Now I'm thinking the problem is in the object importing, since when I do a standard primitive it is not shown in a bounding box, but the wireframe.

If anyone wishes to see the file, e-mail me.

BTW, here is a render from it. I'm studying architecture. It is my 2nd exam for "Perspectives by computer". We're using Autocad (As I have done for about five years), si I took the model into vue "just to see what happens". I also removed some objects to make VUE perform faster.

guess which one was made in vue?

you're saying CG sunlight is actually based on a real thing????
