UV Maps And Other Attributes
The Redshift for Katana plugin will extract automatically the most common attributes available in the geometry, for example:
- Ppoint positions, including motion blur.
- Nnormals 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, rnmlrest 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
