Hash Fellow robcat2075 Posted January 15, 2019 Hash Fellow Posted January 15, 2019 It's been sitting there for a year now but I've never tried Bullet Soft Body Dynamics. It works very well! Here is the PRJ if you want to try. RubberDonuts05 unsimmed.prj in the Chor and Choose simulate Bullet DonutDropAO1500.mp4 2 Quote
Admin Rodney Posted January 15, 2019 Admin Posted January 15, 2019 Thanks Robert. I needed that! Quote
Hash Fellow robcat2075 Posted January 15, 2019 Author Hash Fellow Posted January 15, 2019 It's a bit like cloth in that denser meshes can be floppier. Sometimes slightly different settings can get very different results, so you have to experiment. So far, I haven't detected that "Bounce" changes much Quote
Admin Rodney Posted January 15, 2019 Admin Posted January 15, 2019 This isn't 'soft' bullet but thought I'd post it here as it started as a soft but then I adapted it to solid. Quote
Admin Rodney Posted January 15, 2019 Admin Posted January 15, 2019 Breaking the glasses was easy enough with soft bullet. Getting it to settled down... still working on that. 1 Quote
Wildsided Posted January 15, 2019 Posted January 15, 2019 Nice one Rodney. Although to come apart like that they have to be the most cheaply made pair of spectacles ever. Shoulda gone to Specsavers. Side note, I wonder if we could make a flowing hair simulation out of the soft body sim. Quote

steve392 Posted January 18, 2019 Posted January 18, 2019 that's working very well like to try it with a charector Quote

steve392 Posted January 19, 2019 Posted January 19, 2019 Ive tried tom dropping on another character but got a bit carried away and killed AM lol will try again later this is interesting stuff Quote
Hash Fellow robcat2075 Posted January 19, 2019 Author Hash Fellow Posted January 19, 2019 I'll note that turning on "Volume Preservation" in the Bullet Soft Body constraint generally makes things look better. Quote

Hash Fellow robcat2075 Posted January 21, 2019 Author Hash Fellow Posted January 21, 2019 That is amusing! How did you end up saving that in 3gp? Quote
steve392 Posted January 22, 2019 Posted January 22, 2019 I saved as AVI but that was a large file so I used AVG video editor to change it thinking I had it set for mpg 4 a nice small file have no idea what 3gp is lol Quote
pixelplucker Posted January 25, 2019 Posted January 25, 2019 Does bullet dynamics work with blob generator? Wonder if you could simulate liquids with it. Quote

ruscular Posted April 8, 2019 Posted April 8, 2019 I am very please on how fast it simulate and results were good with the example project file posted. Can you assign the bullet to a weight map or set of points that you want to be effected? Quote

I don't know either way, I had only just gotten Newton dynamics figured out then... POOF... out with Newton in with Bullet! I don't know enough about Bullet to know if the parameters are behaving like they should or if a bug report is due for something. I'm hoping someone will investigate Bullet more thoroughly than I have had a chance to do and report to us. Maybe that person can be you! 1 Quote
ruscular Posted April 8, 2019 Posted April 8, 2019 This is bullet from lightwave3d for a breast bounce setting using a weight map as deforming parts effected. I played with several setting and reset dynamic simulation each time getting very little differences of the bounce. I hope the next version of AM: will include more settings that can adjust volume preservation and shape retention. those 2 dials really effect the outcome of the simulation. Also the shape lock settings keeps the simulation lock to the nearest edge of the effected parts. Mind you that these setting in lightwave are a tad touchy as for stability. I can understand why AM: didn't include them, as for the simulation in here is fast and hasn't crash. I didn't find a way to assign the bounce to parts of the model. I did love the way AM: rigging system can add a spring to the skeleton and has enough settings to alter the spring and even add smart bone to the spring bone. It is my hope to rig a female character in AM: with spring bone and then export it to lightwave and use deforming parts bullet effect to the area that I want effected. Quote
Hash Fellow robcat2075 Posted April 8, 2019 Author Hash Fellow Posted April 8, 2019 Here is a test (v19i) showing different bounce stiffness settings. My guess is that Soft Body settings are model-wide only in A:M L to R: 0.05... 0.01... 0.005 PRJ: RubberDonuts05b Three Bounces.prj (To simulate, choose the Chor>RMB>Simulate Bullet) DiffBounces.mp4 Quote
ruscular Posted April 9, 2019 Posted April 9, 2019 I didn't know I could go lower than .01 in the settings. It looks so much better like jello at .01 and the collision is really accurate and stable. Next step is get them to release a new version with parts deforming with Bullet! Quote
Hash Fellow robcat2075 Posted April 9, 2019 Author Hash Fellow Posted April 9, 2019 Ruscular, what does it mean on your screen capture where is says the "Volume conservation" is 110%. I'm wondering how it could conserve volume any more than 100% which would already be completely conserved. Quote
ruscular Posted April 10, 2019 Posted April 10, 2019 I was trying to inflate it I dont know if it did that, but it didn't hurt! LOL I should try for 200% and see what happens. It was my Spinal Tap moment! Quote
