## UV Maps And Other Attributes

The Redshift for Katana plugin will extract automatically the most common attributes available in the geometry, for example:

- **P**point positions, including motion blur.
- **N**normals at point or vertex level, including also motion blur.
- **st, st2, st3, st4 …**point or vertex level UV maps coordinates.
- **width** point level attributes to control the hair or points width
- **curves_width**
- **constantwidth**
- **rest, rnml**rest position and rest normal attributes
- **tangentu, tangenv** point level tangent values
- **creaseweight** creases weight attribute at vertex level
- **rotation, scale** strands point level rotation and scale attributes

## Arbitrary User Attributes

The plugin will extract all the arbitrary attributes available inside any location object, but only the attributes referenced by the object shaders will be used and loaded in the GPUs to save space and extraction time. Redshift supports float (from one to four components) and integer arbitrary attributes. Any scope is supported (point, vertex, face or primitive).

Redshift also supports user attributes at object level, that can be used with meshes, instances and point clouds. In this case Redshift can work with float attributes from one to four components and with single integers.

All these attributes can be retrieved at render time using several shading nodes:

- **VertexAttributeLookup** and **ParticleAttributeLookup**
- **RSUserDataColor, RSUserDataInteger. RSUserDataScalar** or **RSUserDataVector**
