how to test if an attribute exist?

hi, how to test if ice attribute exist or not initialized?

Hi,

just if attribute exist, I think you can't (successfully) test this, at least in ICE tree. Once you have get data node that has defined context, your attribute actually exists.

But, if you know what value you can expect from your attribute, you can do some logic with output, for example, if it's not zero, then....

At least that's my understanding.....

You could do something like what the Get Texture Map Color compound does with First Valid.

hi,

just another one from 'first valid' creativity... this will return true if curve is plugged into the port, and false if doesn't
