We will start implementing Corona into C4D soon. If you would like to help, we would appreciate if you know about some good pages with C4D resources - example scenes, tutorials, reference guides, or ideally, some references for programmers - sample plugin implementations, development discussions. I don’t also know how open are C4D devs to plugin developers - do you know if there is some option to get our specific API questions answered?
Very good new.
some useful sites I know, I hope this can help.
This looks interesting: http://www.plugincafe.com/forum/default.asp

This is excellent news! Thanks a lot, Keymaster !!! 
very cool
good news. thanks for interest cinema4d users.
fine! I’m just glad I will buy your product.
Very good news! God bless you guys, you, probably even could not imagine how great is to give people hope! Your choice is brilliant! Good luck!
I never liked the Mental Ray 
Previously I worked in 3D max and even there used Vray, because I was not satisfied with either the quality and speed of Mental Ray. There are too many options, but at the rate they have virtually no effect.
And after they bought Nvidia, they are very poorly developed.
Really glad this is going to happen. The option for C4D users right now is native engine or Vray. With Corona’s speed it should be really nice.
I tried the demo of Mental Ray for C4D and found it was terrible. Calculating the light for a simple room took forever.
There is MAXON Plugin Developer Conference every year, this year in June 13th, Cologne, Germany. More info here:
It is free of charge and covers plugin development, new CINEMA 4D development and discussion with other developers. Usually you have to sign NDA as some information may not be published to general public. Hosted by Bernd Lutz, MAXON product manager. If you want to apply, please write email to Bernd to b_lutz maxon net (you can CC me to szkandera at digitalmedia(dot)cz so it does not get lost as Bernd is quite busy person)
Keep my fingers crossed,
Standa
EDIT: corrected date of the developer conference, it takes place in June 13th, not July 13th
Well in fact there is also Renderman-compliant engines, Maxwell Render, Octane Render, Fry-something, Thea Render, …
But it’s true C4D users mostly use native renderer or Vray. Most are looking for speed, and Corona could be well perceived.
For plugin programming, the official place to go is http://www.plugincafe.com/forum/default.asp
But there is also http://c4dprogramming.wordpress.com/ that is quite new and maintained by MAXON devs (amongst them is C4D-Jack, a former C4D plugin developer, and a very open guy). I think you could have quite some help from there.
In anyway, glad to see the C4D plugin being developed!
WOOOHHHOOO! This is awesome news!
That’s great news!!
I use Maxwell with C4D, but desperately need something faster
Could You tell me, when approximately can we try the first alpha of Corona-C4D renderer?
i would say it is certain it wont be usable in production for at least a year
Will plugin support cinema r13 or r14 only?
Great great news!!! thanks
The poll you made also showed results that Cinema4D is the most used software after 3ds, so this should be a good move
This is great news! Vray for C4D is at the moment the fastest render engine in C4D, but its development process is super slow.
And it does not support deform motion blur & object motion blur (well.. object motion blur works - some how, but it has lots of bugs or what they say: “features”.
I really want to see Corona for C4D with object, camera & deform motion blur features, at least it should be possible
to create full motion blur support because Mental ray for C4D already has it (but it is slow rendering engine), and Vray will add it to the next version (but, i guess we will see it after couple of years :).
Interesting.
Are there any news on development? Alpha builds?
Or just a thought of it still?
Nice teaser though.
