Frequenty Asked Questions

Here is a short list of frequently asked questions. You can find the full list at our helpdesk portal.

Hardware & Software FAQ

What are the hardware requirements of Corona Renderer?
Every installer of Corona Renderer contains two versions: standard and legacy.
  • The standard version uses the SSE4.1 instruction set to achieve maximum speed on modern CPUs (Intel i3/i5/i7/newer Core 2, and AMD Bulldozer architecture and newer).
  • The legacy version should run on all CPUs of the last decade but it is about 20% slower
The installer will automatically determine the correct version for you. If you are not sure if your hardware will be compatible with the faster standard version, you can download our demo. The demo installer will tell you which version is supported during the process of installation.
What are the software requirements of Corona Renderer?
  • 3ds Max version: Autodesk 3ds Max x64 version 2012-2018, Microsoft Windows (7, 8, 8.1 or newer).
  • Cinema 4D version: Maxon Cinema 4D R14, R15 or R16, Microsoft Windows (7, 8, 8.1 or newer).
  • Standalone: Microsoft Windows (7, 8, 8.1 or newer).
  • Corona Distributed rendering (available in 3ds Max only) requires Backburner on render nodes.
  • Corona is x64-compatible only.
Which operating systems are supported?
  • Currently Microsoft Windows only. Version 7, 8, 8.1 or newer.
  • Corona is x64-compatible only.
  • Versions for Linux and Mac OS are planned.
Which host applications are supported?
3ds Max is the only fully supported host application at the moment. There are Cinema 4D, Maya, and Blender versions in various stages of development.
Which 3ds Max versions are supported by Corona Renderer?
Corona Renderer currently supports x64 versions of 3ds Max 2012 – 2018. There are no plans of supporting older versions of 3ds Max.

The Render Engine FAQ

Is it CPU, GPU or hybrid?
Corona Renderer is proudly CPU based. It uses Intel Embree Ray Tracing Kernels, the fastest CPU ray tracing solution on the market.
Why is there no GPU version?
Short version: the GPUs are not as great for ray tracing as the marketing sometimes portrays them. Please see our separate article for a more elaborate answer.
Is Corona Renderer Biased or Unbiased?
We say that Corona Renderer is (un)biased. It offers both unbiased and biased rendering solutions. By default it uses a slightly biased solution that merges the best of both worlds: visually plausible results with great render times and without visual artefacts.
What are the features of Corona Renderer?
Please check our feature list.
Are there some converters for materials, lights, proxies?
In the 3ds Max version you can use the Corona Materials/Lights Converter by Martin Geupel which is a part of the installation package. There is also VRay Proxy to Corona Proxy Converter by Pavel Vojacek.
Is corona faster than other renderers?
We believe Corona is fast for what it offers. We try to stay away from any speed comparisons with competition, because it is far too easy to create benchmarks favoring any renderer, regardless of its true performance. Because determining the overall speed of a renderer is a complex topic, the best solution is to download the demo and test it for yourself.
Does it support network/distributed rendering?
Yes, it does. You can do network rendering using Autodesk Backburner, Thinkbox Deadline, or Corona's own integrated solution (requires installed Backburner).

Licensing FAQ

What is the FairSaaS version of Corona Renderer?
FairSaaS or Fair Software As A Service is one of the license types of Corona Renderer. It is paid on a monthly basis (with an option of paying yearly) – it is like paying a phone bill. We have created this licensing model as an answer to the traditional box model shortcomings. It has many benefits, such as affordable price, zero upfront investment, easy scalability, and ability to install the latest updates as soon as they are developed. There are more details in the Prices and Licensing section.
Can I use my FairSaaS License on multiple computers?
Yes. But only one computer can use the license in workstation mode at a time.
Do I have to be always connected to the internet to use the FairSaaS license?
It is advised to be connected to the internet, so Corona Renderer can check its license validity. But if the internet connection is not available, you can still use it for a few days.
Will I be able to render if my internet connection is lost?
Yes. Corona Render checks license validity every time you start your application. But if the internet connection is lost for some reason, it will work normally for a few days.
Do you offer a student license?
Yes, we do. And students can use it for commercial projects as well. Read more about it in our Prices and Licensing section.
Can I resell my Box license?
Yes you can, but please notify us first, so we can update our records, thanks. If you are buying a license, do not trust unknown people selling licenses over internet. Please contact us first to verify the seller. Some scammers are buying licenses with stolen credit cards and reselling them. Those licenses will get blocked.
Are there some free render nodes bundled with the license?
Yes, each workstation license comes with a couple of free nodes: 3 for each box license, and 3, 5, or 10 for each SaaS license. Note that the workstation license can be used also as a render node if needed.
What about cross-grade?
No problem with that. If you were using 3ds Max version and you decide to migrate to Cinema 4D, Maya or any other version which will be there, you can do it for free. But should there be some price difference between the versions (which we are not planning at the moment) you will have to pay the difference.
Network license server? Network licensing?
Yes. We have a network license server which works with the floating FairSaaS license (no server is necessary for the node-locked box licenses). A network license server has to be connected to the internet and must be on the same local network as the nodes it is servicing.
What if our servers are unavailable?
As above, no big deal. Box versions does not need them and FairSaaS version will start and let you work for a couple of days without connection.
Is there a demo/free version?
Yes, there are several options to try out Corona:
  1. Alpha v6 for 3ds Max is free forever. It does not have any time lock and it is a production-proven build. It is freely available without watermarks, resolution limitation, or any other limitations. The only problem is that it is no longer maintained, so no bug fixes will be available.
  2. 45-day unlimited demo. of the current full version. It is freely available here.
How is it with the bug fixes if I do not have subscription?
If we find a bug, we will fix it if you have subscription or not. You will always get your bug fix for free, the subscription gives you also feature updates.
How long until I get a license after I pay?
Few seconds. Immediately after the payment you will get multiple emails with your invoice, discounts, and serial numbers/login that you can immediately use to activate Corona.
Are the monthly/yearly licenses valid for 30/365 days or until the end of the month/year?
All monthly licenses are valid for 1 month, not only until the end of the month. Same for the yearly licenses: they are valid for 365 days from the purchase date.
