The commonly used tools are Ohaba and Spica. Ohana can be used to modify texture and simple model blocks. The tools for modifying models are generally Maya and blender (PS for modifying texture). Ohana modified model does not support adding vertices of the model (that is, the number of vertices cannot exceed the original number), but the function of the model can be completely retained. Spica can support adding model vertices, but if the model is not handled properly, there will be various problems in the game. At the same time, the model edited by spica will lose some functions in the game (light and shadow layer and transparency layer of Pokemon model, and blink animation of NPC and Pokemon).
