Viewport Renderers

MM Solver comes with specialised Viewport 2.0 renderers designed to add helpful features for use with MatchMove workflows and reviews.

Viewport 2.0 “Renderer” menu.

Currently the following Viewport 2.0 renderers are available.

MM Solver Renderers

Name	Description
MM Standard Renderer	Identical to default “Viewport 2.0”, but correctly works with MM ImagePlane nodes in from hold-outs, either using Hold Out attributes or Use Background shaders.
MM Silhouette Renderer	Identical to MM Standard Renderer, but adds a silhouette outline edge to all rendered meshes in the viewport.

MM Standard Renderer

MM Standard Renderer is a Viewport 2.0 renderer designed to add helpful features for use with MatchMove workflows and reviews.

MM Standard Renderer is different from regular Viewport 2.0 because it can display MM Image Plane nodes with native useBackground shaders (or Hold-Out geometry).

Usage

1) To use MM Standard Renderer, load the mmSolver plug-in (for example open the Solver UI to ensure the plug-in is loaded), then use the Viewport’s “Renderer” menu to switch to MM Standard Renderer.

Enable MM Standard Renderer in the Viewport “Renderer” menu.

2. Use the Maya viewport and playblast as normal.

MM Silhouette Renderer

The MM Silhouette Renderer is used to add silhouette outline edge to rendered geometry, allowing the artist to clearly see the edges of a mesh against an image sequence.

This rendering effect is particularly effective when the geometry contains a Hold-Out effect using a useBackground shader or hold-out attributes (see Set Mesh Hold-Out tool).

Example green silhouette effect on shaded objects.

Note

MM Silhouette Renderer requires the use of the OpenGL graphics API backend; DirectX is not supported.

Usage

1) To use MM Silhouette Renderer, load the mmSolver plug-in (for example open the Solver UI to ensure the plug-in is loaded), then use the Viewport’s “Renderer” menu to switch to MM Silhouette Renderer.

Enable MM Silhouette Renderer in the Viewport “Renderer” menu.

2. Click viewport panel menu “Renderer > MM Silhouette Renderer [Option Box]” to open the renderer settings in the Attribute Editor.

3. Adjust Silhouette settings as needed for desired effect.

4. Use the Maya viewport and playblast as normal.

Settings

The settings for the MM Silhouette Renderer affect all open viewport panels using the same renderer and allow adjusting the silhouette effect, including the color and opacity.

The global settings for the MM Silhouette Renderer in the Attribute Editor.

MM Silhouette Renderer Settings

Name	Description
Depth Offset	The separation between the invisible solid geometry and the wireframe mesh. Adjust to lower values if small-mesh artifacts are visible. Set to 0.0 to create a shaded wireframe effect.
Width	The width of the silhouette lines.
Override Color	When enabled, all objects will use the silhouette color below. When disabled, the wireframe color of the object is used for each object’s lines.
Color	The override color for silhouette lines.
Alpha	The global opacity of the silhouette lines.
Cull Face	Backface culling for solid invisible mesh surfaces. For meshes with inverted normals values other than Back; Options are Back, Front or FrontAndBack.
(debug) Enable	Toggle the silhouette effect on/off.
(debug) Operation Number	Used internally to draw only the first N number of rendering operations inside the renderer.
