What's your suggestion?

I want to using custom model for Uchigata but when i try add CustomModelData to Uchigata item, Uchigata Sheath can't change the model or the texture.

If possible, i want to add that from future update because i have lot custom texture/model I want try using epicfight mod.

Sorry to disturb you after so long

In fact, there is a legacy texture package with the same function inside the modpack, which may inspire you.
I previously attempted to modify the model and texture of WOM's satsujin and satsujin sheath, but did not encounter similar issues. Perhaps Uchigatana Sheath and Uchigata have the same problem.
It is worth mentioning that it is best to use a JSON model for Sheath, and accurate positioning of the player's left arm position is required to ensure the final position is correct, which may require repeated adjustments.
