I have a little problem with interior surface color after voronoi fracture - it's black. This is what i did not understand:
I've been following tutorial about fractures, and it's about smashing pighead test geo. Here's a simple walkthrough:
1. Geometry - pighead, with shader
2. isoofset - to get scatter points for voronoi inside the geo
3. scatter node
4. voronoi node
So, in doing so and with everything set to default (beside scatter points count), i get interior surface black (example in attachments).
However, recently i found another scene file for the exact tutorial (on this forum for another unrelated to this question issue). As i understand it was made in a previous Houdini version (mine is the latest to date, 17.5.391), and some parameters in nodes are different (it's cool that Houdini is able to load those ‘obsolete’ versions of same nodes with their parameters). When i copy those old nodes from there into my scene, i am able to get white surface color. By trial and error i was able to figure that this issue is due to some changes in Voronoi fracture node.
I have 2 questions:
1.What is that black color? Is it some missing shader (and if so, why is there no issues with old Voronoi fracture node?)
2.How can i achieve white color without using old node from old scene file?
I attached scene file with hopes that someone will be able to see it with the same result as i am.
Thanks in advance!
ps. I thought possibly this was due to a bug, so i updated Houdini to it's latest version, no effect.
