Overview.

The Glyph Software Mattepainting Toolkit (gs_mptk) is a plugin suite for Autodesk Maya that helps artists build 2.5D and 3D environments from multiple camera projections. It developed from a need to more efficiently model and render scenes that rely heavily on projected mattepaintings.

The Tools

The Mattepainting Toolkit for Maya includes:

• Two Mental Ray shaders: gs_projCamMix and gs_const. gs_projCamMix blends camera-projected textures together based on parameters such as occlusion masking, world space distance, and backface culling. A complete list of blending features can be found in the Features section and in the documentation. gs_const is a constant shader with transparency settings designed specifically for the needs of mattepainters, and is intended to be used with gs_projCamMix.

• A Maya UI interface (shown above) for managing a multitude of projections and projection parameters, as well as an arbitrary number of custom mattes and object associations.

• An OpenGL viewport implementation that allows images to be projected onto models in high resolution within Maya's viewport. sRGB viewport gamma conversion is supported for linear color space images. Check out this video for a demonstration.

• Bundler and PLY importers for camera and point cloud data recovered from photographs.

• Coverage maps rendering to isolate areas visible to a shot (render) camera from a projection perspective. Very useful for concentrating paint work.
