7.2 Procedures Related To MEL Script Attributes

global proc DL_userPreRenderMel (string $render_pass)

This procedure is called right before the Pre Render Mel script of the render pass being rendered is executed.

global proc DL_userPostRenderMel (string $render_pass)

This procedure is called right before the Post Render Mel script of the render pass being rendered is executed.

global proc DL_userPreFrameMel (string $render_pass)

This procedure is called right before the Pre Frame Mel script of the render pass being rendered is executed.

global proc DL_userPostFrameMel (string $render_pass)

This procedure is called right before the Post Frame Mel script of the render pass being rendered is executed.

global proc DL_userPostOptionMel (string $render_pass)

This procedure is called right before the Post Option Mel script of the render pass being rendered is executed.

global proc DL_userPreWorldMel (string $render_pass)

This procedure is called right before the Pre World Mel script of the render pass being rendered is executed.

global proc DL_userPostWorldMel (string $render_pass)

This procedure is called right before the Post World Mel script of the render pass being rendered is executed.

global proc DL_userPreGeoMel (string $render_pass, string $geometry_name, string $visible_lights[], int $is_shadow, string $geo_attrib_nodes[])

This procedure is called right before the Pre Geo Mel script attribute of related geometry attribute nodes is called. The parameters passed to this procedure are:

` string $render_pass'

The render pass node name

` string $geometry_name'

The name of the geometric object about to be output

` string $visible_lights[]'

The list of renderable, visible light shapes.

` int $is_shadow'

This parameter is set to `1' when this procedure is called during a shadow map rendering. It is set to `0' when called during a regular frame rendering. It can also be set to `-1' when it is called outside of a Frame Begin / End block. Currently this can only happen when outputting geometry instances connected to a particle instancer.

` string $geo_attrib_nodes[]'

The list of geometry attribute nodes that are either connected or inherited by the current object.

global proc DL_userPostGeoMel (string $render_pass, string $geometry_name, string $visible_lights[], int $is_shadow, string $geo_attrib_nodes[])

This procedure is called right before the Post Geo Mel script attribute of related geometry attribute nodes is called. The parameter list is identical to DL_userPreGeoMel.

global proc DL_userLightPreRenderMel (string $render_pass, string $light_name, string $light_attribs_nodes[])

This procedure is called just before the Pre Render MEL script defined in light attribs node attached to the light source shape. The parameters passed to this procedure are:

` string $render_pass'

The render pass node name

` string $light_name'

The light source shape name

` string $light_attribs_nodes[]'

The list of light attributes nodes attached to the light source shape.

global proc DL_userLightPostRenderMel (string $render_pass, string $light_name, string $light_attribs_nodes[])

This procedure is called just before the Post Render MEL script defined in light attribs node attached to the light source shape. The parameters list is identical to DL_userLightPreRenderMel.
