Scenome meshes use generic attribute channels to define sets of parameters. Channels include position, normal, color, texture, and number. You can add a generic channel to a mesh and specify the type of channel. Technically, Scenome allows you to have an unlimited number of channels, but there are practical limits.
Each material you wish to apply to a mesh requires another texture channel. If you wish to apply multiple shaders to a mesh then you must use a mesh with multiple texture channels because shaders are linked to materials. In order to apply multiple materials to a mesh, you must have multiple texture channels.
A position channel contains vertex position attributes. These are stored as double-precision floating point values that represent the vertex world space position along X, Y, and Z.
A normal channel contains...
A color channel contains vertex color attributes. These are stored as integer quadruples that represent the color value from 0-255 for Red, Green, and Blue, with the remaining 8-bits reserved for alpha.
A texture channel contains vertex texture coordinate attributes. These are stored as double-precision floating point coordinates that represent the world space texture coordinate value along U and V.
A number channel contains...
