Malcolm Zaloon Posted October 23, 2013 Share Posted October 23, 2013 Hello guys! I´m trying to use expression "rand($PR+$FF)" on "Second U" parameter, but i discovered that Carve node has no local variables as $PR (it´s a bug?) inspecting details node by node (with middle mouse button), i found that carve node has not preserving primitive group elements. in my scene in /geo/animation: object_merge1 has 27 primitives in copyGroup0 color1 has 27 primitives in copyGroup0 but... carve3 has 0 primitives in copyGroup0 (to insect i need disable "Second U" parameter to node cook correctly and i see cook result details) what i need is use $PR to randomize each primitive (curves) diferently. how can i do it? Workarounds? I seeking to use foreach alternativaly, but with no success. Help guys, i´m newbie on Houdini... i´m migrating from XSI ICE. thanks in advance, my example file attached.

Guest mantragora Posted October 23, 2013 Share Posted October 23, 2013 Use it with together copySop and stamp() expression. If you don't know how to use copySOP there are tutorials from PeterQuint and Sesi that covers that. Also, there are multiple examples here on odforce too. Looking at help page of carveSOP it looks that it doesn't support any local variables. Your file is not attached. Quote Link to comment Share on other sites More sharing options...
