This section contains information on the Render Elements found in V-Ray for Modo.

Overview


Render elements present users with a way to break out renders into their component parts, such as diffuse color, reflections, shadows, mattes, etc. This gives precise control over the final image when using compositing or image editing applications to re-assemble the final image from these component elements. Render elements are also sometimes known as render passes.

Render elements generate at render time based on the elements selected by the user. Most render elements have parameters that can be set to customize the render element for its later use in compositing software. These parameters are described on each render element's individual page, along with common uses and any notes on their generation and usage.

V-Ray for Modo adds a number of render elements specifically for use with V-Ray. A list of render elements and their settings are found in the Render Elements panel which is accessed from the V-Ray Toolbox and pressing the RE button.

See the Render Elements Sub-groups section below for more information on the categories of render elements.

User Interface


 

 

 

Render element names – Controls the naming of the Render elements. Three options are given:

Modo – Names all elements according to the way Modo usually does.
V-Ray – Names all elements according to the way V-Ray usually does across any of V-Ray's application platforms.
Modo and V-ray – Names all elements with the Modo name appended with the V-Ray name.

Unfiltered Fragment Method – Determines which fragment to use for unfiltered render elements.

Best Coverage – For each pixel, the final values for the render element are taken from the object that has the largest contribution to that pixel.
Closest to Camera – For each pixel, the final values for the render element are taken from the object that is closest to the camera.

Deep output – When enabled, render elements are 32-bit images ready for use in a deep compositing workflow. When using, EXR needs to be the output type in the Final Color Output render element.

 

 Enabled or disable render elements by pressing the render element's name in the UI. Extra elements (such as V-Ray Light Select) can be accessed from Shader tree > Add Layer > V-Ray Render Elements.

 

 

 

Render Elements Sub-groups


Modo organizes its render elements into five major groups, to which V-Ray adheres:

 

Basic Render Elements

The Basic Render Elements generate data for the compositing process.
These include the Depth and Motion Vector render elements.

 

 

Geometry Render Elements

The Geometry Render Elements rely on geometric objects to generate geometry data useful in the compositing
process. These include the Geometric Normal, Bump Normals, Surface ID, World Coordinates, etc.

 

 

Lighting Render Elements

The Lighting Render Elements provide information on the lighting in a scene.
These include the Ambient Occlusion, Direct Illumination, Indirect Illumination, etc.

 

 

Material Render Elements

The Material Render Elements provide information on the materials in a scene.
These include the Diffuse, Reflection Coefficient, Roughness, and Transparent Color render elements.

 

 

Shading Render Elements

The Shading Render Elements provide information on the shaders in a scene.
These include the Luminous Shading, Reflection, Specular, Subsurface Shading, etc.
