Hi,

I'm going through Sidefx tutorial Lesson6: Attributes and Variables. Link below.

https://archive.sidefx.com/index.php?option=com_content&task=view&id=2186&Itemid=361 [archive.sidefx.com]

In this tutorial, he created an attribute “ari” from the color value, delete color attributes by adding point op with none color, and add color again by adding point op and calling $ARI values. file attached.

When I call the “ari” values if I use “@ari.x, @ari.y, @ari.z” it works fine. But when I use “$ARI1, $ARI2, $ARI3” which was how he did in the tutorial, it fails. Why calling through “$” fails?

Thanks,

hb

i can not look at your file right now, but when you want to use variables down the chain you have to map an attribute to the variable. you can do so using the addvariablename VEX function in an attributewrangle or using a create attributeSOP that has a field for naming a variable, you have to set the value to the wanted attribute there.

using variables gets replaced by an @attribute workflow, so as far is i know most people avoid using the old $VAR system.

hope that helps.

thanks for your answer.

i guess i'll focus on getting to use @attribute workflow.
