Arion stand-alone v2.4.3 and its DEMO are out!

Arion Standalone v2.4.3 has been released

Dear RandomControl customers,

Arion stand-alone v2.4.3 has been released a few minutes ago.

We have also released a DEMO version of the stand-alone for those of you willing to try it out. Like ArionBench or the RHINO LIVE trial, you can download the DEMO from the Customer Area after logging in.

In the upcoming days we will sort out the changelog and make some adjustments to the website. We will also send out a mailing announcing the availability of Arion v2.4.3 for those of you not following us on Facebook/Twitter or reading this blog often. Right after that we will resume the development of MAX LIVE and will focus on it until MAX LIVE v2.4.3 is ready for release.

Thank you!

Preliminary v2.4.3 changelog

As promised, here’s a preliminary changelog for the Arion core (RCSDK) and Arion stand-alone v2.4.3.

We have shifted through several internal builds in the past weeks, so the changes since the latest public stand-alone are labeled as v2.4.1, v2.4.2, and v2.4.3. In particular, v2.4.1 is where most new features happened (as announced on this very blog in the past months), and v2.4.2/v2.4.3 have brought some critical fixes.

We expect to release the new Arion stand-alone this week as mentioned a few days ago.

Thank you!

Arion stand-alone v2.4.3 is about to be released

Dear customers,

Development of RCSDK v2.4.3 is officially complete.

As of this moment, Arion stand-alone and RHINO LIVE are 100% compatible with the latest version of our core technology, so we expect to release Arion stand-alone v2.4.3 (plus a re-compiled RHINO LIVE and a re-compiled ArionBench) in the upcoming days (next week). Due to the complexities of MAXSDK, MAX LIVE v2.4.3 still requires some deep adjustments, and it will take us some more time to release it.

In the upcoming days we will post a summary of the new features in the v2.4.x Arion core. These features are common to all our products.

Right after the release of Arion stand-alone v2.4.3, we will focus on MAX LIVE v2.4.x until our three products (stand-alone, MAX LIVE, and RHINO LIVE) are levelled and up-to-date with the newest Arion core.

Thank you!

RHINO LIVE v2.4.2 has been released

Dear RHINO LIVE customers and DEMO downloaders,

After the RHINO LIVE v2.4.1 release, we have resumed development of all our product line and the Arion Core, which is now RCSDK v2.4.2.

We have fixed a critical bug/crash in Kepler (sm_30) cards with CUDA 5 that used to affect scenes without any emitters. We have decided to recompile RHINO LIVE with this very important fix and release a new build, which you can download from the Customer Area already.

We will release the corresponding RHINO LIVE v2.4.2 DEMO in the upcoming hours.

This fix in Kepler cards is part of the current version of RCSDK (v2.4.2), so it will be featured in all our products in the upcoming 2.4.x release.


Since RCSDK v2.4.x, our license generation system has changed slightly:

Now each new release of our software requires a new license file

This means that, from now on, when you download a setup for a new release of our software, you must also download and install the license file that matches the version number of the setup.

For example: Right now the Customer Area allows RHINO LIVE customers to download RHINO LIVE v2.4.1 and v2.4.2, plus a license for RHINO LIVE v2.4.1 and one for v2.4.2. The license for v2.4.1 doesn’t work in v2.4.2 and vice-versa.

Thank you!

A little progress update

After the release of RHINO LIVE, ArionBench, and some intensive work on many aspects of our website, we’re resuming the development of Arion stand-alone and MAX LIVE v2.4.x.

As you know from ArionBench and RHINO LIVE, the Arion core (RCSDK) is already v2.4.1. We expect to release a matching v2.4.1 stand-alone and MAX LIVE as soon as we can, and that is what we’re focused on right now.

We will keep you posted as the corresponding releases approach.

For the time being, we have fixed some small imperfections in ArionBench using RCSDK v2.4.2:

– We have extended the duration of the benchmark while leaving the benchmark values unaffected. This makes the benchmark more stable in super-fast computers (we have received some really high benchmark entries this week).

– The counter of seconds overlaid in the final render was broken in the first release of ArionBench. The new one also overlays what build was used (32-bit or 64-bit).

– In software-only mode, ArionBench was (wrongly) leaving one CPU thread idle. That problem is fixed now.

The updated ArionBench will most likely be uploaded over the weekend.

Thanks for watching.

Fantastic news: nVidia TITAN


nVidia has released a new generation of video cards (TITAN). We’re still running tests to confirm, but our first impressions are extraordinary:

A high-end TITAN card is more than twice as fast as a Kepler 680.

If this wasn’t important enough, TITAN cards ship with 6GB. This, combined with the new features for RAM economy in Arion v2.4.1 make the old memory constraints that people used to associate to GPU rendering fade away.

This is great news to Arion users. Good job, nVidia!

Arion Benchmark


We have just released ArionBench.

ArionBench is an Arion-based software tool designed to benchmark the CPUs and CUDA GPUs available to your system.

ArionBench is based in RCSDK (the Arion core), so it is guaranteed to squeeze each and every flop in the computing devices present in your system.

Special thanks go to Marco Podrini (podro), who gently contributed the ArionBench scene.

In order to download ArionBench:

1- If you are a customer or a DEMO user and own an Account ID already, just log-in to our website and download ArionBench from the Customer Area.

2- If you don’t own an Account ID yet, create one and download ArionBench from the Customer Area.

In order to submit your own entries, simply send the image(s) output by ArionBench to

Note that the listings in the ArionBench page are reviewed (manually) by our team to ensure their validity. This means that your submissions won’t be displayed immediately.

We expect ArionBench to become a valuable resource for our customers, who often ask us what GPUs they should buy for optimal performance. But beyond this, we hope that ArionBench will become a reference in the GPU/CUDA world, as it provides a clean and reliable way to benchmark the ray-tracing capabilities of different hardware architectures.
