Week 9 Homework: 3 solidworks models in ut3

These are my 3 solidworks models exported from solidworks and 3ds max in ut3. The texture is my own image that I enhanced in photo shop.

Problems: I had some difficulty importing the model into max. The some of the faces would disappear and they tured black at different angles. I new it would be a 'normal' issue and I remembered Jeff telling me he had problems with his model when he first imported it into max, although I did not know exactly what to look for at the time. He suggested to tick of 'unify normals' when exporitng from max into ut3. Then this worked. Prior to this I began 'flipping' faces in 3ds max, and this also resolved the issue but Jeff''s way was much quicker!!
