All models comes with 4 formats.
OBJ (NON-triangulated), OBJ*(triangulated), Lightwave and Modo.
These models are therefore compatible to used in most of the popular *packages on the market.
However, please do not assume the models will be "errors" free on your PC/Softwares, these models were created just polygons( no progremme or codes in
it!) there is unlikely models will cause problems, often the errors are cause by the softwares setting rather than model itself.
*Please download the free sample(s) to test on your PC/Softwares.
Level 0 - Suit for long distance shots away from camera, or usually the area which never close to camera.
Level 1 - Similar to Level 0 but with more polygons, although it is low polygon count but its primary shape of the model.
Level 2 - Good for most of the task, it has reasonable details as Level 3(High resolution) without the dense amount of polygons.
Level3 - High resolution and details, Round corners or all (most)edges are beveled, suitable for close up rendering purposes.
One common question is object smoothing ...
Smoothing is complicated and is not a standard thing or an error on the model(image 1). Most modeling applications use different techniques to make 3D
models appear smoother when rendered. This technique is also known by other names, i.e. Smooth Groups, Phong Shading, depending on the modeling
application. One way to "fix" the problem is adding(inserting) an extra face/polygon (image 2), but then this will increase the amount of the polygons.
Remember smoothing is only visual, it won't change the model at all. Carefully controlling the smoothing angle can avoid those unpleasing result without
increasing the polygon count (image 3), even my own experience is often vary on the particular models.
There are many information you can Google, one of the great and easy understanding video I found on the YouTube is created by Guerrilla CG Project, great
explanation of what 3D models - polygon, face normal and edge are, very informative and easy to understand.
