car transporter upfit (beaver tail transporter)

i have a question, if i were to make a car hauler upfit for the Gavril-H series, how would i place it into game as an upfit? welcome to any advice to blender also.

 

i would place it in the slot with the other upfits for the h-series. it just seems the most logical

 

this might make me sound very stupid but how would i do that? i’m very new to making a mod and i don’t know how i would do that?

 

i would start with automation or modeling on blender

 

i understand creating in blender, but i mean how would i put it actually into the game? as an upfit

 

info.json is what shows up in the game
