This page provides information on the Filter Render Elements in V-Ray for Unreal. 

Page Contents ×

Overview


The Filters Render Elements show only the selected set of channels in the render, disregarding any backgrounds, textures, etc.

 

 

 

Parameters


Enable – Enables the rendering of the channels included in this group.

The Filters Render Elements share the same Channel options:

Active – Enables the render of the channel.

Denoise – Enables the render element's denoising, provided the Denoiser render element is present.

Consider for AA – By default, the Image sampler applies AA based on the RGB image. When this option is enabled, the Render Element is considered for AA.

Filtering – When enabled, it applies the antialiasing filter to the render element.

Color Mapping – Applies the default color mapping options to this render element (Reinhard). 

 

 

Diffuse Filter


The Diffuse Filter Render Element shows the colors and textures used in materials, flatly applied to objects with no lighting information. The colors are the actual colors set in the material definition, and each texture appears as it does in the texture (file) itself. There are no highlights or shadows, and any background image is not included.

 

 

 

 

Reflection Filter


 The Reflection Filter Render Element stores reflection information calculated from the materials' reflection values in the scene. Surfaces with no reflection values set in its material(s) will contain no information in the render pass and will therefore render as black.

 

 

 

Refraction Filter


The Refraction Filter Render Element is an image that stores refraction information calculated from the materials' refraction values in the scene. Materials with no refraction values appear as black, while refractive materials appear as white (maximum refraction) or gray (lesser amounts of refraction). If any hue (color) is specified in the material's Refractive Color parameter, that hue and value will be represented here in the Refraction Filter as well as being affected by the refraction's Amount parameter.

 

 

 

Shadows


The Shadows Render Element works as a reverse mask for shadows. It is a color image that can be used to lighten, darken or tint shadows. Shadows can be lightened in the composite by adding this render element, or darkened by subtracting this render pass from the final composite.

 

 

Atmosphere


The Atmosphere Render Element stores only atmospheric or volumetric participating media such as fog. This render element can then be used to enhance or color-correct just the atmospheric component of the image during the compositing process.
