  1. Where is Measure Concave in H17.5 ?

    Thanks James ! I hadn't understanded that negative value of curvature that points to concave. It is exactly what I wanted.
  2. Hi. I want to re-fracturing my debris by voronoi depending on concave, but H17.5 measureSOP don't have curvature type "concave". ( there was it in H16). where did he go? Is there an alternative method?
  3. Thanks willow! That node can give me more good result. It can't be compiled because of attribute transfer so it's quite slow in my large scale destruction simulations, but it seems to be one of the good solution.
  4. It was my blind spot! Thanks Joseph. Deforming their mesh by active is certainly good for alembic. From the point of view of data size, problem remains because that deforming geometry can’t be outputted packed alembic geometry. Anyone have static mesh idea?
  5. Hi.I have been looking for a good edge detail way for Houdini destruction vfx. For Destruction, pieces are created by Voronoi split, but the straight cutting line is not good looking. EdgeDetail of RBDmaterialFracture node solves this, but it is very unstable for small or complicated geometry. Boolean-based segmentation (cutting) method is also less stable. so I want to distort the edges formed by Voronoi segmentation.And I don't want to use the shader-based method too much. The only way I found was https://vimeo.com/178206035, which is fast and stable, but for most geometries it forms strange polygons that don't fill tightly and can't keep the original geometry looking. This can be solved by the trick of TransformPieces only when the Lowres fragment moves by Sim, but the whole topology changes drastically, so it becomes very heavy if transferred to other software through Alembic etc. Motion blur is also difficult (especially not compatible with c4d) The problem of UV distortion is also serious. See the file for details of the problem. Does anyone know Edgedetail's method for a good Voronoi split that fills the gap exactly? edgedetail.hiplc
  6. Hi,HoudiniEngine was able to load and avoid this problem by digital assete Houdini Alembic node, but this way seems to be very slow ... Please let me know if there is better way.
  7. Hi.Now I want to use cinema4d to composit character to houdini vfx and render these,by alembic pipeline,ut my cinema4d has serious problem about importing alembic. When I export the object by my standard fragmentation network as Alembic, Cinema4d seems to recognize it as a null object Therefore, it can not read geometry. The problem seems to be on the Cinema4d side because the geometry was read correctly in Blender, but changing the settings for some nodes in Houdini will also cause the Cinema4d to read properly. However, the trouble is that there are multiple nodes that might be the cause, that the behavior changes due to continuous parameters such as ScatterPoints, and that even if another primitive is put into this network, the behavior changes. Chaotic situation is born. Is there a solution on Cinema4d or Houdini for this Alembic import problem? Help me. Houdini lndie 17.5.173 Cinema4d studio R20.059 alembicBug.zip
