At my school we often use sketchup for engineering classes. so i made some models of buildings in sketchup and textured them and exported to xsi (i followed the guide about the matching the names of the textures in the .dae fail to match the actual textures and everything else) but i encountered problems with how textures were placed. it seemed very random where the problems were like some textured parts in sketchup would be black or textures in the interior of a building were on the exterior and stuff like that

btw i am using sketchup 8 and exporting .dae files to xsi 7.5 modtool

is a normal thing when converting from sketchup to xsi?
