Args Files - Arnold for Katana

Katana populates the UI for editing shader parameters as best as it can by asking Arnold about the shaders or by having next to a shader library an Args directory with args files, but you may edit the display of the shaders by clicking the icons on the right-hand side of each shader parameter; you can then save the resulting presentation to a .args file and have Katana load it later.

KtoA comes with args files for all built-in shaders and all common shaders that ship with it.
