Adding
a decal to sphere:
|
|
In
my previous tip I stated you should use an image that is twice as
wide as it is high. This holds true for adding a decal to a sphere.
Below is the image I used to add a decal to a sphere. It is 300 x
150 pixels. |

The
blue area was masked in a paint program and converted to an Alpha
Channel. Then Spherical Texture mapped to the yellow sphere, it leaves
only the circle area visible on the sphere as seen below. |
