I take a few classes at FXPHD and one question I had today was about using the Cinema4D Atom Array and how to have individual control over the spheres.
I rebuilt the Atom Array using a couple of Cloner Objects. The first Cloner adds a Sphere to each Vertex of the object I’m cloning onto. The second Cloner Object adds a Cylinder to each edge of the object I’m cloning onto. The trick here is to use the Edge Scale parameter in the Cloner Object. This allows you to scale the clones to fit the length of the edge. You can also offset the clones for some interesting effect.
Cloner Edge Scale
To control the spheres, you can of course use Effectors, and this combined with the MoGraph Selections allows ultimate control. Alternatively, you can always use Xpresso for even more flexibility. The Atom Array is a simple one trick pony, this type of setup not only replicates the Atom Array but gives you a lot more besides.
Scale along the edges of the mesh
I also added the MoGraph Color Shader inside a Colorizer, this combined with a Random Effector allows you to randomise the colour of the Clones, but keep the random selection within a specific range of colours.
The scene is free to download here. I hope some of you find this useful?
I found this Pyrocluster preset kicking about in my 3D library today and I cannot remember where I got it from. If you sent this to me, then please let me know and I’ll credit you in this post.
Pyrocluster with Thinking Particles
I’ve used pyrocluster many times and although I feel that there is much room for improvement, it is still a unique tool within the Cinema4D feature set. If you haven’t ever used this volumetric shader system then this short tutorial should get you started.
Pyrocluster Volume Tracer
In this tutorial take you through the steps to create a simple cloud fly through. Pyrocluster has got a bit of bad rap over the years for being painfully slow. This tutorial demonstrates some simple tricks to speed up workflow and ensure you are not waiting around for renders when setting up these type of complex volumetric effects.
Pyrocluster Preview
The setup is fairly basic but there is a lot of scope to take this type of technique much further and create some cool effects. I’d definitely encourage you to play around with the lighting, use falloff, add shadows. Check the lights ‘Project’ tab where you can choose to use specific lights for Pyrocluster Illumination and Shadow Casting. Of course there are so many things you can do with MoGraph and generating Thinking Particles, shading those particles with Pyrocluster opens up a whole new world of rendering.
In this tutorial, Tim Clapham takes you through the process of building a controller for a deformer object. In this example we take a null object and then use the position values to drive the strength of a bend deformer with a basic Xpresso setup.
Bend Controller
Once this simple example is complete, the setup is enhanced by calculating the angle between the source object and the controller which is then used to drive the angle parameter in the bend deformer, thus the deformer always bends towards the controller.
Xpresso Setup
This type of setup has many uses particularly for animation and the setup can easily be expanded upon to allow control of several deformers directly in the editor viewport. As an example, Tim takes the setup one stage further by adding the MoGraph Delay Effector into the equation. This allows you to add a spring effect or a nice ease into the deformer strength.

Here’s a new tutorial for all you Cinema4D users out there. Hopefully some tips and tricks that will help improve your workflow.
Attribute Manager Project
The humble Attribute Manager is one element of the C4D user interface that we use constantly and it has many features that may or may not be known to you. In this tutorial I attempt to cover as many of them that I can remember. I improvised when recording this, so please excuse any fumbling or mistakes (I’m not so good with my alphabet!).
Attribute Manager Modes
I’m sure a lot of the stuff I mention you will know already but I’m guessing that there will be at least one or two new tips hidden amongst these. I do not go through all the features of the AM, there is after all so much you can do there. However I think it would be a great idea if you add your own AM tips into the comments then everyone who visits this page can glean some extra knowledge along the way.
Attribute Manager History
Anyway enough of my banter, check out the tutorial below, or head over to Vimeo to watch.
In this collection of tutorials created for Maxon’s You Tube channel, I explore techniques you can use when working with Cinema4D Multipass rendering in combination with the After Effects exchange feature of Cinema4D.
C4D To AE Basic
Taking you step by step through the process, the tutorial starts by covering the basic principles of working with multipass rendering and exporting 3D information from your Cinema4D scene over to your After Effects projects. Ensuring you use the correct colour management for outputting from Cinema4D and configuring your After Effects projects to make sure the files are composited in the right environment.
C4D To AE Advanced
The second tutorial then moves on to some more advanced techniques including the use of Xpresso to export 3D information from specific clones and outputting lights as separate render passes. This information is then imported into After Effects and the 3D data used in combination with third party effects such as Trapcode Particular and Video Copilot Optical Flares.
