How do you achieve this effect?

Over the last couple of years UV layout in Maya has changed for the better. In this course we're going to be taking a look at some of those changes as we UV map an entire character

if you mean the reflection with all the white spots... then you can try HDRI

You might be.

In the main GIJoe pop-up control window, under HDRI Fake, there is a checkbox. That needs to be on in order for your color image to be evaluated/calculated/faked as a HDRI image to achive those cool highlights and reflections that you need user added image

Here is an image for you to see what I mean:

Arrow 1 when this box is checked, you can put your mouse over almost any piece of text in the GIJoe panel, and get help on what it is/does.
Arrow 2 You said you added a color image in this color slot, so I won't talk about that user added image

Arrow 3 when you add a color image to the color slot (see Arrow 2 ), in order for the HDRI effects to happen, this checkbox needs to be checked.

Hope this has helped a little user added image

I did have that checked, and it didnt seem to make any difference. What kind of image should i be using for the HDRI image?

Does anyone have a sample of how this should turn out so i can see?

Thanks for your help so far

Oh, btw, use HDRShop to convert your .hdr images to Floating Point tiffs for use with Maya. (GIJoe specificly)

I believe that targas work too, but I just stick with what Pixho said, and use FP Tiffs user added image
