Fyre Posted February 8, 2017 Share Posted February 8, 2017 Basic question, I'm trying to change the floor value of a sine wave but there dosn't seem to be any clear options to adjust it from being a symmetrical sine wave: between -1 and 1. I'm looking for something like -10 and 1. Thanks Quote Link to comment Share on other sites More sharing options...
Atom Posted February 8, 2017 Share Posted February 8, 2017 Play around with Limit and Math nodes. Then Math node has a range TAB for remapping your values into a new range. Quote Link to comment Share on other sites More sharing options...
Fyre Posted February 8, 2017 Author Share Posted February 8, 2017 (edited) Thats brilliant thanks very much. Kind of a weird way to think about it, its not straight forward numbers. Is it possible to get a curve on the adjustment? If I leave the limit with a curve and adjust the fit on the math node, the top and bottom values move equally, only if there is a constant zero does the fit have an effect (which makes sense I guess). But what If I needed a rounded sine? Edited February 8, 2017 by Fyre Quote Link to comment Share on other sites More sharing options...
vtrvtr Posted February 8, 2017 Share Posted February 8, 2017 Personally I think the most robust way to fit values in chop is using the icmin/max function. It preserves the curves and you can work with absolute values and it's only one node. It's so useful I even recommend you making a preset for it. It might have some pitfalls, but I'm yet to find any.
