Structure

Field(s)	Description
struct kdop_item	See k-DOP item. Flags: Bits 0-1: Right -> terrain noise     0: 100%     1: 50%     2: 0% Bits 2-3: Right -> terrain transition     0: 16     1: 8     2: 4     3: 32 Bits 4-5: Step size     0: 4 m     1: 16 m     2: 12 m     3: 2 m Bit 6: Right -> Vegetation collision Bit 7: Water reflection Bit 8: Invert railing Bit 9: No collision Bit 10: No boundary Bit 11: Right -> No detail vegetation Bit 12: Stretch terrain Bit 13: Low poly vegetation Bit 14: Ignore cut planes Bit 16: No terrain shadows Bit 18: Smooth detail vegetation Bits 24-25: Left -> terrain noise Bits 26-27: Left -> terrain transition Bit 28: Left -> vegetation collision Bit 29: Left -> no detail vegetation
u64 node0_uid u64 node1_uid	UID of the backward and forward node of the item.
float3 node0_offset float3 node1_offset	Don't know what this does
float length	Cached length of the terrain segment. See Polyline item. The minimum length of a terrain is step size / 2. The maximum length of a terrain is 99999 m.
u32 rnd_seed	The seed used for placing vegetation.
token railing s16 railing_offset	Railing model and its offset, multiplied by 100. This is repeated three times, since there are three models.
The following parameters are repeated for the right and left side:
u16 right_terrain_size	Terrain size, multiplied by 10. The maximum size is 6500.
token right_profile float right_profile_coef	Terrain profile and coefficient.
token right_prev_profile float right_prev_profile_coef	Profile and coefficient for the previous terrain in the chain. Not sure why this is cached here, but terrains won't generate properly if it's just left blank.
array_struct vegetation	Three vegetation structs, see Vegetation struct.
u16 right_dvdm u16 right_dvd	No Detail Vegetation From and To settings, multiplied by 10.
End of repeated section
u32 veg_sphere_count array_struct veg_spheres	List of vegetation spheres. See Vegetation sphere struct.
struct quad_info	Terrain data. See Quad info struct. Repeated for right and left side.
token right_edge token right_edge_look token left_edge token left_edge_look	Edge models.
