Maya Help

I'm a Maya n00b and am incredibly stuck on some simple texturing stuff. Basically I have a model of a guitar and need to put a picture of a guitar on the top side of it. I can't even manage that though...

If there's anyone that can spare me a few minutes on MSN to help me out, it'd be much appreciated! Reply or PM if you can save my ass :)

Man I suck. I'm still stuck :(

That tutorial really needs fullsize screenshots... the tiny thumbnails are useless

cant you just apply the texture then just play with the UVW mapping like you can in 3ds max?

Here's some simple steps:

select your polygon mesh and then do an auto-mapping from the UV menu. Not sure which version you're in so I'll keep it vague and you should hopefully find everything.

Once you've done an auto map, go into the UV window and have a look. I'm pretty sure that's just window>UV texture editor.

(ignore the following if basics not needed)

The way UV mapping works is that every polygon face on your model has a co-ordinate in a 2D "map". With the automapping you should now see every face (mostly separated/disconnected) layed out in the top-right square.

By default you should only be seeing lines, which is just edges mode. You can't move anything in edges mode, so if you hold right-click in the UV window and set it into UVs mode, you can pull the vertexes of the UV map around (does not affect your physical model). FYI there is no manipulation you can do to the UV map that will change your actual polygons in any way, it's simply the instructions for which pixels in an image get mapped to which face/s on the model, and which part of which face, etc.

A good thing to do now is to make a jpg (or whatever image format), which is covered in a dense number grid or some other dense set of unique markings, and apply it to your model. When you go into texture view (press 6), you'll see some of the numbers appearing all over your model.

In UV mode in the UV editor window, select bunches of UV points and shift them around the UV map - do this while still looking at your model, and you should see the image 'traveling' across the surface as you move points around. This is the map changing and assigning different pixels to different parts of the mesh.

So once you have idea of how it works, try some different mapping types (the auto map is handy for some things but actually quite a shit layout), because you'll need much better mapping to get to where you want to be.

Select all the side faces of the guitar and do a cylindrical map for example - you should see only those selected faces get updated in the UV window. Move them to their own space (in UV mode), which you can do easily by going 'select shell' from the UV menu rather than trying to marquee-select overlapping points.

This new mapping will probably have given you stretching (you'll see what I mean - it's when certain UV face sizes are relatively disproportionate, and too many or too few pixels in your image reside in that area of the mesh) so now you need to manually manipulate some of the UVs to make UV spacing closely match your polygon spacing in those areas. This can be annoying and time consuming.

Anyway...once you have a map that you think might work, which can take a while, from the UV editor export the map as an image (very lowest in the left menu). This gives you a tiff, iff, or whatever format you choose with your UV lines in it. You can then take that into Photoshop and use it as a map for placing specific parts of the image exactly onto specific parts of your model.

Hope that makes sense.

I PM'd you my msn as well so give me a buzz if you need a hand.

Good luck.
