Andrea Posted August 14, 2018 Share Posted August 14, 2018 Hi! Here is something I've been working for a few time on and off. I was searching for something that I could use for plants that are colliding near the camera. So I ended up using the bullet solver with packed geometry. I'm not sure if it's the right way to go for this kind of things but at least I learned a lot about the constraints. Thinking afterwards I probably should have used a few more substeps but I hope you can enjoy it anyway! Suggestions for improvements are welcome 9 Quote Link to comment Share on other sites More sharing options...

Jesper Rahlff Posted August 17, 2018 Share Posted August 17, 2018 Would love to dig through the system if you are willing to share a file. Quote Link to comment Share on other sites More sharing options...
Andrea Posted August 18, 2018 Author Share Posted August 18, 2018 Yes I can. I was also going to write a short explanation/reminder on my website, but I need to clean it up a bit 1 Quote Link to comment Share on other sites More sharing options...
ThomasPara Posted August 20, 2018 Share Posted August 20, 2018 I think this is the right way to go. We use bullet aswell on trees and foliage, great for interaction with other objects (since grain and wire is a bit to unstable). You can set rotational stiffness on the rbd objects to make it more bendy. Now it looks a bit dry. Quote Link to comment Share on other sites More sharing options...
Andrea Posted August 21, 2018 Author Share Posted August 21, 2018 Probably here I could have used wires for simulating the branches since they are essentially splines. But in the past I've done some trees simulation with them and I spent most of the time making little changes in the wires parameters for avoid them to get stuck in walls or each other. At the same time I have to say they were really good and easy to use in the scenes were the trees had not much movement. Anyway some people made some amazing plant simulations in Houdini with wires so maybe there are some nice tricks that can be used. Thanks for the tip. If I have the time before moving (&co) I'd like to try change the rotational stiffness and see the difference Quote Link to comment Share on other sites More sharing options...
tamagochy Posted November 17, 2018 Share Posted November 17, 2018 Any chance to get a scene? Quote Link to comment Share on other sites More sharing options...
