nemsi Posted August 23, 2021 Author Share Posted August 23, 2021 What I get is just crazzy rotation... Quote Link to comment Share on other sites More sharing options...
flcc Posted August 23, 2021 Share Posted August 23, 2021 (edited) I think you need to use a solver. Currently rotations does not accumulate. Angle is an absolute value. When @progressive decreases, the motion reverses and the rotation returns to zero. Probably what is causing the "crazy rotations". Also the rotation value is very high. almost one turn per frame for some points. But I am not sure what you are trying to achieve. Here is still a modified file with rotation stopping smoothly, but probably not what you want. At least the problem is more obvious.

nemsi Posted August 24, 2021 Author Share Posted August 24, 2021 Hi Flcc, thank you for taking time with my problem. Dealing with rotation in houdini is really headek!! It needs more tweeking/work to get something soft I agree. Your exemple seems to be the same as mine no? I can get the difference.. Quote Link to comment Share on other sites More sharing options...
flcc Posted August 24, 2021 Share Posted August 24, 2021 Yes it's slightly the same, just the problem is more visible. But depending on what you are trying to achieve, I'm not sure you're on the right track. So many way to make things in houdini. Quote Link to comment Share on other sites More sharing options...
nemsi Posted August 24, 2021 Author Share Posted August 24, 2021 Hi Flcc, what i'm looking for is to get roating instances that get stopped smoothly in an area zone. I guess attribute transfer was the best start to get the area zone. The main problem is to interact with a rotating instance to make it slow till it stop when in the area.. many way to do it i guess but i cant get the right one Thank you.

flcc Posted August 25, 2021 Share Posted August 25, 2021 Here is an example with the sop solver. I'm pretty sure you can also do it with MOPs Orient_fading F.hip 1 Quote Link to comment Share on other sites More sharing options...
