Curves and points will be oriented so that their normals point in the direction of the orient vector attribute. The following attributes on geometry control how mantra renders the geometry. This command is run one time, after all IFDs have been generated. This command is run after each IFD is generated.Īlthough the IFD may have been generated, this does not necessarily mean that mantra has finished rendering the image when this command is run. This command is run before each IFD is generated. This command is run before any IFDs are generated.

The command checks the parameters of the output driver when it is rendering a range or sending output to a command.īefore the render occurs, Houdini will automatically set the current hscript directory to point to the output driver. The commands are always run when rendering occurs. It is possible to use the python, unix or source hscript commands to perform complex processing. The resulting string will be run as an hscript command. See the documentation for these options below.Įach script command refers to an hscript command which will be run, regardless of the expression language selected for the parameter. The Pixel samples and ray sample controls are good places to start. Turn on motion blur for all objects (Properties tab,Sampling sub-tab, Allow motion blur).Īdjust render quality (Properties tab, Sampling sub-tab). The frame range to render for an animation (Valid frame range and Start/end/inc). This will not save the image to disk, but you can save manually from MPlay. Use ip instead of a filename to render directly into theMPlay image viewer (this is the default). (Properties tab, Output sub-tab, Output picture). The camera to render from (Main tab, Camera). Some important parameters on the render driver include:

For more information on adding properties to a node see the Edit Parameter Interface.įor complex scenes involving multiple render passes, separate lighting and shadow passes, and so on, you can set up dependency relationships between render drivers by connecting driver nodes together. For more information on properties, see properties.
Select a render node, and in the parameter editor click the Gear menu and choose _Edit rendering parameters to edit the properties on the node. If you add object properties to the render driver, they define defaults for all objects in the scene. You can add and remove properties from the output driver just like you can for objects. To see the actual network of render driver nodes, click the path at the top of a network editor pane and choose Other networks > out. You can edit an existing render node with Render > Edit render node > node name.
You can create a new mantra node by choosing Render > Create render node > Mantrafrom the main menus. The mantra output driver node uses mantra (Houdini’s built-in renderer) to render your scene. Renders the scene using Houdini’s standard mantra renderer and generates IFD files.