AE To C4D - Camera Tracker
Finally I take you through the process of transferring your After Effects information over to Cinema4D. Using The Foundry Camera Tracker, you will track and solve some footage, resulting in an After Effects camera and reference nulls being created. This camera and null information will be exported from After Effects into Cinema4D and used to build some basic proxy geometry for catching shadows and reflecting the environment. This is then output using Cinema4D multipass rendering and composited back over the original footage in After Effects.
AE To C4D - Camera Mapping
The powerful multipass rendering and compositing exchange features of Cinema4D allow you to access the individual render passes such as reflections, shadows and lighting from your 3D scene directly in your After Effects compositions, allowing you to grade and enhance your renders with ultimate control. Access to 3D data taken directly from your Cinema4D scene and imported into After Effects ensures precise fidelity between native After Effects 3D elements and rendered elements from your Cinema4D scene.
C4D To AE - Light Passes
As well as discussing the exchange feature in-depth, I’ll demonstrate many useful techniques for working in Cinema4D and After Effects, including scene management, basic lighting, MoGraph Color shader, MoGraph Multishader, Cloner Object, Effectors, Rigid Body Dynamics and much more.

Oh, I think I forgot to mention that all of this is free, thanks to the awesome team at Maxon. The iPod model is something I made specifically for this tutorial, it isn’t the greatest example of modelling, however it is native C4d with lowpoly mesh, hyperNURBS and other generators, it has a UV map and best of all it’s free for use in any of your projects, commercial or otherwise. It would be nice if you do use the model in any renders or on your site if you could please link back to helloluxx. The model is not free to distribute in any form and I’d appreciate it if you sent people to this page instead, thanks.
C4D To AE Basic: Part 1 (~25mins)
In the first part of the tutorial Tim shows you how to install the Cinema4DAE plugin into After Effects. Walks you through the setup for the free iPod model. In Cinema4D, you will animate the iPod model and a scene camera, manipulate the animation curves in the F-Curve manager. Create some basic materials and use the Layer Browser for organising the scene.
C4D To AE Basic: Part 2 (~32mins)
Setting up some simple lighting for the scene. Optimising the render settings for speedy preview rendering. Working with multipass rendering and using colour management combined with Linear Workflow when outputting your renders. Using the compositing tag to isolate reflections to specific objects and assign object buffers. Flight check the render settings in the Picture Viewer to ensure there are no mistakes before committing to the high quality render. External Compositing tag and AEC export for transferring 3D information from Cinema4D to After Effects.
C4D To AE Basic: Part 3 (~20mins)
Importing the AEC file into After Effects. Correct colour management settings for working with Linear Workflow and multipass compositing. Screen replacement on the iPod model. Colour correction opportunities. Compositing the rendered shadow and reflection over After Effects layers.
C4D To AE Advanced: Part 1 (~30mins)
Setting up a Cloner Object to create a flow of hundreds of objects along a spline. Using the MoGraph Multishader and the MoGraph Color Shader to create multiple coloured versions of your clones with corresponding coloured screen graphics. Adding variation to the animation with the Random Effector.
C4D To AE Advanced: Part 2 (~17mins)
Animating a camera using nested null objects. Basic lighting. Configuring multipass render settings to output various light passes.
C4D To AE Advanced: Part 3 (~24mins)
Using Xpresso and User Data to determine the index value of clones and then linking objects to the position of these specific clones. Baking object animation using the Bake Objects function. Exporting and then analysing the AEC exchange file.
C4D To AE Advanced: Part 4 (~30mins)
Importing the multipass renders and 3D information from Cinema4D into After Effects. Using the imported lights with Trapcode Particular and VideoCopilot Optical Flares. Adding After Effects 3D solids and effects to match the Cinema4D imported camera. Returning to Cinema4D to explore a technique for isolating mattes from individual objects within a Cloner Object.
AE To C4d: Part 1 (~18mins)
Using The Foundry Camera Tracker to track some footage in After Effects. Set up a ground plane and reference nulls. Export the 3D information to Cinema4D.
AE To C4d: Part 2 (~28 mins)
Create some proxy geometry in Cinema4D for catching shadows and reflecting onto objects using the reference nulls and solids exported from After Effects. Add a dynamic particle system of spheres which interact with the proxy geometry. Output multipass renders and return to After Effects to composite the render over the original footage.
