Convert to file texture on complicated models

[derrhama]

Hi all:

Had a quick question re: my attempts to convert a file texture on a leg.

I have my shading network set up to project a tga on an animal leg. I want Maya to "bake" it in place, so that it stays.

I have used the Convert to File Texture choice in the Hypershade - however, when I try to save it, it produces a file, but the network and projection don't take. In fact, the UVs and coloring are all wrong.

I have been successful on simple objects (like primitive spheres and cones) with polygons, subDs, and nurbs - as the textures 'bake' well there.

So, in other words, is there a way to make projections come out well on a more complex shape?

Thanks for your time.

Are you using a poly/NURBS or Sub-D surface? Anything but NURBS, I'd highly suggest mapping the UVs and doing it that way - that's usually the best way for highly complex models. The Fundamentals of Maya: UV Layout training kit really helps with laying 'em out.

Hi,

I was using subDs at first, but then coverted to polys and Nurbs with more or less the same result.

You are correct; it might be time to do the UV Texture Training Kit. I thought that there might be an easier way of accomplishing this feat - the UV unraveling appears to be quite complicated.

On another note, I projected a flat surface through a planar projection. The UV created was correct; however, when I opened it in Photoshop, the projection was along the bottom edge. So, when I put textures on it and put in back into Maya on to the surface, it wasn't there. I went back into Photoshop, it appears that the texture needs to be in the MIDDLE of the screen for it to register --- is this correct?

Thanks,

You say that the projection was along the bottom edge, i'm not sure what you mean. Attach a copy of the UV layout here so we can take a look at what is hapening. Basicaly what you should get is a series of lines, which are the edges of the polygon object. Each edge of your object, which is 3D, is flattened into a 2D image, so that you can paint on it. Anything you paint within these lines will show up on the 3D model.
