Maya - Version History

Version v5.2.2 - 15 Jun 2023

COMPATIBILITY:

• Added support for Maya 2023 and 2024.

FIXES:

• Updated the library file libeay32.dll in Maxwell Render installation.

Version v5.2.1 - 15 Dec 2021

COMPATIBILITY:

• Built for Maxwell Render 5.2.1.49.

• Added support for Maya 2022.

• Dropped support for Maya 2016 and 2017.

ADDED:

• New "Denoiser" channel.

• New Substance Painter Assistant.

• New Substance Designer Assistant.

• Added support for XGen interactive groom hair (the changes are still not interactive in Fire). Hair types by groomable splines, controlled by expressions or placed manually by guides can be rendered with Maxwell using the option in the Generate menu > Convert to Interactive Groom…

IMPROVED:

• The plugin now uses the new Maxwell Render 5.2 Denoiser implementation:

  • Only one render pass is needed

  • The Denoiser information is now included in the MXI file

  • The Denoiser channel can be recalculated after opening the MXI.

  • The renders with Denoiser can now be easily resumed.

  • The Denoiser can be calculated in tiles so its memory consumption is very much limited.

  • New fine tunning options control the Denoiser effect.

• The Denoiser tab in the Render Settings panel now includes new options.

• MXS export and Studio export now takes Simulens and other Render parameters into account.

• Maxwell’s "Select Material" dialog now shows Maxwell Assistant and Referenced materials too.

CHANGED:

• The Denoiser "Start with SL" default value has been changed from 4 to 8.

• The Denoiser "Start with SL" value can now be set from 3 to 50.

• Maxwell Volumetrics "Field Density" parameter default value is now 1.0.

• The "Create a Maxwell Volumetric Object" button creates the new volumetric object with a base transform scale of x100.

• Maxwell Hair "Render Type" values have been renamed from "Cones", "Blades", "Curves" to "Cylinder", "Flat", "Curve".

• The default Maxwell hair type was changed to "Flat".

FIXED:

• In some cases, the transform values of the exported element were wrong in multi-level groups.

• Could not find the license if the license file contained non-ascii characters.

• It was not possible to assign a material to the Volumetric objects.

• Transformations with negative scale caused wrong item transformation values in Maxwell Studio.

• Maxwell Material Assistant: drop-down types were not exported correctly.

• In the case Maxwell Material editor is visible inside more than one panel, the Material preview was shown in one panel only.

• Many Hair assistant preset values were wrong.

• The plugin set texture channel value 1 for all the textures connected to the Color channel of any Assistant, but only the hair assistant should behave like this.

• The Hair Assistant presets didn’t set the preset color textures.

• The custom alpha assignment had some inconsistencies.

Version 5.1.1 - 16 Jul 2020

COMPATIBILITY:

• Built for Maxwell Render 5.1.1.33.

Version 5.1.0 - 13 May 2020

COMPATIBILITY:

• Built for Maxwell Render 5.1.0.29.

Version 5.0.6 - 29 Apr 2020

COMPATIBILITY:

• Built for Maxwell Render version 5.0.2.21.

• Added support for Maya 2020.

• Added support for MacOS operating system.

IMPROVED:

• Added an option to activate or deactivate the Grass, Scatter or Subdivision extensions per node. You will find a new dropdown at the top part of their parameters panel.

• Now the Maya’s File Path Editor tool also takes into account referenced mxs and mxm files so the user can now repath some or all of them to a different folder (this doesn't affect the paths of the textures or referenced inside those mxm or mxs files). This was already working for the textures used in the scene.

• The exporter to Studio only exported what was selected; now, if there are objects selected, only the selected objects will be exported and, if there is nothing selected, everything will be exported.

• When exporting to Studio, no camera was included; now, if there are objects selected, only the selected cameras will be exported and, if nothing is selected, all of them will be exported; in both cases, the active camera will be exported. When launching a render, only the active camera is sent.

• Export to Studio, Pack and Go, File > Export and File > Export Selection now is exporting the group hierarchy to the mxs file. The mxs file generated when rendering will still be flat (so it exports the smallest file possible).

• Export to Studio, Pack and Go, File > Export and File > Export Selection now is exporting the hidden geometry and their materials.

• When exporting to Studio now the environment settings are also exported.

• If no path was specified for storing the mxs file, the export to Studio, Network or Maxwell Cloud commands failed; now an untitled.mxs will be saved in one of these folders depending on the operating system: 

  • Windows: C:\Users\<username>Documents\maya\projects\default\scenes\maxwell\

  • MacOS: ~/Documents/maya/projects/default/scenes/maxwell/

• The viewport preview of the sky was projected onto a too-small sphere so when the camera clips were active the preview of the sky could disappear. Now the sphere is bigger and will work better in most of the scenes.

• The naming and icons of the Maxwell nodes now are more specific; these have been improved: Grass, Scatter, Maxwell Reference, Sea, Sky Preview, Bin Object, RFRK Object and RFRK Particles.

