Is it possible for a bunch of instanced objects to have unique varible values when using the same custom attribute definition.

For example say I have two spheres '$sphere01' and '$sphere02' which are instances of each other, And a Custom Attribute definition which looks like..

CaTest = Attributes TestAttrib
(
Parameters main
(
CAn type:#integer
)

)

If i add Catest to sphere01 like this

custAttributes.add $sphere01 CaTest

Then i find that $sphere02 also has the custom attribute.

Worse still if I change the varible in sphere02 ..

$sphere02.CAn = 2

I find that

$sphere01.CAn == 2 is true as well

Is there a way round this so that the variable stays unique ?

custAttributes.MakeUnique $sphere02 CaTest does not seem to apply in this case.

I actually need to store a material definition in the Custom attribute so 'Node user properties' won't really help in this case.

Can any of you guys help

You can't have unique CA's on an instanced baseobject. Instead, make a reference of the object and apply an Attribute Holder onto both objects (you need to apply the modifier to each object separately, otherwise the modifier will be instanced as well and then it won't work for the same reason). Then, add the CA to these modifiers on both objects. This will maintain the instanced baseobject, but with unique custom attributes.

Hope this makes any sense! :hmm:

Thanks Martijn

Arrg .....

custAttributes.add $sphere CaTest BaseObject:false

seems to work

Man i've spent hours banging my head trying to sort this out, and i soon as i write the post i find the answer
