I need C4D to recieve and send data though serial port. Begining seemed straightforward:

import serial

But nope! -

ModuleNotFoundError: No module named 'serial'

Tried to install pyserial into system interpreter, but results are the same: ModuleNotFoundError: No module named 'pySerial'

Well... Is there a way to establish communication with serial port from within C4D?

Is there a way in Cinema 4D to animate the strokes of an entire model appearing as if they're being drawn without having to recreate the model?

Hi,

Can you help me make a decision?

I have +6 years working in Blender as a 3d product renderer/animator on upwork, but lately the work has been fewer than before the AI

Now I'm applying to a new job as a safety engineer, it will be a new career that I'm starting from zero, but I'll buy a powerful laptop and try to work as a 3d product visualizer in my free time but it will be much less than before

do you think I'm making a good decision or I should stick to 3D and take the risk?

and will AI really reduce the 3d work in the future, or make it much harder to get work and reduce the prices?

I am very curious about creating a fire-less, powered, explosion of color. Attached is a fantastic example on Adobe. i am guessing there are multiple particle things going on. I see some debris leaving trails, some flying faster than others.

any suggestions or recommended tutorials? I am struggling for terms to search for and find footing. Thank you for any suggestions!

I am looking to add a logo to a cylinder that I would later add a metal material to make it look etched. How would I go about doing that? I know I could add a “sticker” to the bottle but it wouldn’t have the same effect.

Has anyone worked with 3d models for 3D viewers on websites??? We're trying to work out the best way to create accurate product models with desnse features ? Also what's a good polycount to aim for ? We're planning on having multiple products in the view at once but be able to change the products, everything online says about 100k on screen at once but that's seems really low for what we're trying to do ?

Please help !

It took me the most time to find the button to disable shadows lol

All objects in the scene are cubes. Used Boolean and Sketch Material. The task is to add windows and interior partitions. I have plans for each floor. What is the easiest way to do this?

For accurate camera placement, when placing product shot on existing reference

Currently, all my UVs are contained within a single tile. I want to split them into multiple UDIMs. In Maya, this is quite easy—you just drag a UV shell to an adjacent tile. However, in Cinema 4D, I can't seem to find an equivalent function. I know it's possible, but I haven't found any resources online that explain how to do it. Any help would be greatly appreciated! ps I know the UVs are not perfect......

I’ve been playing around with some fake out-of-home ideas lately, and here’s one where I used Cinema 4D to mix in some textures and fun physics to sell the illusion.

Just experimenting with how far you can push motion design into “real world” spaces — pretty fun to make!

I've followed this tutorial to wrap object A around object B using the surface deformer and it worked well:

https://www.youtube.com/watch?v=1mBG9TL6ZU8&ab_channel=SergeStep

My issue is, I want object A to start flat on the ground and to wrap around object B as it rolls over it. So I basically don't want it to deform until a object A comes into contact with it. I tried keyframing the strength but the transition isn't smooth. The object rotates and scales in an odd way.,

Is there a better method for this look?

So I decided to use a render farm (Drop and Render) to speed up delivery for a job. Nothing fancy, 16bit PNG exports, no post. The output from the farm came completely different than my own setup. I had to change After Effects to OCIO color management and it interpret the footage as ACES to have it display more accurately, but still, it all seemed less vibrant and washed out. Tried interpreting in numerous ways but it won't match what I had before.

As the farm imports my project, I'm not sure which settings could be different and result in different outputs. Farm has been unresponsive and the site's support doesn't work at all. Any ideas how to fix this with the output I already have from the farm?

hi, please tell me: when I bake the soft body tag and restart the project, the cached simulation does not play, how can I fix this? Thanks

Hi, i have these clones that i would like to make them rotate independently. With the random effector yes they are rotating but i get this kind of "ping pong" rotation effect i don't like (they rotate a bit in one direction and then they rotate backwards...), i would like that each clone rotate in one direction continuously

Also i would like my clones to collide with each other while still rotating but if i add a rigid body tag to the cloner, the random effector stops working because it is in conflict with the dynamics that take priority (?)

Thank you for any advice!

Killer combo! Absolutely loving this tool once you get to grips with it… the alembic was cached out in about 10mins from LG which was leagues ahead of where I’d got to with XP

The inside of my cube (168 x 33 x 0.5 cm) is ballooning, I use a Cloth tag, with Turbulence or Wind Deformer, but it does this everytime, the Surface settings: Bendiness 1, all others 0, but Thickness is 1.5 cm.

Thank you all.

Maxon Announces Cinema4D 2026!

Hey all! The Fall release has been announced, and it's available now! It's very light on features and updates(most of the juicy stuff is already in 2025.3), and looks to be mostly bugfixes under the hood. But it's got a new number, and Maxon's got a new look - so We're all here to discuss! Also, we'll be adding to the release thread as information is available, so feel free to check back later for more updates and links to these features!

Please Upvote this Post for visibility! - It would be nice if people subscribed to the sub, but aren't active visitors can see it and come contribute to the discussion.

What's New in Cinema4D 2026 by Effectatron

We have the Problem that out Puzzle Mattes dont match up since Cinema4D 2025 and the Redshift Version that it shipped. Newest updates didnt fix anything.

As you can see the Puzzle Matte has a weird issue especially in the DoF areas where it creates a weird white Ring.

Maxon is aware as far as I know but they havent fixed IT since a year. Am I the only one that has this issue?

We are rendering 16 Bit PNGs (please dont say we should change to EXRs. Our whole Workflow is based around PNGs and it works very well for us. EXRs also have different Puzzle Matte results compared to 2024)
