New wonder, existing 3d art

[Ieolus]

I apologize in advance if this has been asked and answered.

I would like to create a new wonder for my mod and use the existing 3d art assets available. I am able to use the existing icons so the new wonder shows correctly in the Civilopedia and such, but it is blank in game.

Can anyone guide me in how to do this?

Thanks!
