Determines the type of
Material that is supported by a
MaterialAppearance instance. This is a trade-off between
flexibility (a wide array of materials) and memory/performance
(required vertex format and GLSL shader complexity.
Members
All materials, including those that work in tangent space, are supported.
This requires
position, normal, st,
tangent, and bitangent vertex attributes.
Only basic materials, which require just
position and
normal vertex attributes, are supported.
Materials with textures, which require
position,
normal, and st vertex attributes,
are supported. The vast majority of materials fall into this category.
