UV Coordinates—

Displays t he range of UV

mapping coordinates.

Normal—Displays the orientation of normal

vectors.

Non-Cl amped Color—Displays the "real" color

value delivered to the renderer in RGB order. The

renderer uses a floating-point range of 0.0 to 1.0 to

represent the range of each color channel. Thus,

1.0 is 100%, or 65535 (real color values can be

greater than 1, but are clamped by the renderer to

1).

Coverage—Displays the coverage of the surface

fragment from which other G-Buffer values

(Z Depth, Normal, and so on) are obtained.

Z-Coverage values range from 0 to 255.

Node R ender I D—Displays an objec t’s G-Buffer

Object channel.

Co lor—Displays the color returned by the m aterial

shader for the fragment.

Trans parency—Displays transparency returned by

the material shader for the fragment.

Velocity—Displays the velocit y vector of the

fragment relative to the screen.

Sub-Pixel Weight—Displays the sub-pixel weight of

a fragment. The channel contains the f ractions of

the total pixel color contributed by the fragment.

The sum of all the fragments gives the final pixel

color. The weight for a given f rag ment takes into

account the cov erage of the fragment and the

transparency of any fragments that are in front of

agivenfragment.

Sub-Pixel Mask —Displays the sub-pixel alpha

mask. This channel provides a mask of 16

bits (4x4) per pixel, used in antialiased a lpha

compositing.

You can also determine the type of file to render.

Depending on your choice of file t ype, you can

also set up options such as compression, and color

depth and quality.
