Exclamation BUMP MAPS!!!!!! HELP!!!!!!!!!!!

I know that in bump mapping, you take a greyscale .psd file where dark= less deviation from original form and light= more deviation from original form. I have no trouble with making a bump map, but my real problem is appying it. Now, please excuse me here, but out of sheer frustration I've gotta ask: HOW THE F*** DO I ATTACH IT? I'm sure this is a very newbie question, coz I'v been searching for ever and I can't find a tutorial that explains this in detail- I can't evn find one that explains it at all. So either google hate me, or this is a really nooby topic. Please explain how I do this!:shakehead

o and btw, I also need to know how to access/edit the skin map type thing ( i don't know what to call it) it is like the whole face valu of your model torn into peices and put up for display on a 2d plane. You can use it to apply paint effects and stuff....

The answer to the first question:

Open the Hypershader (Window>Rendering Editors>Hypershade), then create a new color (phong, blinn, lambert, whatever), then in the material attributes editor click on the checker box next to color. Choose File and then browse for your file. Then here is a small trick: Open the shader, click on the new color and choose graph network. Then delete the connection from the file to the color. Then click on the color, middle mouse button click the file and drag then let go over the final color. A menu will pop up asking how you want to connect it, choose connect to bump map. And toodaaa, there you have it, your file on a map.

I have a tutorial written to explain all that, im trying to get it posted but its so big i cant post it.

As for your second question: That is the UV texture editor (Window> UV texture editor). This is probably one of the hardest parts of Maya to me, so I cant explain it really well. But you need to unwrap your model and then you can export out an image from the UV texture editor, paint it, and return it back to the model.

Thanks so much, I've been searching for that forever... shoul'dve thought of the forums.... however, I'm not sure what you mean here:

Open the shader, click on the new color and choose graph network. Then delete the connection from the file to the color.
I'm sorry, I know virtually nothing of maya, and so you'll have to clarify: is the shader the material I've created, or what?
