If you can't see the Cycles 4D Menu within Cinema 4D, check the Cinema 4D Console and if Cycles 4D isn't showing in the Console either, you will need to install some redistributable files from the following link:
From there, please download and install the 2015-2019 x64 Visual C++ file (vc_redist.x64.exe).
If Cycles 4D is showing in the Console, but not the Menu then contact Technical Support.
If you have installed X-Particles on a Windows system but it is not loading, check the Cinema 4D Console (Shift + F10) to see if there are any relevant entries. If the Console shows an entry for the INSYDIUM Bridge (see below), this means that your system is missing the necessary Microsoft Visual Studio redistributable files.
To fix this, please visit the following link:
From there, please download and install the 2015-2019 x64 Visual C++ file (vc_redist.x64.exe) and the 2013 Visual C++ file (Microsoft Visual C++ Redistributable Packages for Visual Studio 2013).
If you do not see INSYDIUM Bridge in the console, or installing the above files does not resolve the issue, contact Technical Support.
I highly recommend anyone using X-Particles to use it in tandem with Cycles 4D. The bridge between the two allows for some amazing effects and control over the appearance of your particle systems. Being a regular Cinema 4D user also meant that Cycles 4D was fairly easy to pick up and integrate into our workflow. - Matthew Encina Blind.com
Cycles 4d is the render engine I’ve always wanted to have as a C4D artist. It’s a feature rich engine that doesn’t ask you to change the way you work to get the render you want. You can render entirely procedurally, or with image textures. It doesn’t feel like a plug-in at all, it feels like an update. - Casey Hupke
I find this is the absolute go-to anytime that I want to do anything with particles… There are so many possibilities and great looks you can achieve with even just some really simple setups - Mike “Beeple” Winkelman
Playing with TP and Xpresso is a thing of the past for me now. - Ash Thorp
Territory use X-Particles a lot when it comes to detailed simulations for feature film UI. The ease of use means we can turn work around quickly without sacrificing a demanding quality bar - David Sheldon-Hicks / Founder and creative director / Territory Studio
Designer-friendly and technically advanced, simply powerful and art direction-able, X-Particles is an integral tool of my workflow, always impressed how Insydium are constantly developing and refining the most important toolset for Cinema 4D. - Motion Designer; Director; Brett Morris
X-Particles is an essential tool in my creative workflow - whether it be for creating daily images or commercial client projects. It allows me to quickly and intuitively throw together visual concepts or drill down into more complex, technical setups. The integrated interactive and video manual are outstanding, and if you can’t get the answers there, the support team are personal and very quick to help out. - Joey Camacho, Raw & Rendered
