RELEASE NOTES FOR MARI 2.0v1

Release Date

14 March 2013

Best Bits of

2.0v1

• Layers, accessed from either the Layers menu or from within the Layers

palette, allow you to set up complex layer stacks for channels. For more

information regarding layer integration, please refer to the Layers

chapter in the Mari

User Guide

• Procedurals and adjustments can now be added using the Layers menu or

palette. Procedurals and adjustments contain many of the former shader

modules.

• Channels now contain layer stacks with mask, procedural, and

adjustment data. Channels can be used in shader component inputs to

specify how shaders impact individual channels.

• Shaders no longer operate on a modular system. Instead they use inputs

to control how lighting, ambient occlusion, and specularity (among other

components) interact with given channels.

• Channels, shaders, and layers can now be imported and exported, either

in a full or flattened state.

• Sharing layers into a layer stack, or as a new channel, allows you to

quickly transfer paint made in one layer to another.

• New selection methods allow you to select, lock and hide patches,

objects, channels, and faces (or a combination of these).

System

Requirements

Officially supported operating systems

• Windows 7 64-bit

• Linux 64-bit operating system (Fedora 12 or Red Hat Enterprise Linux

5.4)

NOTE: Some newer Linux distributions have changed their network device

configuration handling and won’t work with Mari without some

configuration changes. Known affected distributions at this time include

Fedora 16, Red Hat Enterprise Linux 6, and CentOS 6 on certain, notably

Dell, hardware. Please see our FAQs for more information:

RELEASE NOTES FOR MARI 2.0v1 System Requirements Minimum hardware requirements • Quad-core processor • 250GB disk space available for caching and temporary files (or a minimum of 50GB if you're working on a small project) • At least 4GB RAM • Display with 1680 x 1050 pixel resolution • An NVIDIA or AMD graphics card with at least 1GB of RAM and OpenGL 3.
PAGE 3
RELEASE NOTES FOR MARI 2.0v1 New Features New Features Layers • Mari now has a more robust layer system that integrates with channels and shaders. Either from the Layers menu or from within the Layers palette, you can create: • layer stacks, • layer masks, • adjustment layers, • procedural layers, and • layer groups.
PAGE 4
RELEASE NOTES FOR MARI 2.0v1 New Features Shaders • Mari’s shaders and lighting have been improved: • The default shaders Current Channel, Layer and Below, Layer, and Paint Target shaders support Flat, Basic, and Full lighting modes and have shader components that allow for channel inputs. • The number of lighting shaders available has been extended to include the Phong, Blinn, Beckman and Cook Torrance models. You can also mix-and-match different diffuse and specular models.
PAGE 5
RELEASE NOTES FOR MARI 2.0v1 New Features Patches • Fill menu options have been added to the Patches menu and the rightclick context menu on the canvas under Patches > Fill. Options include: • Black, • Gray, • White, • Foreground, • Background, • Transparent, • UV Mask, and • Wireframe. The selected patches of the selected layers are filled with the selected color, transparency, or mask, and can be applied to an entire model by selecting all patches.

RELEASE NOTES FOR MARI 2.0v1 New Features specifically the sections on layer caching on page 231 and 240 of the Mari User Guide. Import and Export • Importing and exporting channels has been updated. These options can be found under the Channels menu or by right-clicking in the Channels palette. Options for exporting channels include: • Export Current Channel, • Export All Channels, • Export Everything, • Export Current Channel Flattened, • Export All Channels Flattened, and • Export Everything Flattened.

