Sketchup is a nice 3d modelling tool for the purposes of google but when I want to import it into another 3d modelling software, or make it suitable for a computer game it can be really annoying.
Here you can see what I mean. I just wanted to take a look at Mslb_Eemshoorn's Bugattà and you can see what I got as result in the attachment. The ship looked so nice in SU but you can't work properly with this type of model.
And since sketchup produces a lot of unnecasery polys the model got a poly count of 900 (you have to know that I already had removed some poly heavy parts before).
@Mslb_Eemshoorn you should redo that model it looks really great and please don't understand this wrong. You are not a bad modeller, but I think I would take less time to redo some parts of it from new than spend hours on modyfying all the small things. I would also suggest to remove the rounded parts which will be under the water surface in the game, since you won't see them at all.
Please don't get too much dissapointed by this as I already said your model is great an we need anything we get but I have to ensure that the models can be used in game.
Kind Regards
Joey
