Pyramid.Flags

The pyramid generates tiles that have semi-transparent pixels, which cannot be encoded using a 1-bit alpha channel.

The pyramid generates tiles that need to be processed with opaque texturing mode.

In opaque mode, missing areas (empty and void) are covered with the texture of the parent mesh sector quadrant. In non-opaque mode, missing areas are not rendered.

Opaque mode is usually used for surface imagery that has varying levels of detail, where the best available level of detail needs to be used for rendering.

Non-opaque mode can be used for rasterized vector shapes, where only the most detailed level is rendered.
