Krion Posted July 1, 2018 Share Posted July 1, 2018 (edited) Hello there. I am fairly new to Houdini and animation. I have done the "create reference copy" command on one edge loop/polysplit node, and i would like to edit the expression on the copy's "edge percentage" parameter so that it has the inverted value of the node that it is referencing. So that when it's (for example) 0.8 on the original node, it's 0.2 on the reference copy. How is this done? In other nodes it could be the rotate parameter. That when it's 90 on the original it's -90 in the referenced node. Thanks in advance. Edited July 1, 2018 by DévinOdforce Quote Link to comment Share on other sites More sharing options...
toadstorm Posted July 1, 2018 Share Posted July 1, 2018 just change your expression to handle the inversion. for example, if you want to change a 90-degree rotation to -90, then change your expression to -ch("../some_node/rx"). for something like your percentage example, just use 1 - ch("../some_node/edge_percentage"), or whatever the channel name is.
