SO... everything calm down.. now here is my ArtStation post about all the maps and art, which i created for this project.
Trash Diver art

All the assets where created in the Blender v4, wanted populate game with few different assets, so all the assets except main charated model was made low poly with one texture map. To avoid spending time on UV unwrap all the models UV's there made by Project From view (planar method), that gave me fast iteration times and reasonable UV map, due i used single color or color ramp for texturing that went better than i expected.

Main Character The Racoon was kinda similar low poly, majority UV's of model was same technique with planar mapping, except it had particle system on it for FUR. it was just simple particle system in Blender set as hair, did some combing and color from texture. Unfortunately did something wrong and Color data wasn't available in UE5.3.

 
Maybe later on will do post on Unreal Engine forums about whole project. Maybe :D
