A basic tutorial that will probably be enough for most modders. Read this if you want to use Blender to modify existing assets inside a model (e.g. change or delete part of a mesh, change a texture, etc.)
How to change the shader parameters (including texture UV sampling) or swap shaders out entirely. Also there is a brief discussion about making the specular maps, and the issue of submesh order and transparency.
Here I give Dana a Thors Branch Campus uniform, from Trails of Cold Steel III. This is a longer tutorial, and it covers a lot of ground. Importantly for anyone looking to transfer models of any kind from another game, I discuss the quirks of Ys VIII including vertex colors. I also cover how to make a custom DLC.
Some games older than Ys VIII are supported by this toolset (e.g. Ys Memories of Celceta), but such games only accept meshes that are influenced by 4 vertex groups or less. This tutorial teaches how to segment a mesh into smaller chunks that adhere to this restriction. For modding these older games, also be sure to review how to create compatible textures using Cradle.
