Houdini7 Posted July 5, 2017 Share Posted July 5, 2017 (edited) Hi, i wanted to use the Facet SOP on a certain selection of points. The node network looks like this: The group parameters are as follows and select four points. The Facet SOP parameter are as follows: Every option I select in the Facet SOP (e.g. Make Planar) effects all points and not only the selected points. Has anyone an idea why ? Thanks in advance Edited July 5, 2017 by Houdini7 Quote Link to comment Share on other sites More sharing options...
vtrvtr Posted July 6, 2017 Share Posted July 6, 2017 Yeah, I suppose the algorithm used to calculate the normals runs through the whole geometry regardless However, you can simply use the group in a wrangle just below to zero out the what you don't want Quote Link to comment Share on other sites More sharing options...
Houdini7 Posted July 6, 2017 Author Share Posted July 6, 2017 @vtrvtr: Thanks. Hmm okay, seems like a big oversight. So it is not possible (without custom expressions) to change cusp angle or make planar locally on a specific group.How do you handle such situations in houdini ?

Houdini7 Posted July 6, 2017 Author Share Posted July 6, 2017 (edited) Okay I have found the solution. The Group Type parameter has to be "Primitives": Then the Facet SOP will take only the prims defined in the group. If you switch to "Points", then all points will be processed!
