attribute binding in Attribute Vop

[mirHadi]

hello

 

As a beginner , sometimes I'm totally lost in nodes and bindings.. etc.

 

- I don't understand the Attribute Bindings tab in Attribute Vop Sop.

don't we bind attribute inside the Attribute vop with Bind node?

 

- and, how can I add multiple attributes at once to the points?

(binding seems not to map the variables)

 

the way I did it, I used the Attribute wrangle node , like f@ foo 1, f@ foo 2... and so forth , is this right?

of course this also doesn't create a local variable to be used by other nodes!!

 

thank you in advance

well .. I used point(...) expression in copy sop to fetch the attribute from attribute wrangle and It is working... 

 

 

edit:  please help me out with my question if you could..

Attribute Bindings is to allow you to easily swap input attributes to work on, something like if you have wrangle like

f@result = f@value1 + f@value2;

you can define in bindings tab what attribute each one of them will bind to instead of literally binding to attributes value1, value2 and result.

 

as for creating a variable you can use  addvariablename() VEX function or Addattribute VOP. As well as Attribute Create SOP with Write Values Turned off

 

but for most of the cases you should not need to use variables

for Copy SOP for example just provide attribute names in Attribute Stamps parm

Thank you anim!

sorry for delay ..

I've got to do some more reading.. to see better what is going on!

 

in the case of attribute binding tab , 

If I open an old file, seeing through just vex code may be confusing to see what attribute is bind to what parameter.. , for example, value 1 refers to what , need to go to tab come back again tab back and forth!

 

Ps: now It makes sense.
