So this scene file contains a blank alembic file with a tag. The tag has python code that you can save as a preset or whatever.

Just import the first file in an alembic file sequence and move the tag onto the object.

MAKE SURE that the file sequence has absolutely no padding for the numbers. The number must start at 0.abc and not 00.abc or…

I actually found a python script to make a tag that allows C4D to recognize alembic sequences and display them properly.

Let me know if you need it, too. It is fairly easy to use.

Thank you for that.

The only thing is, if my sequence is like 200 frames, then I don’t want to have to keyframe all frames to appear at the appropriate frame in the timeline.

I thought there would be a way to import the sequence and have it run as one file.

For Arnold in C4D, there is a Arnold Procedural object that can load the alembic sequence by…

Ok, so apparently I can just use vdb if I use the c4d volume loader and mesher to create a mesh.

I really thought I needed to use Arnold Volume for Arnold render, but this works just fine.,

I don’t need alembic or USD or anything.,

Here are the first 50 frames because it is a bit large.

I have tried using apps to stitch them, because I read that it needs to be imported as a single abc file, but I haven’t found a way that works.

I tried exporting as USD, which I can’t get to work with Arnold Procedural…

There is a new free beta fluid sim app called Storm HydroFX, which has realtime fluid sims you can export only as alembic.

I tried to cache the files and import into C4D 2026, however, the image sequence does not import as one, but rather it only imports the first file I select.

So, I only get the thinking particles for the first frame, and if I…

I am trying to get this logo to stick to the character geometry.

It is a mixamo character with a skin tag on the geometry.

When I use the surface deformer, it floats about an inch or more above the actual surface, with no way to adjust it in the deformer settings.

I used the shrink wrap deformer to achieve this in the photo.

It is not perfect, as the…

Does anyone have a way that works?
Just take any mixamo character, put a plane object next to the back of them, and try to do a surface deformer.

If yours attaches and moves with the character with NO huge gap between the geometries, I would appreciate sharing the scene or which version you have.

It does not work under any circumstances for…

I understand that, but that can be tricky to lineup with uv coordinates.

I have seen tutorials that have it work perfectly onto cloth objects. The mixamo character is not cloth, but it shouls work the same.

Maybe ill just make it a cloth object with mix animation to pins and see if that works.

I am trying to get an image on a plane object to surface deformer into a jacket of a mixamo character.

It almost works, except there is a perpetual 1 inch gap between the plane and character geometry with no way to offset it closer.

I can’t find any other settings that could help.

Anyone have advice?

Can anyone replicate this with a simple plane…

I have a scene with lots of objects and mixamo characters. The viewport FPS is about 7 when running the scene. Even if I make every single object invisible and disable all animation, the viewport is still just as slow.

What would be causing my viewport playback to be so slow?

No. Setting it to 3D layer doesn’t help, either.

You can see what happens to my cursor when I mouse over the layer.

It can’t be selected.

It is inside a composition that is an AEC file from C4D. So all the other layers are 3D, however, nothing like this happened with the other 5 AEC file compositions I have already used. I just tried the next AEC…

I have been making precomps no problem. Now suddenly, I try to precomp just another layer like always, and the precomp then becomes invisible and unselectable.

What is going on? I have never seen this.

Ok, what I just realized is that even though it might still be a weird bug, the workaround is to put my layer into the timeline and THEN shift drag it beside the layer.

What I was doing was dragging it straight onto the timeline and trying to shift drag it directly beside a layer, which wasn’t working.

I found that if I just put it somewhere beyond…

Thank you for the advice.

I don’t want to install an older version. I might try upgrading if anything.

I will try the tip about sequencing.

When I hold shift on the timeline to move a layer exactly side by side with the layer above or below it, when I zoom in I can see it is always overlapping by 1 frame.

How can I snap the layer so it is exactly side by side without overlapping?

I don’t want to waste time zooming in with so many layers, and I don’t like wasting a single frame.

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

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?

