Mesh Deformer lagging 1 frame behind with simulation
I have tried to change hierarchy, but nothing I do so far can stop the 1 frame lag for rigid body dynamics.
I even tried a simple sphere object with mesh deformer set to a cube.
The cube then has a rigid body tag.
I have 1 frame lag in the viewport, and when I wiggle the mouse, the lag jumps to the present. However, with my IPR window (Arnold), the render also shows the lag behind which only corrects in viewport and render when I move the mouse.
I moved the cube object below the sphere in the object manager, but the result is the same.
What am I doing wrong?
I am on C4D 2025.1.1, but I don’t see this as a bug fix in any recent patch.
It even occurs when I cache the rigid body.

Hi Eric,
Cinema 4D scans the objects from top to bottom so rearranging can solves the problem in some cases,but I think that when you rearrange the objects in the Object Manager, you could also using the Shift Priority tag, this may fix the delay problem. You could also get information that may be useful to you about the priority by right-clicking on Priority and then Show Help, if the problem persists you could post your file here so that I can check it for you.
I hope this is useful to you.

I tried both of those, and the object with the mesh deformer still lags behind 1 frame from the dynamic object.
This is the simplest scene with just two objects. Can you replicate and get the same result?

You’re right, I just wanted to make sure we’re both dealing with the same situation. I’ve tried several methods but to no avail until I calculated the cache. It seems to that be necessary to make the mesh deformer sync with the tag simulation. I hope this helps.

When I tried to cache, even that didn’t help. I still had the lag.

But the cache fixed the problem for me, have you watched the screen recording?
