KenBee Posted October 2, 2020 Share Posted October 2, 2020 Hi everyone, I am learning vellum right now, and I made a simple set up of a rope falling down with vellum and I really liked the look of it. But when I applied a wind on it, the rope started stretching, I was wondering how I can make the rope look tighter without any stretching. Thanks in advance! vellum_noStretching.hipnc Quote Link to comment Share on other sites More sharing options...
Noobini Posted October 2, 2020 Share Posted October 2, 2020 start again, don't use a box...simple line, feed that into vellum as a string. Quote Link to comment Share on other sites More sharing options...
KenBee Posted October 2, 2020 Author Share Posted October 2, 2020 are there any other way to do it? I wanted to apply it to a pirate ship model, where the rope come in as cylinders already. Quote Link to comment Share on other sites More sharing options...
Noobini Posted October 3, 2020 Share Posted October 3, 2020 if you're stuck with what's given to you, then struts. There's intersections here...but it's just an illustration, someone will have to do cleanups. vu_RopeFromCyls.hiplc 1 Quote Link to comment Share on other sites More sharing options...
Sustaxata Posted October 3, 2020 Share Posted October 3, 2020 it makes a lot of sense to try to make this rope into a line and sim it as "hair" You can try to set something up with the shortest path sop and find star/end points with group by open edges Quote Link to comment Share on other sites More sharing options...

KenBee Posted October 7, 2020 Author Share Posted October 7, 2020 my rope is gonna get compressed and it is going to be following the ship moving, which is why I used attach to geometry. I was using the setting below but it is still stretches a lot, with just wind velocity 10, substep 10, constraint iterations on 1000. I wonder if more constraint iterations is the only to go if i want it to stretch less. Quote Link to comment Share on other sites More sharing options...
charly Posted October 7, 2020 Share Posted October 7, 2020 Hi, I would like to know if there is a way to animate de pscale attribute during the simulation. If I do so, the lenght of the rope is scaling up, but I'm wandering if there is a work around. Thanks Charly Quote Link to comment Share on other sites More sharing options...
