On the other layer we have made, we can fill in our texture.

It can be applied the same way as our test texture. Now hide the template layer and make a jpg with just the texture visible.

Now we make a transparency map to make parts of the suit transparent. Black parts don't show, white allows texture to show.

Apply the new texture to the transparency slot and set the value to 1.00

Remember to select all and apply to all.

Here is our finished product.
