eirik.m Posted February 28, 2012 Share Posted February 28, 2012 Good day friends! I have a mesh from Maya imported in to Houdini. The file format is fbx. And when I apply the voronoi fracture, voronoi fracture points and scatter, the mesh disappear. But in some earlier scenes where I have an imported mesh, it works fine. I have cross-checked the two scenes and there are no difference. When I remove the voronoi fracture points and only apply the scatter to the point input on the voronoi fracture node it works fine. So it seems the problem lies with the voronoi fracture points. I have also tried to connect the nodes in different sequences but nothing changes. It's so strange that it can work in some scenes and in some it does not. I'm sure there is a easy explanation to why this is happening Thank you very much!

Macha Posted February 28, 2012 Share Posted February 28, 2012 Greetings Eirik! What happens when you save your object as bgeo inside Houdini and then try to fracture it? Quote Link to comment Share on other sites More sharing options...
eirik.m Posted February 28, 2012 Author Share Posted February 28, 2012 (edited) Hello Macha! Thank you for the tip! I tried to export the geo via an rop driver. But unfortunatly it did not work. But it works when the geometry are made inside houdini and not imported. I'll try to cross-check the two scenes where it works even more Update: I see now that the scatter node can't send the points through to the voronoi fracture points. The scatter node creates 400 points but the voronoi fracture points have 0 points. Hmmmm, this is truly a mystery Edited February 28, 2012 by eirik.m Quote Link to comment Share on other sites More sharing options...
gui Posted February 28, 2012 Share Posted February 28, 2012 Hey Eirik, can you share the fbx for me to take a look? thanks Quote Link to comment Share on other sites More sharing options...

eirik.m Posted February 29, 2012 Author Share Posted February 29, 2012 it's a happy day! I found what's causing the problem. The meshes that worked where pretty large in sice. But when I scaled the meshes (that did not work) up, nothing happend. I then changed the resolution inside the voronoi fracture points and bumped up the points per area (the volume resolution where at default). Then The voronoi fracture points got the points sent from the scatter node, and it worked! So it seems that if the scale for the mesh is too small for the volume resolution inside the voronoi fracture points to read, it just disappear. I'm sure there is a more logicly explanation. But I felt church bells and a heavenly halleluja choir when I finally solved this mystery! I don't know for sure that this is the solution, but if I/someone ever comes over this problem again, there is less troubleshooting to do Have a nice day! until next time Eirik Quote Link to comment Share on other sites More sharing options...
