Demo Limitations

I recently downloaded the free demo version and have gone through the tutorials but when I try to add an object and resize it, nothing happens…whereas in the tutorial, the object is scaled…(e.g. lengthening a box to create a car body)…

Also, does Unity only work with objects created in Autodesk or can a basic .jpg be used on top of a box, cylinder, etc.?

Unity accept a lot of files, 3D like from Autodesk, lots of 2D type like jpg, sounds, materials, shaders etc.

The free version allow you to resize your objects and affects materials (and a lot more). Are you sure you created an instance of the object in the scene then changed it’s Transform component or used the scale tool ? If you select the object in the project pannel the change the scales value, you won’t see anything.
