Mari 4.6v4 Release Notes

Release Date

13 July 2020

System Requirements

NOTE: Mari increases its level of performance with newer, more advanced hardware configurations. However, Mari is tested and capable of operating on many older, prior-generation systems. For this reason we are listing below-minimum requirements, which are recommended, and on which tests have been performed. Your particular needs may vary from that of other users.

Officially Supported Operating Systems

Linux Desktop Managers: Mari is officially tested on GNOME and MATE. While it generally performs well on other desktop managers like KDE, most of our bug fixes will target those specified above. Some desktop managers like XFCE have not been tested with Mari and therefore will not be supported.

Minimum Hardware Requirements

*Displacement preview is currently only available on the cards and drivers that support OpenGL 4.0 or newer.

Recommended System Requirements

*The use of virtual memory improves stability and helps prevent data loss on large projects.

'Recommended' does not guarantee that it meets your particular needs.

Tested Hardware

The configurations listed below are those that Foundry have tested with Mari. Due to the constantly changing nature and wide variety of computer hardware available in the market, Foundry is unable to officially certify hardware. The list below can be used as a recommendation and does not guarantee that it meets your particular needs.

Please download and install the latest graphics driver from the NVIDIA or AMD websites, and ensure that you are using 8.982.1 drivers or higher for AMD cards.

New Features

Limited Patch Range Baking

In previous versions of Mari, baking would flatten the upstream graph results for all patches within a project even if the results would be masked for a small range of patches downstream. This would waste a lot of computation time when your objects had a large amount of UDIMs. Mari 4.6v4 introduces the ability to use a Limited Patch Range when flattening upstream results to a Bake Point node. You can now limit baking to the required UDIM patches by specifying a patch range and then select a background color for patches outside the given range - reducing bake times and giving the user more control to reduce project complexity with Bake Points.

Export on Bake

Users now have the option to automatically export the flattened results of a Bake Point to disk after updating its upstream results. If Export on Bake is enabled, Mari will rewrite textures to a given path when patches are baked instead of requiring the user to manually export the updates. This streamlines the process of sending your iterative updates to other applications.

Transform Tool: Local Space Mode

A new Local Space Mode has been added to the existing Transformation Tool allowing you to manipulate the transform gizmo along the object axises once it has been rotated. Manipulating the Transformation Tool handles while holding the CTRL key now edits the transformation in iterative steps. Additionally, the hit area for Transformation Tool has been increased, removing the requirement of pixel perfect handle picking.

New Features

Open Source USD Mesh Importer Plugin

We have taken ownership of a mesh importer plugin for USD originally developed at Pixar. The plugin currently only supports UsdGeomMesh and UsdGeomXform primvar types. It does not yet support UsdShade, UsdGeomCamera, UsdLux or other Usd Schemas. However, we have added native support for OpenSubdiv parameters on UsdGeomMesh, which requires CAPI extensions introduced in Mari 4.6v4.

The plugin source code is available for download at:
