Triangles

Many quads are in fact triangles: the last two vertices have the same PNTA and TXCA entries, and the ARGB color is (255, 205, 205, 205) (80% gray, 100% opaque). There is also a flag specifying that.

Flags

At runtime the following flag values are also used:

0x00 00 04 00 - set at runtime for quads hidden with *env_show*, never used in files

0x20 00 00 00 - set at runtime for Jell'Oed quads, never used in files

Stairs up/down

These 2 flags are used instead of the ghost flag when the pathfinding separator is placed at the bottom/top of the stairs.

Stairs

This is applied to the invisible ramp quad that covers the stairs. In general this flag is also applied to the visible stairs geometry but there are some exceptions (errors? see level 19 stairs).

No occlusion

This flag tells the octtree raycaster to ignore the quad when doing ray/quad intersections. This is tipically used for small quads that are unlikely to affect the overall environment visibility.

Projection plane flags

These 2 flags can be 00, 01, 10 and 11. That means the values 0,1,2 and 3 which have the following meanings:

• 0 - No projection plane specified. One can be computed if needed. Never used in files, may slow down the game if used.
• 1 - Project quad on XY plane.
• 2 - Project quad on XZ plane.
• 3 - Project quad on YZ plane.

The projection plane is used to determine if a point is in a quad (this point is usually the result of an intersection between a ray and the quad plane).
