Material SOP

Summary

The Material SOP allows the assignment of materials (MATs) to geometry at the SOP level.

Note: The Material parameter in Object Components will override material attributes assigned to geometry using the Material SOP.

materialSOP_Class

Parameters - Page

Material mat - Select a material to apply. Drag and drop a MAT to this parameter or enter the path to that MAT in the parameter field.

Info CHOP Channels

Extra Information for the Material SOP can be accessed via an Info CHOP.

Common SOP Info Channels

• num_points - Number of points in this SOP.

• num_prims - Number of primitives in this SOP.

• num_particles - Number of particles in this SOP.

• last_vbo_update_time - Time spent in another thread updating geometry data on the GPU from the SOP's CPU data. As it is part of another thread, this time is not part of the usual frame time.

• last_meta_vbo_update_time - Time spent in another thread updating meta surface geometry data (such as metaballs or nurbs) on the GPU from the SOP's CPU data. As it is part of another thread, this time is not part of the usual frame time.

Common Operator Info Channels

• total_cooks - Number of times the operator has cooked since the process started.

• cook_time - Duration of the last cook in milliseconds.

• cook_frame - Frame number when this operator was last cooked relative to the component timeline.

• cook_abs_frame - Frame number when this operator was last cooked relative to the absolute time.

• cook_start_time - Time in milliseconds at which the operator started cooking in the frame it was cooked.

• cook_end_time - Time in milliseconds at which the operator finished cooking in the frame it was cooked.

• cooked_this_frame - 1 if operator was cooked this frame.

• warnings - Number of warnings in this operator if any.

• errors - Number of errors in this operator if any.

An Operator Family that associates a shader with a SOP or Geometry Object for rendering textured and lit objects.

An Operator Family that reads, creates and modifies 3D polygons, curves, NURBS surfaces, spheres, meatballs and other 3D surface data.

The component types that are used to render 3D scenes: Geometry Component contain the 3D shapes to render, plus Camera, Light, Ambient Light, Null, Bone, Handle and other component types.

An Operator Family that associates a shader with a SOP or Geometry Object for rendering textured and lit objects.

An Operator Family which operate on Channels (a series of numbers) which are used for animation, audio, mathematics, simulation, logic, UI construction, and many other applications.

The Graphics Processing Unit. This is the high-speed, many-core processor of the graphics card/chip that takes geometry, images and data from the CPU and creates images and processed data.
