Screenglow VFX Posted January 25, 2017 Share Posted January 25, 2017 hi guys ! what would you choose as the best way to cut geometry ? with the cookie sop I need to tweak a lot of parameters to get where I want.Maybe I am missing something tks Quote Link to comment Share on other sites More sharing options...
old school Posted January 25, 2017 Share Posted January 25, 2017 Wait a couple weeks... H16 will have an answer for you that still blows me away every day I use it. In the meantime, yes Cookie needs a lot of love to get results in some cases. Always try jitter parameter first. Cookie also has issues when the geometry is too small (less than 0.01) or large (greater than 100) so scale in to the sweet spot of 1 to 10 overall units. It also doesn't like co-incident surfaces hence jitter. Always put the more complicated geometry in to the left first input. Really try not to slice up a manifold left input geometry with an open grid plane and instead use a box to cut the geometry using only one of the faces of the box as the cutter. Always make sure primitive (not point normals as they simply do not matter but check the primitive normals) are always facing outward or else use a Reverse SOP to make sure they are facing outward. We gave up on Cookie when doing the shatter tool as it was unpredictable. Shatter Tool uses recursive Clip SOPs to cut up the geometry reliably.

harryorford Posted February 26, 2017 Share Posted February 26, 2017 Could it be done using FEM? Quote Link to comment Share on other sites More sharing options...
