| By selecting the arrow to the lower right
of the source editor, you can choose the mapping mode you desire for your material. |
 |
| Each mapping mode will "wrap"
your material differently around the object (s) you have selected. In many instances, you will have to experiment with the mapping mode to
perfect your material. Remember this when you see some material abnormality in your
image.
This material will be used in this portion of this tutorial. Reflection
was reduced in the default material. |

| Object Space: When using this
method of material mapping, the material will appear the same no matter what the object's
position in the Bryce environment.
Notice that all nine spheres have exactly the same
material applied to each one, i.e. they are all alike. |
 |
| World Space: When using this method
of material mapping, the material will differ depending on what its position is in the
Bryce environment. It is a common animation error to see the material change as the
object moves in the Bryce world, if you see this in your animations, be sure to
check if the material is set to World Space. If it is, set it to something like
Object Space.
Notice that all nine spheres do not have the same
material mapping. This is because of the different coordinates in the Bryce world. |
 |
| Parametric: In this mode, the
texture is applied as if it were a decal. If this method were used on a cube, one
iteration of the texture would be place on each face.
Notice that though the 9 spheres look alike, they differ
from the "object space" material mapping mode. |
 |
| Parametric Scaled: This mode works
like the world space mode. Textures mapped in this mode are not scaled with the
object.
Notice that though the 9 spheres look alike, they differ
from the "object space" material mapping mode. |
 |
| World Top: In this mode a 2d
projection of the material is applied from directly above it. If you move the object, or
rotate it the texture does not move with the object. See the animation error comment above.

 |
| Spherical: In this mode, a 2d
projection of the texture is mapped onto a virtual sphere that surrounds the object.
It is then applied onto the object.
This is an excellent mapping mode to reduce material map
"stretching" when applying a picture to a sphere. |
 |
| Cylindrical: In this mode, the
texture is mapped onto the front of the object. It is wrapped around the right and
left sides all the way to the back. Edge pixels going to the center appear on the
top and bottom of the object. |
 |
| Reflection Map: In this mode, a 2D
projection of the texture is applied to a virtual sphere that surrounds the scene.
The texture is then reflected off of the sphere onto the object.
This mode in effect reverses and inverts the texture. |
 |
| Random: This mode randomly applies
a 2D projection of the texture on the surface.
|
 |
| This is
one of my favorite material mapping modes for bump. It can remove a lot of bump
mapping errors in your image! Especially the long "gashes" that appear in some
of them. |
 Not Random Bump Mapping |

| Object Top: This mode applies a 2D
projection of the texture to the top of the object. The texture will rotate and
scale along with the object.
Notice that the material does not extend to the bottom of
the object. |
 |
| Object Front: This mode applies a
2D projection of the material to the front of the object. The texture will rotate
and scale along with the object.
Notice that the material does not extend to the back of
the object. |
 |
| Object Side: This mode
applies a 2D projection of the material to the side of the object. The texture will
rotate and scale along with the object. This mode is similar to object front, only
applied to a side. |
