Experimental:Attribute POP

Summary

The Attribute POP lets you:

Create new attributes
Rename attributes
Duplicate attributes
Delete attributes
Create matrix attributes

When you create a new attribute, you specify:

the name (choose from built-in pre-defined names, or create your own)
the type (float, double, int, uint)
the number of components in the attribute (1, 2, 3 or 4 only). Examples:
- A float type with 3 components is therefore a float3.
- A double with 2 components is a double2.
- An int with 4 components is an ivec4.
- A uint with 3 components is a uint3.
arrays of the above, for example create a array of 8 float3, appearing as float3[8]. The array length can be anything.
the default value for each component of the attribute

New attributes can also be matrices (done on the Matrix page), like creating a mat4x4.

Extra Information for the Attribute POP can be accessed via an Info CHOP.

Common POP Info Channels

Common Operator Info Channels

total_cooks - Number of times the operator has cooked since the process started.

cook_time - Duration of the last cook in milliseconds.

cook_frame - Frame number when this operator was last cooked relative to the component timeline.

cook_abs_frame - Frame number when this operator was last cooked relative to the absolute time.

cook_start_time - Time in milliseconds at which the operator started cooking in the frame it was cooked.

cook_end_time - Time in milliseconds at which the operator finished cooking in the frame it was cooked.

cooked_this_frame - 1 if operator was cooked this frame.

warnings - Number of warnings in this operator if any.

errors - Number of errors in this operator if any.
