blackchicken 16 Posted March 5, 2021 (edited) Hello guys. I found strange behavior in bullet. I have medieval wooden cart, full of heavy stones, moving fast from the hill. By default, bullet have 10 substeps, should be good enought. Cart is rigged, and it is deformed, twisted so I need him as deforming static object. If I check cart with timeblend, frame increment 0.1 in SOPs, I can see slight movement of geo, dive to DOPs, bullet stones fall, but my cart, deformed static geo is jumping on full frames. No movement inbetween frames. That causes ofcourse incorect collisions and all kind of bad things. I tested in H18, H18.5 same results. So I never had collision geometry substeps??? Is there some easy fix, how to force bullet recompute deforming static object every given substep? Thanks a lot. Edited March 5, 2021 by blackchicken Share this post Link to post Share on other sites
blackchicken 16 Posted March 5, 2021 Ok we found it. If you use timeblend , interpolate quaternions and transform must be on for packet object. 1 Share this post Link to post Share on other sites
