This forum will be used to announce new features and release

A new version of Maxwell is out. It's Maxwell It is mostly a bug fixing version, but there are some additions and improvements here and there that are worth highlighting:
  • We have added a new small toolbar to the bottom of the Material Editor layer tree to help with some common tasks. You can check this link to learn more about it: ... on-Toolbar
  • We also gave some small touches to the interface in Studio, the MXED and the Cloud interface: the material preview refresh button is slightly changed, some icons were renewed in Studio too and some new buttons added to the Cloud interface.
  • The GPU engine received several improvements: better illumination matching with the CPU, better firefly cleanup, Z-clip is now working fine,..
  • The plugin for Rhino 6 now has all the material assistants accessible from the Global Properties of the material editor. We plan to add a special toolbar for material creation so it's quicker to create or import any material.
  • The plugin for Archicad now supports Archicad 24
You can get the installer from the "My Downloads" section in your account at the portal as always:

Here are the full release notes for Maxwell Render and Studio. For more information on the plugins, please check their respective release notes (Version History section) in the documentation page ( ... 32/Plugins)

  • Benchwell charts sorted by benchmark.
  • Command-line parameter -extrasamplingsl accepts value “0” now to prevent some errors.
  • The UI colors of the License Activator didn't allow seeing the different fields.
  • Denoiser process could lock Maxwell Render in “-nogui” mode when the output images are in TIF format.
  • Crash in scenes with one-light light groups and Color Multilight.
  • Re-Denoise function disregarded light changes in Multilight for Shadow denoise.
  • Maxwell on macOS got out of full-screen mode leaving a window on top.
  • Activate License... option on macOS did not launch the License Activator.
  • Maxwell didn’t close if the render failed and the denoiser was activated in “-nogui” mode.
  • Wrong data issues with TIFF images and LZW compression in Linux platforms (including Maxwell Cloud nodes).
  • MaxwellScatter extension removes MaxwellScatter extension from the scattered objects (if they have).
  • Benchwell stops sometimes before the benchmark test has finished. We don’t now allow uploading the results in that case.


  • GPU materials have been improved to better match CPU’s ones. This affects mainly materials with transmittance and glossy ones.
  • Extra-sampling + custom alpha stopped the render at the early stages.
  • The illumination differed too much from the CPU engine in some scenes.
  • The roughness of dielectric materials did not match the CPU result.
  • Direct lightning on dielectric materials did not work as expected.
  • Anisotropy was not working for Roughness 0 materials.
  • Firefly cleanup was not working correctly.
  • Z-clip was not working on GPU.
  • The default value for the “No Tiling” option for opacity values did not match CPU one.
  • GPU engine could crash with empty scenes.
  • Little discrepancies in channel values.
  • Crashes could occur on fire when moving the camera during the preprocess.


  • Some icons have been renewed (different object types and extension icons).
  • Crashes could occur when changing material properties while FIRE was running.
  • Resources Browser widget resizing may crash Studio in some cases.
  • Studio won’t work on a remote desktop (Linux host).


  • New buttons were added at the bottom of the layer structure of the material to ease the creation of layers, BSDFs, emitters, displacement and coatings. Also, added a button to delete components. Please, check here for more information.
  • Two new buttons were added to create a new additive shiny layer and a ghost BSDF (this one can help to create invisible emitters or to easily mask the whole material under it. Check here for more information.
  • The default preview scene changed; the previous “defaultpreview” was renamed to “checkered”, “stage1” to “defaultpreview”, and “stage2” to “ribbed”.
  • The different preview sizes changed from 25%, 50%, 100% and 150% to S, M, L and XL.
  • The Auto-update toggle button changed to something more informative and better looking.


  • Maxwell Cloud: a new button was added to force-stop the cloud render by killing the cloud machine (if the render has already stored any file to the server, it will be kept); this gives the user a tool to immediately stop consuming cloud time.
  • Maxwell Cloud: a new button was added that allows the user to easily copy the render IDs in case they need to report issues with a render in the cloud to the Support team.
  • Maxwell Cloud: the job wizard fills the Render Options panel from the MXS data. In case there is more than one MXS to be rendered, it will use the first one of the list.
  • Maxwell Cloud: message text improved on file overwrite when the user downloads the render results.
  • Removed the confusing message that appears when the user stops a Maxwell Cloud render that hasn’t reached an SL greater than 0.
  • Random crash sending jobs to Maxwell Cloud with multiple renders on it.


  • Crash running Pymaxwell Editor on macOS.


  • Maxwell 5 macOS plugins could end up loading Maxwell 4 if it was installed.

We hope you enjoy it!
