hi_dini Posted August 8, 2019 Share Posted August 8, 2019 (edited) Hi guys, I'm trying to make something with Vellum system but now suffering some problems. What I wanna make is, Pin point group is disabled after 30 frames. I tried to use switch SOP node and to control 'group_pin_src' node in Vellum cloth Sop node. It didn't work and I think I should try it in Vellum solver node. but I don't have any idea with this node. Give me some helps please ! Here's my hip file vellum_Pin.hip Edited August 13, 2019 by hi_dini Quote Link to comment Share on other sites More sharing options...
Jesper Rahlff Posted August 8, 2019 Share Posted August 8, 2019 the problem is that if you disable or remove the grp, vellum will try to look for a group that does not exist. Instead what you want to do is preserve the group the whole time but remove the points in the group. So in a point wrangle you can do something like this: if (@Frame > 30 && @group_pin ==1) { @group_pin = 0; } Quote Link to comment Share on other sites More sharing options...

When I check geometry solver of vellum solver, group:pin changed successfully but, simulation doesn't change. I think this node in Vellumcloth SOP node affect to pinsrc value and It caused this problem. but It isn't updated anymore TT Quote Link to comment Share on other sites More sharing options...
Yader Posted August 11, 2019 Share Posted August 11, 2019 If you set your Pin Type to Permanent, the mass of your pinned points are set to 0.0. All you have to do is to set them at the mass all the other points have at Frame 30. One way: You could dive into your vellum solver setup, put down a pop wrangle, set your group to pin, activate at $FF>30 with mass = 0.1; and your pins are good to go Quote Link to comment Share on other sites More sharing options...

I had never thought about controlling the mass attrib Thank you for reply, Solve this. Edited August 13, 2019 by hi_dini Quote Link to comment Share on other sites More sharing options...
