InnoBright Technologies has released Altus 2.0, the latest update to its render denoising software, splitting the product into two editions: the GUI-based Altus Studio and the GUI/command line Altus ServerPro.
In separate news, the company has also released a dedicated version of the software for Redshift, while further integrations with Arnold and Nuke are
in beta now available.
Denoise renders generated in common third-party render engines as a post process
Launched in 2015, Altus automatically removes noise from ray traced images generated using Monte Carlo methods as a post process.
According to InnoBright, this combined rendering and post-processing workflow accelerates Monte Carlo renders by 200-1,200% over simply generating an equivalently noise-free image in the host render engine.
Although most of the key renderers with which it works, including V-Ray, Corona and RenderMan, now have their own native denoising systems, InnoBright claims that Altus generates higher-quality results, and sometimes does so faster than the native denoiser. You can see its benchmark tests here.
New separate editions for individual artists and larger studios
Although it’s a nice round number, Altus 2.0 doesn’t actually add new features: InnoBright puts out updates every few months, so it’s mainly bugfixes and performance improvements this time round.
What it does do is split the product into two editions: Altus Studio and Altus ServerPro.
Altus Studio is a node-locked, GUI-based edition of the software, aimed at individual artists. It’s priced equivalently to the original floating licence, at $299/year.
Altus ServerPro is aimed at studios looking to run Altus on a renderfarm, and combines Altus Studio with the original command-line denoiser. It’s a floating licence, and costs $399/year.
However, to judge from the newsletter, the update primarily focuses on performance improvements, with a new memory limiter “to allow Altus to internally select a max-tile-size for higher speeds”.
Altus ServerPro also now has “accelerated pre-processing”, and caches pre-processed frames in animations.
The GUI edition, Altus Studio, gets a “makeover”, with the option to preserve output and layer names, and full support for data and display windows.
Updated 8 August 2018: innoBright has released Altus 2.2.
The update focuses on reducing the file sizes for denoised images, introducing 10 alternative compression methods which the firm claims can shrink a file in EXR format by “up to 90% of its original size”.
Users can also now output at 16-bit colour depth as well as 32-bit, which should further reduce file size.
Again, the online changelog hasn’t been updated, but you can see a list of changes in this email newsletter.
Updated 17 October 2018: innoBright has released Altus 2.3. It’s mainly a workflow update, improving error reporting in Altus Studio and adding support for font scaling on Hi-DPI displays.
Updated 18 December 2018: innoBright has announced Altus 2.4. It pushes changes from previous releases to the Redshift edition of the renderer, as discussed in the firm’s email newsletter.
Updated 15 April 2019: innoBright has released new integration plugins for Houdini – it integrates denoising into the software directly as a COP node – and Clarisse.
