| Tutorial 2. Applying multiple images: Eg. Car Decals. |
The basics:
On the left is a material with just a colour in the 'Diffuse' colour slot.
Add a 'Bitmap' Map to the 'Diffuse' Map slot and the image is rendered as on the
right.
Note the 'Diffuse' colour cannot be seen beneath the image, the 'Whole' image,
background inclusive, is used as the map. It should be obvious that this is not
what we want, we need to remove (or hide) the parts of the image we don't need.
We do this by using a different map.........the 'Mask' Map................