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…

Ok, so I’ve realized that in addition to using the Arnold tag on the particle group–which gives very limited control to what object is emitted in the render and the basic properties–using a Cloner object with the object set to the Particle Group actually does let the emitted objects show up in the viewport and render. Before, I was trying to…

Using a Cloner object with the object set to the Particle Group actually does let the emitted objects show up in the viewport and render. Before, I was trying to set the object as the Emitter itself, which is incorrect.

Creative Cow isn’t letting me respond the way I want. It detects “spam”

I am actually using Arnold to render, and I’ve found that i need to apply an arnold tag to the particle group itself rather than the emitter object to get it to render anything.

I’m wondering now if I need to either set the Cloner Object to apply to the particle group as well, or maybe I’ll try arnold scatter on the particle group.

I am trying to…

I am trying to emit particles from a mesh emitter surface from an object and have other objects be the emitted particles in the render.

I know I could always do this with the legacy emitter and a cloner, but I cannot do it with the mesh emitter. I tried using a matrix object first and then cloning onto the matrix, but nothing I do seems to render…

My project is in meters.

I didn’t realize distance made that much difference.

I had a scene in space where the Earth was at the centre and distance was far to make it appear correct size.

C4D should give a warning like it does for low pyro resolution or high poly count for sims.

I finally figured out why all my simulations were breaking.

My objects were about 10 km from the origin point of my scene.

Apparently, the simulations completely fall apart if the objects are far away from the origin.

I now have no issues.

I have a very simple rope simulation with not that many points in the spline or polygons in the mesh with a sweep.

I have a single point weighted to 100% vertex map for the tearing map, and I set the tear past % to 102 so it actually tears. The only issue is that the simulation completely breaks and crashes C4D.

The timeline freezes on the tear,…

Thanks. I’ll see if I can figure it out.

Also, as far as I know, there is no way to use a vertex map to control where emission occurs. Only polygon or point selection tags can be added to the emission restriction.

I am trying to get the Mesh Emitter to emit from literally anything except the center of the object axis.

It doesn’t emit from surface, points, even when the polygon count is high.
Every particle just emits from the exact center of the object regardless if it is a 3D cube or a plane object.

Is this a bug or does anyone else have this?
I have…

unbelievable. Now suddenly, uniform works but not adaptive.

I literally changed nothing.

I wonder if a new version of C4D fixes this.

Linear — > Adaptive also works, but any setting with Uniform doesn’t work, even though it worked with your scene file.

NEW EDIT:
Ok, you won’t believe this, but by changing the point distribution on my spline in my scene–which was already set to uniform after I made the spline editable–to ADAPTIVE, the entire simulation now works perfectly.

I think maybe the default distribution just needs to be changed for some reason to get it all to work.

BIZZARRE.

I moved the connector tag from the spline to the cube and now it moves around and is connected. However, the rope now doesn’t bend as all. It’s just a completely stiff rope that moves around ‘correctly’ but doesn’t bend or curve at all like a rope would. The rope just changes length completely dependently on how far the cube is from the other…

I will try again, but I have already tried every tutorial I could find and they all don’t work for me.

I tried the balloon on the string, the hanging animal skull, and nothing works using any possible simulation combination with the rope.

I opened your file and it doesn’t work. The object just falls down not attached to the rope at all.

What version of C4D do you have?

EDIT:
Oh, I can see your version in the video.

I opened your file in C4D 2024.5.0 and it works perfectly as in your video.

That confirms it. Maxon broke the simulation system in 2025.

Figures.

Thanks for your help.

I am using c4d 2025.0.2. I don’t know if they broke this whole system recently.

Can you confirm if that tutorial works, and if so, share a file?

I tried that tutorial exactly and it doesn’t work.

Are you able to replicate it?

What i am looking for is a way to have the entire rope able to be pulled along by one end (the other end is anchored in some way) so it is art driven but also retains the rope dynamics simulation. A deformer would be very limiting.

There must be a way to get it to retain its length?

I could rig the rope with bones and use IK to move it along like…

This allows me to move the end of the rope…

That video is interesting. I wasn’t trying to use geometry glue, though, but just the connector object to break voronoi fracture using dynamics.
