daland4vfx Posted February 14, 2015 Share Posted February 14, 2015 Hi Everyone, I am following along with a CMIvfx tutorial. (Proceedural roads pt 1) Part of the lesson has you referencing another sop that has an expression. I keep getting an error. Probably something simple but any help would be appreciated. thank you david ref_error.hipnc Quote Link to comment Share on other sites More sharing options...
ayidi Posted February 15, 2015 Share Posted February 15, 2015 Sadly you ran into this problem: http://forums.odforce.net/topic/16159-what-is-the-reasoning-behind-the-variable-behavior/ http://forums.odforce.net/topic/17758-normalizing-and-unnormalizing-transform/ Don't reference parameters that are using local variables. There are couple ugly solutions in the topics above, but if you are just starting I would remove the local variables and click Move Centroid to Origin.
