We are a team of 3 people using Cinema 4D almost exclusively for our CG jobs and we use Octane as much as possible because of its immense speed and faster workflow compared to most other renderers out there.
We switched to version 14 (Studio) very recently and are using Cinema 4D since version 8, so we have a lot of experience with Cinema 4D. (Version 11.5-13 also available for compatibility to others)
We are also beta testers for Octane for a year now and bring quite some experience with us when it comes to using Octane (by far more than a year when including the time where we tested the demo).
For example we also did some changes to the Maya exporter plugin to fit our needs (changes posted in the maya forum), we got really into Octane in the past year and we are loving this awesome renderer. We were waiting for this news post since the 3Ds Max beta was announced. The integrated plugin really means a lot for our workflow and it means that we can finally ditch Vray completely!
If you want to see some of our work you can have a look at our website (not everything is 3D, we also do 2D Motion Graphics), it contains some stuff from the last 10 years up to the present:http://www.mainframefx.com/www/works.html
Specially have a look at the advertisment for "Venta" it was done with Cinema4D and Octane (it's in the bottom right corner of the first page of the gallery, can't direct link it unfortunately)
Edit: Here the more recent version, I just saw the one on the website is from a production state: https://docs.google.com/file/d/0B9VThca ... h5VGs/edit
I will try to find some more recent C4D with Octane footage that is not under some form of NDA and add it to the post tomorrow.
Please note that the reel on the site is very old, a new one is currently in the making and includes quite a lot of products made using Octane
The current one is from the "pre Octane era".
Edit2: Here are two animations not assoicated with any job. Though the bottom one had a successfull pitch, the corvette is a WIP for our new reel. Both were made in Cinema4D and rendered in Octane.
Click to watch (maybe scale the window, gets scaled heavily on big screens):
The car scene is missing some elements like smoke that are difficult to include via passes. With the integrated plugin we could finally render everything together.
We are using Windows 7 SP1 64bit on every PC. Every PC is equipped with atleast one "Geforce GTX 560 Ti 448" with 1280MB of VRAM each, one of those cards is pretty much on the performance level of a GTX570 because of the higher shader amount, so we are well equipped from the hardware side.
We are currently working on a commercial for a very well known US beverage producer using C4D and Octane and it would be a huge help to use the integrated plugin instead of the exporter for this job. We have to animate lights and cameras. With the exporter this is a rather painful job as lights aren't exactly possible to animate with the Octane Standalone so we have to use some unintuitive tricks to achieve animated lights.
If we get to be beta tester we will report every little detail we find, I (Paul) am very active here in the forum and will try to give bug reports on a daily basis and will collect feedback from the others here at the company. We will switch the beta license around the work places so everyone can have a go with it (if we happen to be lucky and get chosen for the beta).
Thank you for your consideration.
