  1. I have a long, rectangular poly which ends up "folded" by 180 deg (not necessarily in half, as in the pic). After folding, this poly is obviously very non-planar. I want to add a new "crease" edge along the fold line to fix it. I can create the edge manually in the viewport, but I want a procedural SOP solution. The Divide SOP seems most logical (Convex poly: ON, Triangulate non-planar: ON), but it doesn't always work. Sometimes it creates a new crease edge, sometimes it doesn't (maybe because folding by 180 deg is so radical). Is there a SOP that would reliably do this? I see a "Crease SOP", but it doesn't create edges, it assigns weights to existing edges. PolySplit SOP could work, but the way you need to specify the split points (% of edge length etc) seems unnecessarily complex. I do have the 3D point positions of the fold line, so I can easily create a line there. But how do I "plug" it into the existing poly as a valid new edge?
  2. Object Fold Unfold

    Hello, Looking to make a similar effect http://www.tokeru.com/cgwiki/?title=Houdini#Unfolding_polys However, currently the effects works on faces (per-face) Is it possible to achieve the same but on islands or name attribute instead of face? Basically, the desired effect would be to unfold based on the color marked islands/groups. any suggestions or help please. Ipad_Cut.hipnc
