Mari was developed by a New Zealand company Weta Digital, which was used in such films as the District 9, The Lovely Bones and Avatar. Mari is intended only for texturing 3D-models. From analogues (Zbrush, Mudbox, Blender, 3d-coat) is different for up to several thousands of large textures (32k to 32k pixels) on the model, greater speed of working with large textures, greater opportunities for visualization, flexible engine, brushes, animation support, and the ability to create animated textures.
Painting:
* Fully customisable brush engine
* 'Paint through' and 'clone from' between layers and textures (including 'clone from' on-surface)
* 'Slurp' brush for smearing and dragging texture
* Paint canvas transform, grid warp and free-form 'pin' warp
* Blur and sharpen, including on-surface, multiple UV patches simultaneously
* Advanced 'healing' brush for seam removal and duplication of texture detail
Environment:
* Filters with real-time preview
* Advanced channel masking engine, including mask painting, surface falloff, masking one channel to another, and by depth
* Supports customisable real-time 3D shader preview (eg specular highlights, displacement preview via bump mapping, ambient occlusion, layer blending modes, colour correction and more
* Customisable tool 'shelves' for brushes, colours, reference images, sharable between artist and projects
* Floating point, 16 bit or 8 bit channels
* All painting and shading tools are available in 3D projection paint mode and 'flat' UV paint mode
* Background plates for reference
* Imports multiple camera moves through which the model can be viewed
Models:
* Obj model format support
* Multiple objects, versions (eg high res or in key character poses), instances, with or without baked animation
* Interactively handles very large 3D model data sets, scaling to over 1 million polygons for a single topology or mesh
* Supports large textures up to 32K x 32K pixels
* Handles thousands of textures per model, over many channels
* Seamlessly supports hundreds of UV texture patches
* Handles animated geometry and animated textures
* Isolate, select, mask and hide geometry per patch and face
* Customisable lighting and rendering modes
* Massive geometry and texture data sets not limited by the amount of RAM
MARI is a creative texture-painting tool that can handle extreme projects. MARI was developed at Weta Digital to handle the massively complex, highly detailed look development work demanded of the texture department by projects such as District 9, The Lovely Bones, and Avatar.
MARI has a creative toolset which puts many stand-alone 2D paint systems to shame, allowing artists to concentrate on painting. The user interface is responsive and fluid. You can paint directly on to models and view the results immediately. Save time and take texturing way beyond what was previously possible.
MARI's unrivalled ability to deal with colossal textures in vast numbers allows their development in intense detail.
