Help adding a new agent

[uanime5]

I'm current having problems adding a new agent to Shogun 2. I've added a new agent (korean_inspector) to the agents DB table, created a recruitment effect (agent_availability_quality_korea_inspector) in the effects, assigned this effect to this agent in the effect_bonus_value_agent_junction, and assigned this new effect to several buildings in the building_effects_junction. However when I go to the recruitment tab there's no icon that will let me recruit this unit (for example if you wanted to recruit a metsuke you'd click on the image of a metsuke). Do I need to create a new image for this agent and if so where are these images stored?

This problem isn't due to this agent not belonging to the same religion as my faction because it doesn't have an assigned religion.

If the unit would be recruitable, there would be atleast a black icon.

Have you also assigned a new unit_variant model?

Which DB table is the unit_variant model in?

Also I'm talking about agents (such as the metsuke or ninja) rather than units that can fight on the battlemap.

Agent_uniforms or something like that.
Edit: Then assign it to the agent in agent_culture_variants.
