General

The VRayLensEffects is a render effect plugin used to simulate bloom and glare lens effects by fitlering the rendered image with a filter kernel. It uses fast multithreaded technique to compute the result. You can add it from the V-Ray frame buffer.

Parameters

VRayStereoscopicBloom

On - turns on the bloom lens effect.

 

Mode - determines if the bloom will be applied to the RGB image, stored in a separate render element, or both. Storing to a render element only works with the V-Ray VFB.

 

Weight - specifies the strength of the interpolation between the filtered image and the original image.

 

Size - specifies the size of the filter as percentage of the image's width.

 

Shape - specifies the fall off of the filter.

 

Fill edges - enabling this option will add pixel data outside the edges of the original image. This will remove the darkening around the edges.

Glare

On - turns on the glare lens effect.

 

Mode - determines if the glare effect will be applied to the final image, stored into a separate render element, or both. Storing to a render element only works when the V-Ray VFB is enabled.

 

Glare type - this parameter specifies how the glare is computed. The possible values are:

 

From image - takes the image specified in Bitmap as filter kernel.

 

From render camera - takes the necessary parameters from the camera used to perform the rendeirng and automatically generates the filter kernel.

 

From camera parameters - takes the camera parameters specified in the VRayLensEffects render effect itself and automatically generates the filter kernel.

 

Fill edges - enabling this option will add pixel data outside the edges of the original image. This will remove the darkening around the edges.

 

Weight - specifies the strength of the interpolation between the filtered image and the original image.

 

Size - specifies the size of the filter as percentage of the image's width.

 

Bitmap - path to the filter kernel. Available if From Image option is selected. you can create filters using Filter generator which comes with V-Ray for 3ds Max instalation.

 

Turn on diffraction - this option will turn the diffraction on, producing colored patterns in the glare.

 

Use obstacle image - enable the use of the obstacle image specified in Obstacle.

 

Obstacle - path to the obstacle image. Available if Use obstacle image option is enabled.

 

Camera parameters

 

These parameters are used if the Glare type is specified as From camera parameters.

 

f-number - the f-number used to calculate the glare. Larger values produce smaller camera aperture and stronger glare effects.

 

Blades - this parameter controls if the camera aperture has any blades and how many they are. This effect directly controls the "rays" of the glare.

 

Blades rotation - this parameter controls the rotation of the of the camera aperture blades.
