I am trying to make a ship mod (my first one) to give the Pioners some ships of their own, I wanted to give them a destroyer whith a not so military look and thought about kitbashing the L miner with some station part and the auxiliary ship "sail" to make a light destroyer, I followed brummbear's guide and managed to get the ship in-game and give it a collision that matches the new shape, but something went horribly wrong in the conversion, while the ship looks perfect on blender it has some parts that are way bigger and not in the right place in-game, moreover, the textures on the kitbashed parts are way uglier and the paintjobs, while look sharp on blender are blurred in-game

does anyone have any ideas on why this is going on?
(the kitbashed parts are MRE production parts + the sail/radiator of the auxiliary ship)
how it looks in blender: (i moved lod 0 to show the sharp paintjob channel)

how it looks in-game: (the sail structure is fine, but the sail itself is larger and not in place, not to talk about the other floating pieces of the MRE parts)