FIXED:

• The “Update from File” button in a referenced material made the corresponding faces disappear in Fire.

• Fire was not stopped when a normal render was launched.

• The Pack and Go tool was not exporting the .mxs file or the Maya scene file in the selected location.

• The plugin could generate Maxwell materials with the texture slot active but without a texture inside; this could make the GPU engine fail.

• Maxwell Sea was not exported when using the export selection method.

• Maxwell Scatter typo: Length Map should say Scale Map

• Fixed obsolete code.

KNOWN ISSUES:

• On Mac, mxs references, proxies and extensions (grass, scatter, sea,...) may not display correctly in the viewport and may produce some instability.

New things and improvements:

• Added support for Maya 2019.

• Added support for Maxwell material representation in Viewport 2.0 (Core Profile) for Maya 2017 and newer; in the case of Maya 2016 Legacy Default Viewport has to be used but the features regarding viewport shaders will be the same as in previous versions.

  • Added support for showing in viewport the color or texture of Reflectance 0º and 90º.

  • Added support for showing in viewport the transformations of textures loaded in Reflectance 0º and 90º (Invert, UV Rotation, Brightness, Contrast, Saturation and Hue from “Maxwell Image Controls” and Repeat UV and Offset from “place2dTexture”)

  • Added support for showing in viewport the textures loaded in Layer Masks and BSDFs Weight Texture with support for Invert and UV Rotation from “Maxwell Image Controls” and Repeat UV and Offset from “place2dTexture”

  • Added support for showing in viewport any texture using “Enable Viewport Override” with support for Invert, UV Rotation, Brightness, Contrast, Saturation and Hue from “Maxwell Image Controls” and Repeat UV and Offset from “place2dTexture”

  • Added support for showing in viewport an approximation of the transparency set in Transmittance as well as textures with support for Invert and UV Rotation from “Maxwell Image Controls” and Repeat UV and Offset from “place2dTexture”

  • Added support for showing in viewport an approximation of the blending between Reflectance 0º and 90º (colors or textures) affected by roughness value.

  • Added support for showing in viewport an approximation of the blending of multiple BSDFs as well as multiple layers (limited to 32 elements, that is BSDFs or layers) taking into account Normal or Additive blending modes.

  • Added support for showing the main color and texture of the assistant materials in the viewport.

  • Added support for showing any other texture of the assistants through “Enable Viewport Override” with support for Invert, UV Rotation, Brightness, Contrast, Saturation and Hue from “Maxwell Image Controls” and Repeat UV and Offset from “place2dTexture”.

  • Added support for showing environment viewport preview for Windows and Linux (in Mac it’s not working as it is based on OpenGL 2.0 and in Mac it’s only supported from version 3.2 and up. We’ll try to add support for this in future updates).

• New Maxwell Material Preview area in Attribute Editor; bigger, more useful, collapsible and detachable).

•  

  • Added a bigger material preview area that can be set to three different sizes.

  • Added engine selection options for the material preview (drop-down and right-click menus).

  • Added controls for Sampling Level (SL) and Time limits as well as the number of threads for the Material Preview.

  • Added a drop-down menu to be able to select the preview scene from the ones available at the Maxwell installation preview folder.

  • Added a text box where to store custom information about the material.

  • Added a toggle button to change from On Demand preview update mode to Automatic.

  • Added a button to edit the material in Maxwell Material Editor (MXED).

  • Added buttons to detach the material preview to a floating window.

  • Added update preview button.

• Added new buttons to create embedded, referenced and assistant materials (new).

• In the case of MXS references, we added new object ID options, so you can choose between Container (it will show the one of the MXS reference itself, so it will be one single color), Content (it will show the object ID of the individual objects inside the reference, so it will show several colors) or Recolor (this will generate new random colors for the objects inside the reference which will be persistent between renders).

• Reorganized assistant materials’ options and default values so they match the ones in MXED; also added some missing texture chips and fixed some problems using textures.

• Added Hair assistant material.

• Added an alternative custom saving folder for the Online Gallery downloads in Preferences.

Fixes:

• Launching a region render crashed Maya when the image was returned to the image frame buffer.

• When using “Export selected” from File menu with Pack and Go, all the materials of the scene and related files were exported, instead of only the ones related to the selected objects.

• The plugin was ignoring Maya lights and MXS references when exporting under certain circumstances.

• Maya crashed if the plugin could not find the right version of Maxwell. It now informs of the problem and disables the plugin.

• MXS references were not displaying correctly in the viewport in the case of grouped geometry that had transformations applied to the group (although they rendered fine).

• Some of the fields were showing a light grey background while Maya default color is dark grey.

• Instances with negative scales exported from Maya were not opened in the right place in Studio (although they rendered correctly).

• Maya was crashing when trying to open another file after saving one.

• When Maxwell was set as default renderer, Render Settings panel showed empty.

Version support changes:

• Dropped support from Maya 2012 to 2015 (included) as some of the new features were not able to work on the old versions.
