MAYA_ Posted June 18, 2018 Share Posted June 18, 2018 Hello Houdini people Has anyone ever had funny results when emitting flip from cached geometry? I am having some object fly around my scene (they are just geometry instanced onto points). When emitting flip from them, it behaves weirdly, not like the same emission from the same objects (animated instead of simulated) is. I am wondering why this might be and if it has something to do with the velocity or maybe substeps. I tried adding more of the latter and adding a timeblend but it does not seem to fix it. I am grateful about any input! Quote Link to comment Share on other sites More sharing options...
MAYA_ Posted June 18, 2018 Author Share Posted June 18, 2018 Alright, so I have figured out that the velocity is the problem. I tried to delete all velocity off the cache and recalculate it using a trail sop but for some reason it doesn't give me the same results as it does for the hand animated geometry. I get weird negative numbers and extreme high values for some points. Quote Link to comment Share on other sites More sharing options...
wvonjess Posted June 18, 2018 Share Posted June 18, 2018 Hey, It probably is due to lack of subframes on the animation. Quote Link to comment Share on other sites More sharing options...
evanrudefx Posted June 18, 2018 Share Posted June 18, 2018 I believe I have had similar problem and I fixed it using time blend. Quote Link to comment Share on other sites More sharing options...
