When V-Ray Lens Effects are used, a new channel called effectsResult will be created in V-Ray VFB. The RGB Channel button allows users to easily toggle between the effectsResult and original RGB channel.





Bloom/Glare Parameters

Image Removed

...

Bloom 

Image Added


Save – Save the current Bloom and Glare settings as a preset which can be loaded later.

Load – Loads a pre-saved Bloom and Glare preset.

Bloom/Glare effect Enables the V-Ray Lens Effects.

...

Threshold – Sets a minimum value for the rendered pixels to be considered as lens effects source. The Bloom/Glare effect will be generated only regarding pixels with larger value than the specified threshold.

Filter rotation – Rotates the final result effect, regardless of this is a filter image or a procedurally created one. 

Mode – Determines if the Bloom/Glare effect will be applied to the final image (in the effectsResult channel), stored into a separate render element, or both.

...

Saturation – When the value is set 0, the effects use the original hue of the bright pixels to create bloom and glare. Larger values intensify the hue set with the Cold/Warm option. See the Cold/Warm & Saturation examples below.

Blades – Sets custom camera aperture blades number to be considered for the lens effects. This parameter directly controls the number of "rays" of the glare.

Blades rotation – Controls the rotation of the camera aperture and blades.

Streak blur – Determines the width of the angle at which glare rays spread. The larger the value, the wider the spread. If set to 0, rays are directional; if set to 1, glare rays spread out and completely blend together. Observe in the Streak blur example below how values in-between change the glare rays appearance.

Use Obstacle Image – When enabled an obstacle image can be specified. Use it to simulate dirt and scratches on the camera lens. See how this changes the lens effects in the Obstacle Image example below.

Load Filter – Specifies the path to a filter kernel. You can create filters using the Filter generator tool which comes with the V-Ray for 3ds Max installation.

Hardware AcceleratedHardware Accelerated – Enable to calculate lens effects on the GPU. When multiple devices are present, V-Ray will prioritize the best one available.

Blades – Enables the Blades effect.

Sides – Sets custom camera aperture blades number to be considered for the lens effects. This parameter directly controls the number of "rays" of the glare.

Rotation  Controls the rotation of the camera aperture and blades.

Streak blur – Determines the width of the angle at which glare rays spread. The larger the value, the wider the spread. If set to 0, rays are directional; if set to 1, glare rays spread out and completely blend together. Observe in the Streak blur example below how values in-between change the glare rays appearance.

Peripheral grating – Enables grating along the sides of the aperture shape. 

Length – Controls the length of the grate lines.

Density – Controls the density of the grating effect in percent, where 100 is fully black.

Zoom – Controls the size of the halo around the lights.

Slope – Controls the direction of the lines.

Strength – Controls the strength of the blades effects.

Occlusion – When enabled it controls the aperture shape by occluding part of it.

Symmetric – Enables symmetric occlusion of the shape. When disabled, the occlusion appears only on one side of the shape.

Percent – Controls how much of the shape is occluded.

Rotation – Determines the position of the occlusion over the shape by rotation.

Arc – Controls the arc of the occlusion. A value of 0 sets a straight line, while a value of 100 makes an arc.

  • When using Deadline for network rendering in combination with V-Ray Lens Effects, make sure to disable the Local Rendering option when submitting to Deadline. Otherwise, Deadline is not able to save your bloom/glare effects.
