related to Maya Array Attribute, having compound child.

[Hyun Seung Kim]

In fact, I have a question to ask.

Question: related to dynamic size on array attribute

Currently, I use array attribute containing compound attributes within

( target Matrices ( array ) - target 1st ( compound child  as matrix type) and target weight 1st ( compound child as float type ) )

When the plugin loaded and try to access the attribute but the size of array has not been increased.

Since maya array attribute is sparse, I thought, it should be expanded with elementByPhysicalIndex.

But Array does not seem to be increased.

Anyone might have an idea there is a way Maya API to handle array compound attributes?

Thanks in advance on any feedbacks!!

Hello Hyun,

I may be misunderstanding the question, but I'll give it a try if you don't mind ;)

As far as I know, when you have attributes and they have the default value,

maya doesn't save them anywhere, and when you ask for them, the default value is returned
( and sometimes only the values that are different from the default are returned, and you have to fill the array yourself )
Could this be what's happening?

Cheers!
Eduardo

Hello, Eduardo, sorry for not clear on question. Basically, what I am having as an issue is 

when plugin attributes created initially, array attributes can be expanded by arrayBuilder

especially on output Attribute. In my case, I want to set the size of input array attribute on plugin

dynamically but somehow, the method seems to be only working for dealing with output attribute.

later, I find it out as alternative methods that I used mel command ( getAttr ) to access on input array attribute

on maya plugin command, which seems to be the only way I can increase the array attribute size dynamically.

If you are interested in, I will follow up with actual source code and it might be much easier to read what I am trying to do..^^

thanks for response..!!
