View Full Version : Normal map and overlapping CV's

I have read a lot of the tutorials about normal mapping. I still have a hard time figuring out which type of normal mapping allows overlapping *edit* UV's.

So, if I have a crate, can I use one map for all sides of the crate? If I have a car, can I use one fender for all fenders of the car? What is that type of normal mapping called?

Thanks!! KS

cv's ?? you mean UV's.

I don't know what you mean exactly, for the cube you can use standard projection mapping like cubic if you want one map to fit the entire object. The car though is a bit advanced so uv mapping is the way to go there.

A UV map is basicly a set of coordinates in UV space, where U stands for horizantal en V for Verticel. Using that technique you can precisely place a map on the object.

I recommend looking for some good tutorials on the subject. :)

Ack, I meant UV's.

I've worked in situations where the studio said you cannot overlap any uv's.. I've worked where it was possible to overlap uv's. I am just not gripping the difference. Hopefully I can find a better tutorial.
