Nodes > Main > Sample Mesh Data Texture

This node samples mesh attributes (Position, Normal, Velocity, Mesh UV) from a texture atlas generated by the Mesh Data Texture Custom Component, supporting effects like spawning particles from meshes and vertex animation. The source mesh must have valid UVs to work. See the Mesh Data Texture guide for more details.

Inputs

Name	Type	Description
UV Coords	float	UV coordinates in 0–1 range, used to sample the texture atlas tile.
Normal Offset	float	Moves the output position along the normal vector by this amount. Useful for spawning particles slightly on top of the surface.
Velocity Scale	float	Multiplier applied to velocity vector.

Outputs

Name	Type	Description
Position	float	Mesh position sampled from encoded texture atlas.
Normal	float	Mesh normals sampled from encoded texture atlas.
Velocity	float	Mesh velocity sampled from encoded texture atlas.
Not Valid	float	Returns 1.0 if pixel is outside safe bounds or having invalid pixel data, otherwise returns 0.0. Can be used to discard unwanted data or connect to a Kill Particle node to remove particles.
Mesh Surface UV	float	Mesh UVs sampled from encoded texture atlas.

Properties

Name	Type	Description
Normal	bool	Enables normal sampling from atlas if available.
Velocity	bool	Enables velocity sampling from atlas if available.
UV	bool	Enables UV sampling from atlas if available.
Interpolate Position	bool	Enables software bilinear interpolation for smoother position sampling.