RELEASE NOTES FOR MARI 2.0v1 New Features For more information on importing and exporting, please refer to the Exporting and Importing Textures chapter on page 140, or for more specific information on importing or exporting channels or layers, please see the Layers chapter or Channels chapter in the Mari User Guide. Project conversion • When converting old projects to Mari 2.0, a dialog appears to warn you that conversions are permanent and cannot be undone.
PAGE 8
RELEASE NOTES FOR MARI 2.0v1 Feature Enhancements Miscellaneous • In the UV view, overlay text showing the patch sizes has been changed. It now uses abbreviated notation, such as 4K instead of 4096x4096, for all of the non-current image sets, and displays all active patch sizes. • New options have been added to the HUD Manager, and existing options have been reorganized. • Mari’s HUD includes an option to display the maximum number of used texture units.
PAGE 9
RELEASE NOTES FOR MARI 2.0v1 Feature Enhancements • Add Channel, Remove Channel, Duplicate Channel, Merge Channel, and Convert Channel, • Bake Attribute and Bake Shader, • Alpha to Mask and Mask to Alpha, • Export Modified, • Save Shader, Load Shader, Duplicate Shader, Add Surface Shader, and Remove Surface Shader. A few actions have also been moved within the action tree in the same dialogs. These actions include: Lock Channel and Unlock Channel.
PAGE 10
RELEASE NOTES FOR MARI 2.0v1 Bug Fixes • BUG ID 32840 - The Shaders dropdown has been removed from Render Turntable, which defaults to the currently selected shader. • BUG ID 32959 - The diagnostic turntable has been modernized so that the dialog lists 2.0v1 channels, and renders the checked channels. • BUG ID 33552 - On the Clone Stamp toolbar, the Source dropdown menu alphabetizes the channel options.
PAGE 11
RELEASE NOTES FOR MARI 2.0v1 Known Issues & Workarounds • BUG ID 33227 - An invalid user shortcut assignment for Bake On New Channel was linked to a non-existent action that caused Mari to overwrite a valid shortcut assignment. • BUG ID 33355 - Shortcuts assigned to collection items (such as lights or projectors) displayed the assigned shortcut icon in the wrong location in the palette.
PAGE 12
RELEASE NOTES FOR MARI 2.0v1 Known Issues & Workarounds • BUG ID 13294 - Windows: Mari sometimes crashes when trying to load data on large projects due to the program exhausting all Window manager objects. To reconfigure the user object limit: • Open regedit and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\NT\CurrentVersion\Windows, and • Edit USERProcessHandleQuota to a larger number. If this number gets too large, you may also have to modify GDIProcessHandleQuota.
PAGE 13
RELEASE NOTES FOR MARI 2.0v1 Known Issues & Workarounds • BUG ID 15810 - The black borders at the edge of the canvas in Perspective view are selected, if an object overlaps the borders when a selection is made using the Marquee Select tool, with the selection mode set to Magic Wand. • BUG ID 16324 - Windows only: you cannot currently import an image into a channel using a relative file path. To work around this, use an absolute path when importing images.
PAGE 14
RELEASE NOTES FOR MARI 2.0v1 Known Issues & Workarounds • BUG ID 20510 - If you find that the startup time for Mari is longer than usual, please check that the LIC files in your RLM licensing data folder do not refer to obsolete server ports. If they do, place them in another directory and restart Mari. • BUG ID 22099 - The way that Mari converts quad faces to triangular faces is different to other applications. As a result, normal map renders from other applications may not always match.
PAGE 15
RELEASE NOTES FOR MARI 2.0v1 Developer Notes • • • • To avoid reaching these shader limits on large projects, try the following workarounds: • hide groups and layers, or • cache groups and layers. BUG ID 34690 - Flattening or caching layers or channels on complex projects may cause Windows to reset the graphics driver due to the long processing time. To work around this issue, you can try to flatten or cache fewer layers at a time, or reduce the value of the Max Render Size For Baking setting.

RELEASE NOTES FOR MARI 2.0v1 Developer Notes • • • • • • • • • • • • Bug Fixes The Foundry removed. Other related actions, such as shader baking and shader copying have also been removed. The functions findLayer() and layer() have been added to the LayerStack class in Python. Information regarding the old modular shader system in the Python API documentation has been removed. The new function GeoEntity.createPtexChannel() has been added.
