View Full Version : Expressions Carefull Help

What am I doing wrong with expressions?

I create an expression with BUILDER and then I apply the same expression to several elements.
I save the scene file and when I open again, it says there's an ERROR, a reference object absent.
The expression can't be applyed or removed anymore, and that POINT that means expression applyed is there.

I also got problems when I clone expressions.

What's the carefull to work with expressions in lightwave?

Need expression experts help here!

I tend to head for Relativity - it tends to be more robust and more intuitive. Did you give it a try? As a consequence of years of Relativity usage, I've never ended up comfortable with LW's own expressions. Caveats with LW's own system, that I've experienced through things like Vehicle Rigger and Maestro :

Objects or scene elements beginning with numbers tend to be misinterpreted
The _ character seems to cause trouble, as do long object names

Well, Im the opposite, never had a single problem using LW expressions, with the exception of user error ofc.

And its hard to say whats wrong without actually seeing what you've got and where the problem could lie... all I can tell you from your description, is that one of your item references is incorrect... which is pretty much what LW is already telling you.
