I find QuickThickness (on rray) to be pretty reliable.
You'll need to flip the normals on the inside surface but it avoids self intersections and remains parallel (as long as you're not adding too much thickness for the topological layout of the points). http://traypen.com/rr/bak/eistan/quickThickness_v1.6.xsiaddon On 12 December 2016 at 15:50, Christopher Crouzet < christopher.crou...@gmail.com> wrote: > Have you tried using `AttribTransfer SOP` to transfer the UVs from the > original mesh onto the output of the node 'polyreduce1', and then merging? > > > On 12 December 2016 at 22:41, toonafish <ron...@toonafish.nl> wrote: > >> you could try Meshmixer, it’s free and used for 3D printing but has a >> “hollowing” feature that might work. >> >> -Ronald >> >> >> >> On 12 Dec 2016, at 16:25, Fabricio Chamon <xsiml...@gmail.com> wrote: >> >> ...well and minutes after writing the e-mail I found a really reliable >> solution in houdini, that is messing with vdb to smooth the internal part. >> The vdbsmooth op retains the nice sharp corners while reducing >> intersections, that is exactly what I want!
