Structure

Field(s)	Description
struct kdop_item	See k-DOP item. Flags: Bit 0: Water reflection Bit 1: Ignore cut planes Bit 2: No collision Bit 3: Invert geometry Bit 4: Stepped geometry Bit 5: Perlin noise Bit 6: No shadows Bit 7: No mirror reflection Bits 16-19: Color variant, 1-indexed. 0 means the curve doesn't have any Bit 20: Low poly vegetation Bit 21: Use linear path Bit 22: Detail vegetation
token model	Unit name of the curve model, as defined in /def/world/curve_model.sii. Here's the official documentation for curve units.
array_u64 node_uids	Contains four elements: the UIDs of the backward node and the forward node, followed by helper nodes (if used; set to 0 otherwise). Some variants of some curves define model locators for which the editor adds nodes to the map, which other polyline items can be attached to.
float length	Cached length of the segment. The maximum length of a curve segment is 1000 m.
u32 random_seed	Seed for vegetation etc.
float stretch_coef	Coefficient for stretching the scheme along the path. For some curves, this stretches the model; for others, it places its elements further apart.
float scale	Scale of the model. Does not affect vegetation models.
float fixed_step	If not 0, forces the model to repeat every n meters, overriding the default.
token terrain_material	Unit name of the terrain material for models like terrain_decal_*m.
u32 terrain_color	Color tint of the terrain as RGBA. Default is #FFFFFFFF (white).
float terrain_rot	UV rotation of the terrain texture.
token first_part token last_part token center_part_variation	Unit names of the first part, last part and center part.
token model_look	Look of the curve model, if applicable.
u32 height_offset_count array_float height_offsets	Defines offsets for individual elements of the building. Offsets are applied to elements in order. For instance, if you want the third element to have an offset of 5, the content of the array should be [0, 0, 5]. The editor uses this for the "Snap to ground" tool.
