The Foundry MARI 3.0 v3 [En]

Painting
MARI’s cutting-edge paint tools give you the freedom and flexibility to create truly stunning effects and detail, with the added advantage of full triplanar projection for faster scene set-up.
Being able to import custom ABR brushes from Photoshop means that you can keep the brushes you know and love, while at the same time benefiting from a fully customizable brush engine. Additional brush features include a 'healing' brush for seam removal and duplication of texture detail and a ‘slurp' brush for smearing and dragging texture.
It’s possible to simulate a vast range of reflective surfaces using MARI’s advanced spherical environment mapping. All painting and shading tools are available in 3D projection paint mode and 'flat' UV paint mode, while tiled textures with masking make it simple to quickly cover large areas on models. A UV-less workflow (PTEX) lets you adjust texture size on a per-face level, allowing for near-limitless detail.
MARI gives you masked filters for colour correction, noise and masked blend constant color, with the added bonus of being able to preview all filters in real-time. An advanced channel masking engine supports mask painting and surface falloff and enables masking one channel to another.
Advanced layering
The full power of a layer-based workflow along with adjustments, procedurals and advanced masking means that you can paint faster and with greater control than ever before with MARI. Procedural layers make it easy to create the look you want, seamlessly blending procedural and painted detail with the same toolkit. A powerful procedural engine is built into the heart of the layer stack, offering fluid, GPU-accelerated real-time procedural noises, patterns, projections and more.
Realistic interactive preview
With MARI, you can create normal maps on the fly from bump maps, making it simpler and easier to generate and manipulate textures. Shadow support lets you cast real-time shadows on objects from multiple light sources and provides a customisable real-time 3D shader preview for things like specular highlights, displacement preview via bump mapping and colour correction. MARI also allows you to import multiple camera moves through which to view your model.
Geometry handling
MARI handles animated geometry and animated textures with ease, making it possible to isolate, select, mask and hide geometry per patch and face. Being able to have overlapping UVs means you can re-use the same texture across 3D models in any shared UV space, as well as handling multiple objects, versions and instances, with or without baked animation.
Handling very large 3D model data sets becomes simple with MARI’s ability to scale to over 1 million polygons for a single topology or mesh. MARI can also support large textures of up to 32K x 32K pixels and thousands of textures per model across different channels, allowing for almost infinite amounts of detail.
Color management
With OpenColorIO (OCIO), the open source color management solution from Sony Picture Imageworks, you can handle color transforms and image display across multiple applications by setting up a single profile to provide consistent colors across the board. A key tool in simplifying the color management process, OCIO is suitable for both visual effects work and animated features and is specifically geared towards post-production work.

MODO rendering and baking
Access MODO’s advanced photorealistic renderer directly within MARI to check the final-render quality of your work as you paint, helping you iterate faster to achieve the look you want. In addition, you can now use MODO’s powerful baking engine to bake textures from within MARI; new baking presets can be created in MODO, offering an extensive range of looks.
OpenSubdiv support
New support for OpenSubdiv geometry in MARI lets you work with subdivision surface (SDS) meshes, without the need to translate or pre-subdivide them. With subdivision surfaces, you can view and work with a more faithful representation of the final rendered smooth surface, and with accurate UV layouts for each level of subdivision.
Color space management
Building on the previous introduction of OpenColorIO, MARI 3 delivers new flexible, artist-friendly color management workflows. With color space properties available on both images and on individual channels of multi-channel images, the requirement to preprocess or post-process images into the correct color space is eliminated, saving time and reducing errors.
Exposed node graph
Advanced users can now create and edit channels and layers in a more powerful, efficient and visual manner with phase one of the exposure of MARI’s node graph. As an option to using the traditional layer system to add channels and layers, you can now work directly in the node graph, selecting and connecting nodes to build your final textured surface.
Custom group nodes
With new access to the node graph, advanced users can combine frequently used functions into custom group nodes that appear as a single entity, similar to NUKE’s Gizmo feature; you can select which parameters to expose, reducing unnecessary complexity. Gizmos can be exported for use in other projects, or shared with others.
Arnold, V-Ray, Unreal and Redshift shaders
New shaders designed to simulate those used in industry-standard rendering and games engines—Arnold, V-Ray, Unreal and Redshift—let you paint your textures in their intended final context, providing more realistic previews and giving you the confidence that your textures will work as expected.
FBX geometry support
Work in conjunction with a vast range of third-party and proprietary 3D solutions and source material providers, with new support for reading geometry from the widely adopted FBX format files. With MARI 3, you can view a tree widget of the contents of your FBX file and choose to import either the entire hierarchy or selected child nodes.
Session scripts
New Session Scripts in MARI 3 let you create a lightweight archive of a project that can be combined with other archives, keeping all data intact. The ability to merge projects lets you see assets in context with other assets, share useful data for reuse, or set up project templates.
Rendering integration APIs
MARI 3 delivers four new APIs that help studios integrate MARI with their rendering pipeline, reducing the need to transfer files between applications and resulting in faster iterations and a more accurate understanding of the final context. Potential applications include real-time viewport display, network rendering and texture baking.
Enhanced texture transfer
MARI’s Texture Transfer system uses generated point cloud data to transfer textures between two different models, without the need for matching topology or UVs. In MARI 3, you can use this data to generate height and normal maps between high and low polygon models, seamlessly blur across patch boundaries, and correctly transfer overlapping UVs.
Entity locators
Translate, rotate and scale geometry more easily with new Entity Locators. Entity Locators offer a 3D manipulator that improves visual accuracy when transforming geometry inside MARI's viewport using the Move tool.
Safe mode
A new Safe mode in MARI 3 offers easier troubleshooting by isolating the user's involvement and environment issues during debugging. Being able to identify and isolate critical points faster will help resolve issues and improve the customer support process.
Extended access to selection groups
Developers and TDs can now access selection groups through the Python API, allowing them to manipulate various parts of a geometry entity through scripting and to automate related functionality. In addition, artists can now access selection groups directly by clicking on them on the model in the viewer.

Версия 3.0 v3:
• A new Python function named runGLSLCode has been added. It runs GLSL code and writes the result into the specified ImageSet with optional blending.
• It is now possible to automatically merge selection groups with the same name imported into Mari .
• In the Channel Transfer dialog, a new option to set the texture resolution of the destination channel has been added.
• Mari now detects whether to subdivide each Alembic geometry piece, based on subdivision flags set in the file.
• The accuracy of mip-map generation has been improved, at the cost of performance, by linearizing data before downsampling. To disable this, and restore legacy functionality and performance, a new option has been added to the Preferences called Mip-Map Generation.

Версия 3.0 v2:
• A button has been added in the Node Properties palette to delete all the node property panels.
• It is now possible to view detailed information about a node by selecting it and either pressing I, or right-clicking and selecting Edit > Info Viewer.
• There is now an R (reset) button in the Mari Preferences, in the Node Graph tab for the Advanced View option.
