paniruro Posted April 4, 2017 Share Posted April 4, 2017 (edited) Hi everybody, this is my first post. (I hope ·Effects· is the right place ) I'm trying a simulation fracturing object as Atom's video tutorial. (Font crumble with smoke and debris) I noticed that debris don't roll on the floor. How can i give them a smooth rolling effect? I hope some one of you can help me kind regards Pani. Edited April 4, 2017 by paniruro Quote Link to comment Share on other sites More sharing options...
vtrvtr Posted April 4, 2017 Share Posted April 4, 2017 (edited) Download https://github.com/qLab/qLib Subnet has a preset that does rolling debris It's not that I don't want to explain it, but it's not super trivial This might be an old method, the basic idea is to use the cross product of the velocity and someone other axis to create a proper axis system to rotate around. It's a very common technique in computer graphics even outside this particular effect Edited April 4, 2017 by vtrvtr 1 Quote Link to comment Share on other sites More sharing options...

vtrvtr Posted April 7, 2017 Share Posted April 7, 2017 I'm talking about the subnet sop. Just create one, click the little Gear in the parameter windows, you'll see a bunch of presets, one of them is called "Rolling-Debris" something Quote Link to comment Share on other sites More sharing options...
