@Dr-Sassi Happy holidays to you too.

Of course.
I have some node experience from Houdini, Substance designer and Fusion. But I also have a lot of coding experience, which come in handy when working with nodes.
I usually just find some basic tutorials like the one discussed here to learn the basic principles of the system. After/along with that understanding the datatypes that is send through and how to get the data from them i find important. Once I get that overall understanding I start to dive into the different nodes. The general idea with the different node systems are somewhat the same. But they always have some special ideas and tricks to make things easier for the user. It takes a bit of time to figure all that out by reading the manual, so any tutorials are very welcome. Maybe I'll do a few my self once I got it figured out.

@Dr-Sassi Thank you, that helped. I've been holding out for a couple of years, as you said things have been changing often. But I thought now was a good time to get into it. I really think it will add a ton of value to my workflow, so I'm exited to learn more.

I got it working now. Posting this solution for others who may find it. For the top Get Element I set Index to 0, for the other I set Index to 1.

Hi

I'm trying to complete this tutorial: https://youtu.be/F82AuduoN_g?si=FCvTrKewkTWlv5Yx&t=165
But at 2:46 when he adds a nested port to the Obejct Group Input, I can't replicate it in C4D 2025. How do I create a nested port in this version?

Thanks,
Jakob

@Dr-Sassi Thank you. Yes, that'll work.

Hi

I have a super simple test setup. I have a linear cloner and an effector with a linear falloff. The effector scales the clones up. The cloner have the rigid body tag, so the clones should be dynamic. There are no gravity in the scene.
My plan was that as they scaled up, they would collide with each other, and push each other apart. My actual setup have objects of many different shapes, so I can't simply use the push apart effector.

This must be possible, what am I missing?
test grow and collide.c4d

Thanks,
Jakob Wagner

@Dr-Sassi Thank you. That was it. My renders are now looking as expected. Appreciate it!

@Dr-Sassi It feels like there is a bug somewhere. I tried to rebuild it in another file from scratch. Now it seems to work. Unless I activate motion blur. Then it gives me the errors again. The rings will be blurred but the tube will not. I have enabled deformation blur.

tube_rebuild.c4d

@Dr-Sassi Thank you for looking into this. Did you make any important changes to the render settings too?
It seemed to work at first. But if I change the timing it will once again be misaligend. Also, the error messages are still showing up.
Even if I add a mograph cache tag to the cloner, and it looks right in the viewport, the render will still be off.

Same, with changed timing:
cv4_2024_drs_24_mori_01.c4d
cv4_2024_drs_24_mori_11.c4d

Hi

I have a simple tube setup where a single spline with a bend deformer drives both a sweep and a cloner.
When I render the setup I get a mismatch between the two and redshift gives me these warnings:

WARNING: Object: 'test cloner problem.c4d:tube.Sweep.Cache.Sweep@2' Contains inconsistent topology. Deformation Blur output will be inconsistent.
WARNING: Object: 'test cloner problem.c4d:tube.Sweep.Cache.Sweep@2' Contains inconsistent topology. Disabling Deformation Blur.

Sometimes the mismatch also happens in the viewport. When it does. I can disable/enable the cloner and they will align again. This tells me that it appears to be the cloner which is misaligning, although it is the sweep that the render complains about.

Source file: test cloner problem.c4d

All help will be greatly appreciated
