Hello, I am trying to create cracks in rock using polywire (and then boolean it with the rock geo). I am on Houdini 18.

However, the polywire doesnt seem to cover all the curves I have drawn. What am I doing wrong? I have attached a test hip file.

Also, if there is a better way to generate art directable cracks in a rock, I would be happy to hear your suggestions.

Thanks alot!

If you convert back to polygons after the carve it works - the conversion to bezier seems to knock things off. You might also want to fuse points from the different curves so the poly wire can branch.

if you ‘insist’ on using Bezier Curve, U Order 8 works.
