add a third manager attire — to do that, you would need additional files from the original game and Discovery/Tribute tools.
So if you're fine with overwriting the original one, all you need to do is place the files in your \characters folder and bake. Same logic applies to the renders: both use the original filenames, so you can drop them in \UI\Assets\Roster\TypeA and bake — they’ll overwrite the originals.
