Experimental:Blend POP

Summary

The Blend POP lets you blend together an attribute that occurs in all of it input POPs, such as the P attribute of all the inputs.

There are at least 8 blend types. The simplest blend types will do operations like average an attribute of all the inputs, or take the maximum, minimum, sum or product of all the inputs for one attribute.

The more complex blend types will mix based on a Blend Input factor (often a number between 0 and 1) for each input.

You can specify more than one point attribute, more than one vertex and more than one primitive attribute to blend at the same time.

You can get blend weights from attributes of the input POPs.

The Blend POP's architecture for handling multiple inputs is similar to the Attribute Combine POP.

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.
