OK.
I just finished remodellind and reskinning the kart / drivers .
The result is a 1142 polys kart model, with skins reduced to 512 x 512. ( I had 1024 x 1024 before... )
I added more movement to the driver body, and corrected it´s arms and overall scale. The arms still look stretched, but its my view effect. I Like to drive this way in some games and reflects on my favorite drive position. But the scales, I´m sure they are ok.
I just took some in-game screenshots :
Well... Some little more adjusts to do, but..
Hope now its looking better.
