Please forgive me if this sounds like a really noob question, but ive spent the last couple hours reading about UV's and watching UV tuts on Youtube and im still a little lost on this one. and if anyone can help me fill in the fuzzy areas that would be great. I am currently working on a logo that I am going to render in Vray. However I was wondering what would be the best way to go about it. I would like to be able to control my shader/texture in a way I can deteremine where the hot metal shows through on the logo along with where the scratched metal parts show up. Would a UV layout be the best thing for this? Below is some screen shots of my mesh along with a current problem I am having. When I built the model I modeled the top half of the "S" then dulicated it and rotated it then merged the verts together to make the complete "S" however when I add a shader to it you can see a hard line where the the merge to place. Is there a way to fix this? Thanks for all your help in advance :) Top image is the problem I am having see the "red arrow" Second image is my mesh and third image is a mock up of what the final image should look like and give you a idea of the shader and texture I am going for in the end.
