Autodesk is introducing all-new experiences for Texture Baking and Install, major improvements to the Viewport, and key enhancements to Substance tools, ProSound and SketchUp import. You will also find speed improvements throughout your process from installation to rendering, and 3ds Max Python 3 now set as default Python interpreter.
The industries you serve are constantly changing and becoming more competitive. Customer demands and expectations are also increasing. New workflows and standards are required. More work needs to be done faster, and on projects that are growing in size and in complexity.
What’s New in 3ds Max 2021
Bake to Texture
Streamlined, intuitive and fully scriptable texture baking experience, with support for PBR ( Physically Based Rendering), Overrides and OSL workflows.
- Modernized tools that support new physically based rendering (PBR) workflows
• Roughness and Metalness maps added in Arnold
• MikkT Normal maps support (industry standard)
- New baked element for map override allows advanced and powerful workflow with OSL and procedural maps
- Streamlined experience
• A more intuitive feature as all settings and functionalities are exposed in a linear way, align with the user journey.
- Fully scriptable for customization and automation.
Note: The legacy Render to Texture and Render to Surface tools are still available in 3ds Max. The goal is to have feature parity before removing the old functionalities.
The online and offline installation process has been overhauled for a simpler and faster experience.
- Faster and fewer clicks to install 3ds Max. Testing showed up to a 50% speed improvement, though results vary greatly based on machine specifications and internet bandwidth.
- In-product messaging to prompt user to install missing or optional components.
Scripting with Python 3
We are investing in improving 3ds Max’s Python support to offer developers and technical artists a modern and robust experience for extending and integrating 3ds Max into production pipelines.
- 3ds Max 2021 comes with Python 3 and an improved pymxs API that gives access to all the 3ds Max features.
- Our integration of PySide2 allows developers and technical artists to create cross-application user interfaces that work seamlessly in 3ds Max.
- Off-the-shelf Python 3 extension libraries are fully supported, extending the reach and power of the tools our user can create.
Note: Python 3 is the default Python interpreter, however Python 2 is still supported when explicitly enabled through a 3ds Max command line switch or environment variable.
Arnold as the Default Renderer
Presenting users with a modern and high-end rendering experience right out of the box.
- 3ds Max 2021 ships with Arnold 6.0
- Supports new Bake to Texture workflows.
- New Scene Converter scripts provided to efficiently convert from V-Ray and Corona materials to the Physical Material.
Physically Based Rendering (PBR) 3ds Max 2021 adds several features to simplify the use of PBR workflows in the viewport when rendering, and when working with real time engines.
- The renderer-independent Physical Material in now the default everywhere, which facilitates modern, physically based rendering and real-time engines to take maximum advantage of it.
- New, simplified PBR Materials specifically intended for simplifying real-time engine workflows.
- The viewport shader for the Physical Material is improved to give a visual appearance that is much closer to the final appearance in real-time engines (game, VR, etc.)
- Full export/import of Physical Material in FBX.
Improved Viewport Quality & Settings
Simpler viewport configuration workflows allow you to produce high quality and high-fidelity viewports which were previously cumbersome to achieve.
- Viewport Settings can now be saved as presets
- New Progressive refinement controls in the UI
- Ambient Occlusion is now always visible when manipulating the viewport
- New roughness support for the Physical Material
- Viewport Statistics Performance improvements
- Shadows for lights are now on by default
Enhanced UI and new shaders improve the overall user experience with OSL.
- The OSL shaders now support a custom UI template designed in Qt designer, as well as several new ways to drive UI from the metadata, allowing a much more visually appealing and useable UI.
- (Some of the) new OSL shaders in 2021:
• Color Correction
• HDRI Environment
• HDRI Lights
• Float and Color Curves
• Camera Projection
• Object Projection
• Spherical Projection
• Uber Noise
Saving scene files with a very large number of assets has been significantly sped up.
- This improvement also benefits Autobackup (Autosave) and Hold operations.
- Files with more assets have greater speed improvements. In our testing, we found that a scene with roughly thousand assets could save 50% faster.
New Chamfering improvements and Weighted Normals modifier
- Chamfer improvements: Providing consistency with the Chamfer modifier work that was added and refined in previous 2020 releases, we have added support for our new chamfer technology to the vertex, edge, and face level component modes of an Edit Poly modifier and Editable Poly object. Users can now utilize the benefits of 3ds Max’s leading chamfer technology to add detail and refinement to their Poly models.
• Enhanced chamfer support for Edit Poly and Editable Poly operations inside of 3ds Max
• Preserves and works with existing UV data when generating new mesh results
• Added support for Uniform, Radial, and Patch chamfer types
• Added support for Edge Depth, End Bias, and Radial Bias control and refinement
• Smoothing support for the generated results so that you can blend the new geometry into existing mesh data.
- Weighted Normals modifier: Based on user demand, we’ve added support for weighted normals to be calculated and applied to models in 3ds max. o Generate new explicit normals for your mesh data faster and better than ever before possible inside of 3ds max.
• Use Area, Angle, or Largest Face weight options to influence the direction of the computed normal results
• Generate hard edge normals for your mesh via defined Smoothing Groups/Defined Hard Edges, UV seams, and/or Edge Angle that you have already placed on your mesh.
• Control the smoothing/blending of the various results to increase the output
FIT & FINISH
We continue to enhance the ATF-based SketchUp importer in an effort to make it the only SketchUp importer necessary in 3ds Max.
- Based on customer feedback, we have added the following options:
• The ability to completely skip importing Hidden Elements from the SketchUp file
• The ability to preserve Layer information from the SketchUp file and use it automatically assign imported objects to matching Max layers
New Substance2 map type, performance improvements, and many new capabilities.
- Updates to latest Substance engine for native SBSAR file loading. No longer need to export maps from Substance Designer.
- Support for up to 8k textures.
- Support for all render engines that ship with Max (Arnold, Scanline, Quicksilver, ART)
- New, scripted tools to quickly set up Substances with a particular type of material or to bake out maps to files.
- The Substance plugin now comes as a separate component to install; therefore, you only need to install it when you need it.
Note: The legacy Substance map is still included, however we may look to remove it in the future.
Improved audio support.
- Added support for 24bit .wav files
- Added support for 88.2kHz and 96khz sample rates.
- Added support for unlimited number of audio clips. (Previously there was a maximum of 100 clips.)
- Fixed sound issue causing audio to play at 50% volume after frame 100.
- The option to export animation only when exporting to FBX is now available in the UI. It was formerly available via scripting only.
- Added support in FBX exporter for Shell material – option to export the original of the baked material.
- Along with Physical Material support, FBX was updated to support exporting and importing OSL nodes in 3ds Max
- Post-Sampling key reduction can be disabled by script. This may be useful when importing subtle animation data that needs preserved when resampled.
3rd Party Developer Tools
Plugin compatibility with 3ds Max 2020, and improvements to Plugin Packaging.
- 3ds Max 2021 supports plugins compiled for 3ds Max 2020, giving users the freedom to migrate when they are ready, without worrying whether their preferred tools and plugins are available.
- The Plugin Package format now supports AMG and OSL shaders, and Scene Converter extensions. This allows a wider range of plugins to use the application plugin packaging format.
- Using the application plugin package format makes it easy to distribute the plugins on the Autodesk App Store, and simplifies development and installation of plugins for 3ds Max.
