Hi everyone, I am having some issues with expanding the portrait generator for the game. In other words, I want to create unique portraits for each general, but the game only uses a common image for them. I've tried modifying it, and it only changes the portrait outside the game, but once I enter the game, it reverts to the default image.

Here's what I did:

First, I created an art_set_id. For example, to create a unique portrait for Liu Dai, I added a row with the art_set_id as 3k_art_set_historical_liu_dai_general and kept other columns the same as Liu Bei.
Next, I went to campaign_character_arts_table and set the art_set_id as 3k_art_set_historical_liu_dai_general, age 16, uniform as Liu Bei, card as 3k_main_hero_special_water_liu_dai, and portrait as 3k_main_hero_special_water_liu_dai. Other columns were kept the same as Liu Bei.
Finally, I went to character_generation_templates_tables, found Liu Dai, and simply changed the art set override column to 3k_main_art_set_historical_liu_dai_general.
Despite these steps, the in-game portraits still revert to the default ones. I don't know if I'm missing any steps or doing something wrong. If you have any advice or know what I should do next, please let me know.

If there are any mistakes, please excuse me as I am not very proficient in English.

Thank you in advance!
