Generate new output attribute with the parameter size in Pattern POP

Not sure if bug or RFE,

When I use a pattern POP and store it to a new attribute in the output attribute scope parameter, it doesn’t create an attribute with the same dimension as specified in the parameter size higher in the window.

When using P or creating N, it leaves the intended size (makes sense are they are expected attributes) but when I create a custom one, suddenly the two last columns grey out, while the size parameter still stays at 3.

Would it be possible for the created attribute to be set as the specified size? Or also grey out the size parameter if this is not an intended use to resolve the inconsistency.

I understand that the “correct workflow” would be to create the attribute first, but this workflow here works with size 1 parameters so why not :slight_smile:

Don’t hesitate to point if I missed something and have a great day!

Hello @Neurotypique,

To set the number of components of the new attribute, you can enable
Override Automatic Attribute
There’s an expression that links the number of components to the parameter size by default.

You can have a parameter size of 1 and an output attribute with 3 components - all components get the same value in that case. might not be so useful for pattern POP but we wanted to keep things consistent with other POPs.

Best,
