I mean to create buildings or game environment… I am noticing some errors about Objects not set in an instance of an object… Thanks
not sure what you mean. UNITY is not modeling software you can create basic model like cube, sphere etc and they OK to use. more complex model should be imported from other software like blender, 3d max or download from the web.
about the errors you see, it probably because your script is looking for object that not exist. check in the inspector for “missing object” and try to drag there some model…
