what is the best way to place a picture onto a surface? Let me explain my problem.

I want to put a picture of a hippocampus (slice of brain) onto a model of a hippocampus that I build. I first made the hippocampus shape out of NURBs (see picture below).

I wanted to put thisl picture just on the top surface of the model.

1) how do I prevent it from wrapping all the way around the whole surface?

2) how do I map a "non -square" image onto a surface. Image is oval without any background in Photoshop, but white backgorund shows up when i import it (like the photo below)

Thanx for any help......here's a picture of what I am trying to make..minus the white outer section

I guess you have to warp yourself around UVmapping soon. it´s not that hard to understand.

to answer your questions. when assigning a shader to an object your file is being wrapped all around the object. you could try to map the file onto some faces only. secondly if you don´t want to have the white background showing up try to map the alpha channel with your "background-image"

everything starts and ends in the right place at the right time.

yup

Yes, I started a UV mapping tutorial last night and it is working. Thank-you. I wasn't aware of this option until now. It looked difficult but is proving not so bad, and very useful.

I will try the alpha channel thing next.

Thank-you
