Lyonz Posted June 10, 2010 Share Posted June 10, 2010 (edited) When you use a facet sop with cusp edge option it harderns the edge but it also makes double points like the unique points option. If you do this to make an edge hard and then use the fuse sop to make it a seamless mesh it goes back smooth. Is there a way to make hard edges without making more points ? The method i was told is: Cusp Polygons with Facet SOP and Post-Compute normals AttribPromote SOP - Point Normals to Vertex Fuse SOP This has not worked for me and wondering how to solve this ? Thanks Edited June 10, 2010 by Lyonz Quote Link to comment Share on other sites More sharing options...
Dennis Posted June 11, 2010 Share Posted June 11, 2010 Hey, I just tried this and I think it's just a viewport thing. The Houdini Viewport uses the point normals to display the geometry, but as soon as you render your scene the vertex normals are used correctly.

Cheers, Dennis Hi Dennis, I have rendered my work and still getting the same problem, I have attached a file to show what im on about. The area with the hole in the mesh has nasty black streaks until i cusp polygons but when i fuse the points back it makes dark areas again.

anim Posted June 11, 2010 Share Posted June 11, 2010 you didn't promote anything with Attrib Promote, you need to fill in Original Name Parameter (N) but you need to create N attribute first to do that just check Post-Compute normals on facet sop here is modified file Seamless_Mesh_fix.hipnc Quote Link to comment Share on other sites More sharing options...

I wasn't aware of the angle parameter on the Faced SOP. Promoting the point normal to vertex normal and than fusing the points again. I love it!
