-----Texture Holes


Overview

This describes how to cut holes in your objects without changing their model.
I use this to make the Templar's helmet.
This technique assumes knowledge and understanding of the front-mapping technique so it is a good idea to read that before trying this.

Technique Instructions

I will assume you have an object to use this on. I had a helmet.

Make Image Maps

We will need a transparency map.

Apply Image Maps

I used a mirrorred map (see front-mapping).
Apply the transparency-image as Transparency and Specular Image-maps.
The application as a specular map is important to avoid a specular highlight on a bit of the helmet that 'isn't there'.
Scale the y-axes of both textures to 'cover' only the part of the object you want to cut a hole in.
Here are some before and after pictures:

Using Slice is another solution but the Texture-holes method is more adaptive and usually gives higher quality results.
