octaviuz Posted October 31, 2013 Share Posted October 31, 2013 Hi! houdini newbie here, i use Real Flow a bit so am trying to do meshing in houdini, is pretty good so far, if a bit slow compared to Frost in 3dsmax. i got a Rf_particle_import -> Particlefluid surface -> group -> smooth the smooth wont affect the geometery, if i save out the surface as bgeo or obj then groups->smooth works fine Is there an op i need to have to be able to use smooth? saving geo out then reloading is a bit cumbersome as i want to tweak settings on particlesurface and also peak... thanks in advance and excuse my lameness Octavio Quote Link to comment Share on other sites More sharing options...
dobin Posted October 31, 2013 Share Posted October 31, 2013 smoothing dosn't work on polygon soup if you choose to generate one on the Particlefluid surface. and any reason to not use filtering on Particlefluid surface itself? Quote Link to comment Share on other sites More sharing options...
Guest tar Posted October 31, 2013 Share Posted October 31, 2013 also use the VDB surfacing workflow if you can, you can see it in Flip Fluid shelf tool. It should be faster. Hope it works for RF points Quote Link to comment Share on other sites More sharing options...
octaviuz Posted October 31, 2013 Author Share Posted October 31, 2013 marty: thanks for the tips, will have a look at VDB surfacing. dobin: i am using filtering but it smoothes out bigger details (drop / tendrils) too much, so i have it on low-ish values, the smooth op i am trying to affect higher frequency bumps. i found out the if i drop a pointjitter op (scale=0) the smooth op works fine! go figure Quote Link to comment Share on other sites More sharing options...
edward Posted October 31, 2013 Share Posted October 31, 2013 Also check out the VDB From Particle Fluid SOP in H13. Quote Link to comment Share on other sites More sharing options...
Solitude Posted November 1, 2013 Share Posted November 1, 2013 I don't think it's be changed in 13, but also add a facet sop and set it to "post-compute normals" after the smooth sop if you haven't already. I used to think the smooth sop was broken, but it doesn't update normals. Quote Link to comment Share on other sites More sharing options...
Guest tar Posted November 3, 2013 Share Posted November 3, 2013 (edited) Also check out the VDB From Particle Fluid SOP in H13. This is very cool! 2x+ the speed compared to 12.5 on a simple test. OsX10.9. H13 vdb fluid surfacing= 1.29min H12.5 vdb fluid surfacing = 3.25min 12_5 fluidTesto_to13.hipnc.zip Edited November 3, 2013 by tar Quote Link to comment Share on other sites More sharing options...
