TOPOWIRE for Cinema 4D
This is a must have plugin for three main reasons: Fist, is one of the coolest plug-ins I've ever played with, it makes it so easy to create something that most of us will have to struggle with at some point: CABLES. Second, Merk is a lovely, young and creative genius that creates the most amazing tools and tutorials, he is always ready to help and will always point you to the most incredible way of making something complex the easy way. And third, I'm his affiliate so if you buy through my link I'll get something back :).
trypogen 1.5 for Cinema 4D
This is another great plug-in from @Merkvilson. Create incredibly complex structures with this generator and make your audience cry!
I'm Merk's Affiliate so if you buy it from this link I'll get a part of the payment but if you prefer you can go through his links.
This is a very handy Cineversity script that I use all the time.
I makes it easy to get rid of extra stuff on the viewport when you want to do a viewport preview render.
CV-splines to objects
I can't live without this one. It saves me so much time if I need to create tubes or any type of spline extrudes.
It also includes four curve "modifiers", witch to of them I use all the time, CV-Chamfer and CV-Outline. Check this simple video I did on how to use them.
Definetly check it out.
I can't believe this tools are not part of C4D. This is how C4D should be with all it's modeling tools.
They should be all live and parametric.
If you didn't already, get them now, they are free and incredibly powerful!
Redshift is an incredible GPU Render Engine available for most 3D Apps. It's the tool I use everyday and I love it! It's fast, flexible and reliable. The Cinema 4D integration is great, the best in my opinion.
Also Redshift's update cycle is incredible fast, almost weekly they add new tools, and their support is as good.
One of the best Render Engines around. You can download the Demo and try it for your self.
Octane is most used unbiased GPU Render Engine by the Motion Graphics community. It's incredible quality and rendering speed makes it one of the best. And also it's $20 monthly subscription makes it very affordable.
It's an amazing tool so don't forget to check it out.
This is the must have particle simulation tool for Cinema 4D. X-Particles is an incredible multi-threaded particle system that let's you simulate Liquids, Smoke and Cloth, also supports VDBs and integrates seamlessly with C4D.
Basically if you want to do cool shit you must have it ;).
