Marcocheng Posted November 8, 2019 Share Posted November 8, 2019 Hello folks! I have a pre-fractured piece which is a watertight mesh (from the previous simulation) and cutting plate (grid with noise) and planned to do a secondary fracture. Direct boolean fracture is failed to cut them apart. Meanwhile, when I VDB remesh the pieces before boolean fracture it works like a charm. Here's the network. Fracture result: LEFT(VDB remesh before shatter): The cutting is working as expected. Mid(Regular remesher before shatter): The cutting is not working at all. Right (Original pieces): The cutting is not working at all. I tended to use the original pieces as I want to have the original UVs. But the fracture is failed. Any tips to prepare pieces to fit into boolean shatter tools? What's actually causing the problem here? Thanks!

vicvvsh Posted November 8, 2019 Share Posted November 8, 2019 Hi, the problem is that this original piece is not watertight geometry, look carefully at it. Find the causes of this in first fracturing and fix them. Quote Link to comment Share on other sites More sharing options...
Roznick Posted November 10, 2019 Share Posted November 10, 2019 As vicvvsh pointed out, your geometry probably isnt closed. I had a similar issue white doing a shatter on an impoted 3d scan. For me, a combination of Clean and Fuse SOPs fixed it. Quote Link to comment Share on other sites More sharing options...