Align to spline is no doubt an expression that most Cinema4D artists will have used at some time or another. The problem with the built in expression is that it is clamped and you can only animate the position parameter from 0% to 100%. If you want the object to loop or wrap around the spline it is not so simple.
Align To Spline Xpresso
There are other solutions available within the application, you could use MoGraph and clone onto a spline. Then use the offset parameter. However in this tutorial, I show you how to build a loopable align to spline expression using just Xpresso. The advantage here is you can use this setup with the most basic install of Cinema4D and also the object is still in it’s original state as it hasn’t been passed through a generator.
Align To Spline User Data
I show you how to include a tangential option and the addition of a pop-up menu to define the axis you would like to align.
Anyway enough of my waffle. Check out the tutorial below or click through and watch it over on the helloluxx channel on Vimeo

Here is a quick post to share a piece of python code that I use in nearly every C4D scene these days. It is really simple and all it does is take the current state of the objects “Visible in Editor” parameter and apply it to the same objects “Visible in Render” parameter.
I use this to hide objects that I don’t want to render. You can of course simply keyframe both parameters, but this means you only need to key the Visible in Editor parameter. Another option is to use a Display tag which will also allow you to keyframe the object visibility. So it is nothing revolutionary that I’m offering (sorry about that
The reason I use this is simply because you have a visual indicator in the Object Manager of the current state of an objects visibility, you don’t get this with the Display Tag unfortunately. Would be kinda cool if the eyeball closed to indicate visibility, similar to PS layer switches.
Anyway here’s the code, simply copy and paste this into a Python Tag and then choose File > Save Tag Preset in the Object Manager. The tag will be there for you every time you need it.
Start copying here…
import c4d
#Welcome to the world of Python
def main():
# get object tag is attached to
obj = op.GetObject()
# get visibility from editor
visibility = obj[c4d.ID_BASEOBJECT_VISIBILITY_EDITOR]
# pass editor visibility to renderer visibility
obj[c4d.ID_BASEOBJECT_VISIBILITY_RENDER] = visibility
…Stop copying here
Thanks to Patrick Goski who actually wrote this little snippet of code.
By the way if you get errors when you copy and paste this, it may be because of the formatting, so make sure you don’t use tabs and that it looks like this..
I recently completed a tutorial for the Maxon’s You Tube channel. It goes into quite a bit of detail, so for that reason it is split into 4 parts.
Something you might be interested in?
I’ve copied some of the blurb from the You Tube page here so you get an idea of what I cover in the tutorial. If you want to check it out then please visit the Maxon You Tube channel.
In this tutorial, Tim Clapham from Luxx takes you step by step through the process of creating a Motion Graphics animation with CINEMA 4D.
You will learn how to use MoGraph elements such as the Cloner Object and how various effectors can be used to control the generated clones.
Working with Release 13, Tim covers several of the newer features such as the XRef object and the new Physical Renderer. However, throughout the process, options are presented to enable users of versions prior to Release 13 to complete the tutorial.
You can view the first section here, but why not visit Maxon’s channel and you can watch the other sections and also check out some other great videos.
Here’s another little tip for working with Cinema4D, specifically Thinking Particles. I offer up a solution to what appears to be quite a common problem with TP and hopefully this small tutorial will stop a lot of head scratching.
This time around, I show you a simple technique you can use to stop the pulsing you sometimes see with Thinking Particles when your emitter is moving too fast and you get those big lumps of particles emitted on every frame rather than a nice smooth emission.. Yes – you guessed it, this is sub-frame particle emission.
Of course this tutorial doesn’t cover many of the different ways that you can emit particles using TP but hopefully it gives you some idea of a solution that you can adapt to your own TP scenes.
If you ever wanted to work with high and low resolution models in Cinema4D then this tip should come in handy.
Using the Instance Object combined with a simple Xpresso setup, this shows you how to create an object that allows you to work with a low polygon model and then swap this out for a high polygon version whenever you need to render or preview the final result.
This technique will keep your workflow streamlined, and allow you to perform tasks such as dynamics simulation and caching without the overhead of polygon heavy scenes. Once the caching is complete, you can switch out the object for the detailed version and render away.
Once created, this simple object will become a vital part of your Cinema4D library. You’ll never know how you worked without it!
Kudos to Kai Pederson who originally showed me this trick.
