Where is my mistake? since the file seems to work and your "infection" spreads from start point within the painted shape I'd consider it working if it doesn't work as you want it to maybe it will help if you describe how you actually want it to work Quote Link to comment Share on other sites More sharing options...
Noobini Posted January 28, 2020 Share Posted January 28, 2020 (edited) it's because mountain doesn't work on a set of points. try this simple test, Grid, mountain, works perfectly fine. Now scatter points on the grid and feed that into same mountain....mountain refuses to work. here's one way to get around it, 'surface' it first with tri2D..then add to convert them all back to points....I'm just guessing at what you really want...dunno. vu_infection_2_mod.hiplc EDIT: I think in my groupexpression @Cd.r>0, use @Cd.r>0.1...it's more accurate I think. And I'm not too savvy on the actual infection algo...if your question is more about this rather than the mountain, then I really don't know.

anim Posted January 28, 2020 Share Posted January 28, 2020 ah, it was about the mountain node, in that case just add Normal SOP in Point mode before Scatter SOP so that your points have N attribute that Mountain can use 1 Quote Link to comment Share on other sites More sharing options...

Follyx Posted January 29, 2020 Author Share Posted January 29, 2020 ok,sorry. unfortunately i uploaded the wrong file. Would you mind to have a look onto the right one? infection.hip Quote Link to comment Share on other sites More sharing options...
Sepu Posted January 29, 2020 Share Posted January 29, 2020 It is working fine here - you aren't seeing the color because you have the grp in the wrangle which isn't updating. You can see the attrib is getting updated, so you do not need the grp there. Quote Link to comment Share on other sites More sharing options...
Follyx Posted January 30, 2020 Author Share Posted January 30, 2020 ok that was the goal with the group node. But why it will not infect the whole grid area? Quote Link to comment Share on other sites More sharing options...
