Buffer max Height After you render a normal bump projection, this value
is set to the maximum distance that a projection ray travelled. Default=0.0.
If you want to use the Height Map texture element, you can render a normal
bump map to obtain the Buffer values, and then set Min Height and Max
Height accordingly, in order to get the best-looking possible Height Map.
Rendering Previews
A preview is an
AVI file on page 7118 that can help you preview the animation
in your scene. The preview uses lighting but not materials, so it renders much
more quickly than a fully rendered animation.
The preview commands are on the
Animation menu on page 7275 .
Make Preview on page 6220
View Preview on page 6224
Rename Preview on page 6224
Make Preview
Animation menu > Make Preview
Make Preview displays the Make Preview dialog, enabling you to create an
AVI on page 7118 file or custom file type preview of the animation in the current
viewport. You can also render a preview to a specified device.
When the preview is complete, the software starts the Media Player with the
preview _scene.avi file ready to play. (If you don't want the Media Player to
start, choose Customize > Preferences > General and, in the UI Display group,
turn off
Autoplay Preview File on page 7536 .)
NOTE Do not open any other program windows that cover up the viewport while
rendering a preview. Anything that covers the viewport will be rendered into the
preview AVI file.
