Hello everyone.
Im quite new to the world of arcgis and especially the part that this question is realated to, and that being the 3d analyst/arcscene part. Im trying to build a simple 3D of a city, and i've been following instructions from a very nice youtube video, ive downloaded the 3d textures from esri and everything was working fine in arcmap, until i put the layers into ArcScene.

And this is basically what happens with my buildings. The roads seem to be fine(even thought they dont look the same as in the tutorial, but at least they are not acting crazy).
Could anyone tell me what the problem could be and possibly how to solve it? I'd imagine its something to do with setting the heights of the building, but thats as far as i got.
Thank you in advance.
