Hi,

I have a scene where an object is tracked to some points on a dynamic cloth object.

In the viewport when scrubbing, it seems to track fine and correct itself if it’s slightly off. However in renders, the attached object is slightly delayed – almost like it’s animation is being tracked a frame or 2 behind the cloth dynamics.

In my original project…

Hi,

Thanks but this was not suitable as it’s a cloth animation that needs to be followed.

I did however figure out a way for anybody interested.

I used the 4 points to get my central position null. I then attached nulls to the front and side points. I then used a target tag on my middle position null so it would track the side null, finally I put…

Thank you Kouraib,

For more context, the cloth simulation tube waves around and needs to have a sort of object aligned to the top of it while it moves about.

Here, this may help get my idea across more: https://drive.google.com/file/d/1Mhbp4nlyvb-jQmX-stv2CZHbLQLUbRo4/view?usp=sharing

See how the cube is positionally tracked perfectly using my…

Slight update.

I’ve gotten the position to track exactly as I need, but cannot figure out how to get the rotation to follow.

Method used for position: Xpresso ‘Point’ node is taking the positions from 4 points using point index > Pushing those into Vector2Reals to split into X, Y and Z > Adding up all values from each axis then dividing them by 4 (4…

Hi Kouraib,

Thanks for the quick response!

Thanks to the info you gave me, I have successfully created the point at the centre of the top of the tube. Do you know how I would then go about attaching a Null to that point? I’ve had a google, been messing with constraint tags and attempted expresso – but cannot work out how to get it to connect and…

Hi,

I have a cloth simulation of a tube using a bunch of wind modifiers and turbulence to get the look I am after. I’m finally at a point where I think it’s looking good.

I need to attach an object to the top of the tube, but still have it track with the wild turbulent movement. Does anybody know a way to grab the position of for example 4 points…
