sdlovecraft Posted June 21, 2018 Share Posted June 21, 2018 (edited) Has anyone ever had a problem with primitives missing from using the findshortestpath node? This is the strange behavior I am observing. In the viewport the geometry seems to be present but this lack of primitives I have reason to believe is causing problems for the distribution of my scatter node that I am running on this afterwards.... Anyone have any ideas why this might be happening? Or ways to repair this? This is what happens when I try and scatter onto this geometry (Default settings, relax iterations on 10). This is being created from some very normal looking, repaired and remeshed geometry to me: I would link a Houdini file, but I'm not sure how to embed my geometry into the file... Thanks Sam Edited June 21, 2018 by sdlovecraft Quote Link to comment Share on other sites More sharing options...
ikoon Posted June 21, 2018 Share Posted June 21, 2018 You can use the Stash SOP to embed the geometry into .hip http://www.sidefx.com/docs/houdini/nodes/sop/stash.html Quote Link to comment Share on other sites More sharing options...

Here is a super minimal .hip detailing the issue that i am having . missing_prims_pathfinder.hip Edited June 21, 2018 by sdlovecraft Quote Link to comment Share on other sites More sharing options...
ikoon Posted June 21, 2018 Share Posted June 21, 2018 I assume that you mind, that in the upper region, there are more points scattered. That is because of the "coincident" shortest paths (primitives) being in the exact same position. I don't know the algorithm of Relaxation of Scatter SOP node, but it seems that it doesn't take into account coincident positions on different primitives. I tried to remove coincident primitives. I followed the link by tamte ("Anim" here on odforce) and added Convertline SOP, Fuse SOP, PolyDoctor SOP and I attach a proposal of solution. https://www.sidefx.com/forum/topic/54451/?page=1#post-244403 missing_prims_pathfinder - v1.hiplc Quote Link to comment Share on other sites More sharing options...
Noobini Posted June 22, 2018 Share Posted June 22, 2018 not sure if I understood the problem but just some observations: 01) you're using the old group ? dunno why. 02) in your end selection...it has 1 of 5...is this deliberate ? if you have 1 of 1 then it selects all points...and you'll get the 'missing' ones you're talking about ?

Noobini Posted June 22, 2018 Share Posted June 22, 2018 here's my go...I've used the orig end selection 1 of 5... missing_prims_pathfinder_vu.hipnc Quote Link to comment Share on other sites More sharing options...
sdlovecraft Posted June 22, 2018 Author Share Posted June 22, 2018 you people are amazing! thanks so much for helping! I used the first solution to fix my problem . I am going to go through these other responses and answers after work today to learn Quote Link to comment Share on other sites More sharing options...
helloiamramon Posted September 12, 2018 Share Posted September 12, 2018 Hi there, thank you for this post I had the same problem that have Sam but also I don't know how to create a nice mesh from my shortest path (like f.ex. the tirth image of Sam's first post) Probably is a dumb question, but indeed I pretty dumb hahaa Thank you in advance Quote Link to comment Share on other sites More sharing options...
