Denoiser’s new approach. Better integration in the render engine. One-pass render, multi-layered MXI, the Denoiser image is treated as another channel and is included in the MXI file, so its information does not get lost; better memory management because of tiling options and new fine-tuning options to control the Denoiser strenght.
Denoiser parameters exposed:
Maximum Tile Size.
Color Influence (kc1).
Color Influence (kc2).
Feature Influence (kf).
Final Pass Strength (kc4).
A new modal panel shows up while the render is being re-denoised.
New “refresh” controls in the render viewport to refresh the render, the denoiser channel or both.
New option for Channel controls positions in Preferences > Appearance (Bottom-Left and Bottom-Right). Shortcuts on Windows: Ctrl + Alt + NumPad 1 and 2. Shortcuts on MacOS: Option + Command + NumPad 1 and 2.
New option for Refresh controls positions in Preferences > Appearance (Top-Left, Top-Right, Bottom-Left and Bottom-Right). Shortcuts on Windows: Ctrl + Alt + NumPad 4, 5, 7 and 8. Shortcuts on MacOS: Option + Command + NumPad 4, 5, 7 and 8.
Command line parameter -denoise removed. To activate the denoiser through the command line the user must enable the denoiser channel. Example: -channel:denoiser,on,8,png
The Denoiser image output path field has been removed from the panel as now it’s treated as any other channel; thus, the denoised image will be saved next to the main render and with the same name plus _denoiser.
Denoiser auto-configuration now sets Position channel in world coordinates, and Normals channel in camera coordinates by default. If the user enabled any of those channels, denoiser auto-configuration will respect the channels’ configuration set by the user.
The Denoiser will be applied in “preview quality” for intermediate SLs until SL 12. For SL 12 and beyond the denoiser runs in “final quality”, as well as for the last denoiser update when the render ends, no matter the final SL.
Default Priority set to “Below Normal”.
The mximerge application -coopdenoiser command-line flag has been removed.
The Draft engine disables extra-sampling and continues instead of failing when extra-samping is enabled.
Process Priority becomes an application setting, still overridable by command-line parameter -p or -priority.
Deprecated command line parameter -channels removed.
Wrong data issues with TIFF images and LZW compression on Linux and Windows platforms (including Maxwell Cloud nodes).
Maxwell Render never ended in nogui mode if the denoiser was active, and a forbidden denoiser parameters combination was set by mistake in the MXS: auto-configure:fast + shadow-denoiser:on.
BSDF blending proportions of materials could not be accurate when the material was applied to an object with object opacity different than 100%.
Intensity correction was not correct for some additive materials.
Crash with reflectance channel + material with reflectance textures with no tiling.
The License Activator on Mac was copying the floating licenses in the wrong folder.
(MacOS only) Quicklook had a memory leak.
In FIRE CPU (CPU Draft engine) Spot Lights in projector mode were not working.
MaxwellScatter extension removes MaxwellScatter extension from the scattered objects (if they have).
Benchwell stops sometimes before the benchmark test has finished. We don’t allow uploading the results in that case.
NVIDIA Ampere graphics cards support.
Multilight is now supported by the GPU engine.
Multi-GPU dynamic balance. Less samples are expected from cards that had less performance in past rendering passes.
Emitter + BSDF now works in GPU. It is restricted to one emitter per material.
Samples rebalance: Threads of one pixel can help other pixels if they need to. This helps that the image sampling level is more homogeneous. This can make that, in some scenes, Maxwell will require more time to reach the same SL, but more complicated parts of the image will have less noise at the same SL. Also, less computing power will be invested in easy parts, like the sky. In general, the computing power will be used more efficiently.
Speed improvement in multi-gpu.
Improved the way in how certain calculations are done within the GPU engine that should help minimize certain precision issues regarding two surfaces being too close to each other and far away from the camera. (i.e. putting an emitter too close behind an AGS could make the rays skip the emitter if they are far from the center of the scene).
Render Region and Blow-up Region are not supported in the GPU engine, now the region is reset to Full Frame before the render starts.

GPU stopped at a much higher SL than requested.
GPU crashed when having more than one emitter per material.
GPU ghost bsdf (Transmittance white + Nd = 1 + K = 0) was rendering as opaque if the material had more than one bsdf and the attenuation was set to 1 nm.
BSDF blending proportions of materials might not be accurate when the material was applied to an object with object opacity different than 100%.
Intensity correction was not correct for some additive materials.

Cloud job resolucion with locked pixel aspect was not taking into account the original output resolution of the scene and used 4:3 always instead.
Linux: Wrong file type filter on missing dependencies dialog when sending a cloud job.
There were some missing render parameters in the network job wizard UI: Render Engine, Motion Blur, Displacement and Dispersion.
