katosa Posted April 12, 2024 Share Posted April 12, 2024 (edited) I draw bezier curve and added polyframe node to get tangentu attribute, But I could not use @tangentu like @N in vex. Can I ask why "f@a=@N.y;" is ok but "f@a=@tangentu.y; " is not ok? Edited April 12, 2024 by katosa Quote Link to comment Share on other sites More sharing options...
tamagochy Posted April 12, 2024 Share Posted April 12, 2024 Try this f@a=v@tangentu.y; 1 Quote Link to comment Share on other sites More sharing options...
animatrix Posted April 12, 2024 Share Posted April 12, 2024 tangentu is not a known attribute like N so you have to use the actual attribute qualifier which is v in this case: v@tangentu. 1 Quote Link to comment Share on other sites More sharing options...
