Game texture modding

[NoobDevM]

Soo hi, i am trying to change some textures of a game called "Snow Bros", after dumping i realized it was made on Unity and because of it the folders and files are different from the usual (Ex. Pokemon), i tried using SwitchToolBox,"AssetStudio" and "AssetBundleExtractor", the last two allowed me to see some resources of the game but i cant find the player model to modify it. So anyone knows what should i do? Where i can discuss/get some help about modding some textures? I dont know what to doooo >.<
