Instance Attributes

bake:activeudims

string

empty

Active udims for Integrator baking of texture atlases. Lists and ranges of udims can be provided in the string, for example: Attribute "bake" "string activeudims" "1001,1003,1005-1006". The default is "" which means all udims get baked.

bake:udimresolutions

string

empty

Udim texure resolutions for Integrator baking of texture atlases. Lists and ranges of udims can be provided in the string, for example: Attribute "bake" "string udimresolutions" "1001 512 512 1002,1003 64 32 1005-1006 16 16" If the string is empty (the default) then the Display Format resolution will be used.
