tveda Posted September 17, 2014 Share Posted September 17, 2014 Hi everyone I was wondering if anyone has suggestions of how to achieve / setup a thickness / twist control for sweeped objects. I've been digging for solutions and haven't found a solid solution yet, any insight is appreciated. Thanks Tim Quote Link to comment Share on other sites More sharing options...
MrScienceOfficer Posted September 17, 2014 Share Posted September 17, 2014 I don't believe the sweep sop has controls like that, not per copy controls I mean. You need to use a copy sop and then you have a slew of attributes you can use. http://www.sidefx.com/docs/houdini13.0/copy/instanceattrs Quote Link to comment Share on other sites More sharing options...
tveda Posted September 17, 2014 Author Share Posted September 17, 2014 i thought i had seen a way to apply the attributes to the curve (backbone), and they then transfer over, using vop sop ramps to control them. I'm just wondering if there is any good insight on how to do that, the setup that is. Quote Link to comment Share on other sites More sharing options...

tveda Posted September 18, 2014 Author Share Posted September 18, 2014 Oh wow, thanks pazuzu, so those options are already made within the sweep tool, and just activated by editing the parameter interface? Quote Link to comment Share on other sites More sharing options...
Pazuzu Posted September 18, 2014 Share Posted September 18, 2014 The nice thing about the sweep sop, its that it can evaluate per point attributes so you can use in this case the point number and the total number of points to use it as lookup for a ramp, to then control some native parameters of the node.

Robert Posted September 19, 2014 Share Posted September 19, 2014 (edited) Those options are not available by default in the sweep SOP. Pazuzu added them himself and uses them to control the roll and scale. The amount of roll and scale is taken from the ramp parameter and not from the backbone, it's not transfering any existing attributes. If you need control based on already existing attributes from the backbone you need the copy SOP with its stamp function and add and manipulate the N and up attributes by yourself to control the orientation. Though if you are creating attributes the same way they are created now with ramps, obviously the extra step to transfer them over isn't needed and the sweep that Pazuzu provided will be enough.
