Run External Program Procedural VOP node

program

This procedural will run an external application in order to generate geometry at render time. The name of the program to run must be specified. Alternatively, a second program string can be specified to generate motion blurred geometry.

Before the program is run, the program string is scanned for the sub-string '%LOD'. All occurrences of this sub-string are replaced with the level of detail computed by mantra (a floating point number representing the screen space.

Parameters

Program - The program to run to generate geometry. For

Blur - The program to run in order to generate geometry

Shutter - Optionally, a shutter time can be specified

Note

This procedural requires a bounding box to be specified.

When generating motion blurred geometry, the bounds must enclose the blurred geometry as well.
