Hi,
I try to create a custom attribute in the hands of a character, in order to get a paste opposite function for the arms and legs, etc…
So my process is to create a function that add a custom attribute to acontroller, with max object tabs.
Let say that I have 1 object tab for the hand where the CA is added and other tab for the other hand.
after adding the CA, i put the arrays of left hand objetcs in his max tab, and the right hand in is max tab.
but, when I evaluate it, it appears that the other side objects aren’t in their list… and I dont understand why…
here I put a part of the script as it’s a huge code from my autorig:
------------------------- My lists of Arrays -----------------------------------------
L_ikNodesLS=#(),
L_fkNodesLS=#(),
L_Roots=#(),
R_ikNodesLS=#(),
R_fkNodesLS=#(),
R_Roots=#(),
L_Hands=#(),
R_Hands=#(),
clIKWirst = the control where the CA is added
---------------------------------------------------------------------------------------------

Somebody can explain me what I am missing?
Thanks you.
first of all (AGAIN) i want your to add unique attribute id to your custom attribute…
because i don’t want to meet one day any scene with your current setup
Why?
every time you define(in your case also create) a new custom attribute without attribute id, the system gives a random id to the attribute definition.
if you want to make any changes to your attribute source in the future you have to have them with the same id. otherwise ALL once created attributes are unique!
The only thing that makes them similar is the name.
i’ve seen a scene with 5,000 identical CAs. applied to one max node. Of course the developer of this attribute was much “advanced”, hi “knew” not just how to create CA but also how to duplicate it.
after you add the unique ID to the attribute definition every new created or currently loaded CA will be automatically updated every time you change the attribute
Ok so if I understand I should add an attribute ID, with different number for each hand?
Looking like this?:
IKFK_CA = attributes ik_switch attribID: #(0x7f7438e8, 0x4515b94a) for on hand and
IKFK_CA = attributes ik_switch attribID: #(0x7f7438e9, 0x4515b94b) for the other?
the numbers are random, i mean can I put the numbers i want?
Thanks.
i think that both left and right attribute are the same… it can be different by left/right flag. so they have to have the same id. and of course you can give an id you want. for example i use the same first part of id for all my attributes and plugins, and only randomly change the second part.
Ok, so you think had to rename the attribute in something like that:??
IKFK_CA_R = attributes ik_switchR attribID: #(0x7f7438e8, 0x4515b94a)
IKFK_CA_L = attributes ik_switchL attribID: #(0x7f7438e9, 0x4515b94b)
the point is that for creating my arms, I use the same fonction I made but I change the object I put in the arrays, in order to match the good right and left, so I use the fonction twice, and the strange thing is that the first arm created works perfectly, it’ always the last one which have the “Oside” lists empty.
ok… before we will fix the bug (if it exists), there is another question…
why do you use an empty modifier as an owner of the attribute? probably the only reason is that you saw this technique sometime somewhere…
what’s wrong with it? the only one… it can be collapsed and lost.
i would add the attribute to the baseobject of node. the only way to wipe it is to replace the instance … which is not trivial for an average user
ok sherlock !
you are right, i saw it and I repeat it… ah ah !
But for my defense, I don’t want to have all my custom attribute in the baseobject as it will mix with the other object rollouts, and it will be a little bit messy for the animators ( I am animator and I prefer get all attributes their own modifier)
I don’t think it’s a bug, I think i am the bug, sure i made something that make it not working…
Are you there Denis?
