unit_info - this line is disabled by the semi colon ( ; ) in front of the line. It's not used in M2TW and can be removed.
recruit_priority_offset_value - optional. It sets the priority for recruitment calculations, the lower the number the lower the chance that the AI will recruit it.

Thank you vey much. I can change portrait and unit-info pic for start officer like Cao Cao or reinforcement officer like Xu Huang now. But I can't find officer like Cao Pi in descr_stra or campaign_script. In descr_stra only write "record charactor J0135_CaoPi". There is no info about where his portrait stored or what kind of unit. Please help me.

[Seether]

That's because Cao Pi is only 9 years old at campaign start. If a character is underage and in a family tree, or isn't spawned via script, then they will not have certain entries (such as portrait) listed for them anywhere. Unfortunately, you'll have to manually search through the portraits yourself.

[Kiesennin]

Thank for your advice. But in export_descr_unit have code JiangJun_ZhongYuan_J0135_CaoPi. How can Cao Pi has exact uni when he appears. I have not had Cao Pi yet. But I have Xiahou Shang son of Xiahou Dun, his unit is ZhongYuan Cavalry. It must be ruled somewhere isn't it?

[Seether]

Because he was "of age" in the original RTW mod.
