UVWs

Texture mapping controls adjust how textures are positioned, scaled and oriented across a 3D surface. These settings modify texture placement by manipulating the underlying UV coordinate system, allowing precise control over texture alignment and repetition without altering the original texture or model’s UV mapping.

Parameters

Display Name	Name	Type	Default
Texture Coordinates	texture_coordinate_uvw	dropdown(int)	texture_coordinate_uvw
UV Set	uvw_uv_set	int	0
Ignore Missing Images	uvw_ignore_missing_texture	bool	false
Missing Image Color	uvw_missing_texture_color	color	0.0, 0.0, 0.0
Use UV Coords	uvw_use_uv_coords	bool	false
UV Coords	uvw_uv_coords	float2	0.0, 0.0
Offset U	uvw_s_offset	float	0.0
Offset V	uvw_t_offset	float	0.0
Wrap U	uvw_s_wrap	enum	warp_periodic
Wrap V	uvw_t_wrap	enum	warp_periodic
Scale U	uvw_s_scale	float	1.0
Scale V	uvw_t_scale	float	1.0
Flip U	uvw_s_flip	bool	false
Flip V	uvw_t_flip	bool	false
Swap UV U	uvw_swap_st	bool	false

Scale	uvw_projection_scale	float3	1.0, 1.0, 1.0

Texture Coordinates

Chooses between pre-defined coordinates on the asset, object space, or world space systems.

UV Set

Allows selection of alternate UV coordinate spaces to be used for mapping the material. This will only produce an effect if multiple UV sets are pre-defined on the model.

Ignore Missing Images

Will not error out if the texture is missing. Instead, the missing texture will be replaced with the color specified in the Missing Image Color parameter.

Missing Image Color*

The color to be used in the advent of a missing texture.

Use UV Coord

Toggles the use of an alternate UV coordinate system that you must define.

UV Coords

This will typically be read from a texture or primvar.

Offset U

Adjusts the horizontal position of the texture on the surface by shifting it along the U axis. This can be used to fine-tune the alignment of the texture without altering its scale or rotation.

Offset V

Adjusts the vertical position of the texture on the surface by shifting it along the V axis. This can be used to fine-tune the alignment of the texture without altering its scale or rotation.

Wrap U

Controls how the texture is wrapped along the U axis.

Wrap V

Controls how the texture is wrapped along the V axis.

Scale U

Adjusts the scale of the texture along the U axis.

Scale V

Adjusts the scale of the texture along the V axis.

Flip U

Flips the texture along the U axis.

Flip V

Flips the texture along the V axis.

Swap UV

Swaps the U and V axes of the texture.

Projection Mode

Controls the type of projection used to map the texture onto the surface, if a projection mode is selected as the Texture Coordinate Space. This uses standard projection systems that are commonly used in 3D applications.

Translate

Translates the projection system along a vector.

Rotate

Rotates the projection system around a vector.

Scale

Scales the projection system.

See Omni PBR UVs for examples.
