Custom Attributes


Recommended Posts

Hey All

There has been something that I haven't been able t figure out for quite some time. Whenever I create a custom attribute, and try to use it as a local variable, it doesn't work.

For example I created an attribute called zImpact and when I try t switch between two objects using the expression, if($ZIMPACT == 1, 1, 0) it doesn't work. I have to use the point() to call it in.

Example, if(point("../attribtransfer1", 0, "zImpact", 0) == 1, 1, 0)

My question is why can't I just use $ZIMPACT ?

The problem is that your Switch SOP is not processing things on a per point basis. $ZIMPACT is a reference to the current points attribute value for zImpact. The switch doesn't know about any currently iterating points. Your point() expression works because you are specifically saying look at point 0. If you tried using $ZIMPACT in a point sop it works fine since that op is actually iterating points.
