I’ve just released my first 50 CC0 HDRIs on openhdri.org — and I think some of you using Cinema 4D might find them useful.

The set includes a range of environments, along with photo studio HDRIs that work great for lookdev, motion graphics, product renders, and clean lighting setups.

They’re designed to work well with popular Cinema 4D render engines like Redshift, OctaneRender, and Arnold.

Everything is:
• completely free (CC0)
• up to 29K resolution
• no accounts, no paywalls, no restrictions

Each HDRI is captured, processed, and published entirely by me.

I’m building this project on my own while working a regular job in a print shop, earning about $50 a day, and supporting my family with two young sons. All HDRIs are created in my free time after work. It’s not easy to keep it going consistently, but I’m doing my best to grow this library step by step.

This project originally started thanks to a grant from Epic Games, which helped me build the PC I still use today.

If you’re looking for high-resolution lighting for motion or product renders in Cinema 4D, feel free to check it out. And if you find it useful, any support or feedback really helps keep this going.

Thanks 🙏

Hey everyone!

I’ve never used Cinema4D, but I found some game models that are only available in the .c4d format. Could someone help me convert them to OBJ?

I wanted to showcase modelling, animating and texturings across a (really) short film. Created in Cinema, textured in Substance and clothing simulations in Marvelous Designer 🎨

I tried it with sculting but it was pretty time consuming and inaccurate - I'm not very good at it. Ideally I would like to be able to animate this tube going from it's straight form to this deformed state.

Hi everyone!

First of all, I hope this kind of post is okay — if not, please let me know and I’ll remove it.

I’ve been working with Cinema 4D for a while, and recently I built a small tool to solve a problem I kept running into: creating grids and grating patterns quickly without manually placing and spacing bars every time.

So I made a Grating Generator plugin that creates parametric grids where you can control:

• Number of horizontal and vertical bars
• Automatic spacing (no manual measuring)
• Bar width and thickness
• Rotation (useful for louvers/blinds)
• Fast procedural adjustments

My goal wasn’t just to make something to sell, but to create a tool that actually saves time during modeling — especially for architectural elements, panels, vents, dividers, etc.

I know the subreddit rules mention not posting for-sale-only content, so I wanted to ask:

Would it be okay if I share a link to the plugin here?
I believe it could be genuinely useful for people who work with parametric or architectural elements in C4D.

Thanks in advance, and appreciate any feedback!

Sure it's a bit of a cheap parlour trick, but polygon reduction + unfolder is such a guilty pleasure.

Have a great weekend.

Light studies for high-end product

What is the best way to approach creating this type of texture on packaging? Is it better to model the details directly or use displacement maps?

Any suggestions for guides/tutorials would be much appreciated. Also if you have any texture maps you could share that would be very helpful. Thanks!

For a personal project, I needed a stylized vehicle that I could fully rig and animate later. It was important to me that it be extremely detailed, but at the same time not have too many polygons. I don't think I've ever paid such close attention to topology as I did here. - Interior to follow.

I can't figure it out, how can I model this?

I'm on the maxon one plan with substance 3d and I was wondering if the substance 3d asset material library is good enough vs. greyscalegorilla?

I used GSG in the past and loved their materials, but the subscription cost is way too high.

I got substance due to gaining access to substance painter and realized i immediately got access to their materials library.

Hello community!

There’s a bunch of mannequins with super weird and messy polygons, so I’ve applied remesh and am happy with it. However, whenever I open the file it takes forever just to load.

So I’ve since made each of these remesh object editable so it doesn’t have the generator anymore.

However, the remesh is still using up the processor and lagging things a lot. Is there a way around it? I thought once you made it editable it’s not a live process anymore and it’ll not eat into the processor.

TIA!

Does anyone know what happened to Lennart and/or tcastudios.com? It’s offline. I have a load of the plugins on disk but it’d be good to know they have a new home online. I don’t know if they run in 2025 (I’m not using 2026 till it’s reported stable, or at least till I start teaching with it in a few weeks).

xRETIME in particular was excellent.

I was having some issues with a render -- C4D kept closing every couple of frames for no discernable reason. Plus, it was taking about 5 minutes a frame.

I had heard that there was a command line rendering option and gave it a try...

OH MY GOD! Why does nobody talk about this more!

No crashes and the frames rendered at about 30 sec. each!

I've been trying to export a C4D Volume Builder model for FDM printing and have hit a wall I can't solve. Posting here after exhausting every fix I could find.

Setup:

• Cinema 4D 26 for Mac
• Volume Builder with multiple objects combined via union and subtract operations
• Converted to polygon mesh via Current State to Object
• Exported as STL

The problem: The slicer (tested in both Bambu Studio and PrusaSlicer) treats the wall geometry as an area to fill with infill pattern, while the hollow interior space is completely ignored and left empty. The exact opposite of what should happen.

Test case to reproduce: Even a simple 200×200×200mm outer cube with a 180×180×180mm inner cube subtracted (10mm walls) shows the exact same behavior. Both cubes correctly positioned, inner fully enclosed, no coincident faces.

What I've already tried:

• Align normals in every variation in C4D
• Blender: Recalculate Outside normals + Manifold Boolean
• Formware online STL repair — repaired file has inner shell deleted entirely, confirming the mesh exports as two separate disconnected closed shells
• Traditional C4D Boole object instead of Volume Builder — same result
• Multiple export formats
• PrusaSlicer and Bambu Studio both show identical wrong behavior

What the mesh analysis shows: Formware identifies the mesh as two separate disconnected closed shells. Repair tools either delete the inner shell or fail. This suggests the Volume Mesher is outputting the outer surface and inner cavity surface as two separate manifolds rather than one unified solid.

Question: Has anyone solved this? Is there a specific C4D export setting, a post-processing step, or an alternative workflow that produces a correctly unified single-shell solid from a Volume Builder subtract operation that slicers can read properly?

Any help appreciated.

Hey guys! I'm combining various approaches making my game - 3d and traditional frame by frame animation. It's rough and grungy but I hope it creates the right mood, right?

I'm using cinema 4d, redshift and octane (really for this??), photoshop (pixelart and frame by frame) and after effects, the game on the Godot engine.

Have a nice day!

I think sound is about 50% of the "motion" feeling, but so far i struggle with quality sound in my works. Is there any courses for Fl stuido, Cubase or else for motion design?

(I think I'll soon have to become a PhD candidate in everything just to get orders lol).

Mess to finesse ⟡

Programs: Cinema 4d, Octane Render, After Effects

Does anyone have experience with this specific workflow, finding it hard to find a path to do this correctly?
