![]() ![]() Percent – Controls how much of the shape is occluded. When disabled, the occlusion appears only on one side of the shape. Symmetric – Enables symmetric occlusion of the shape. Occlusion – When enabled it controls the aperture shape by occluding part of it. Strength – Controls the strength of the blades effects. Slope – Controls the direction of the lines. Zoom – Controls the size of the halo around the lights. Length – Controls the length of the grate lines. Peripheral grating – Enables grating along the sides of the aperture shape.ĭensity – Controls the density of the grating effect in percent, where 100 is fully black. Observe in the Streak blur example below how values in-between change the glare rays appearance. If set to 0, rays are directional if set to 1, glare rays spread out and completely blend together. The larger the value, the wider the spread. Streak blur – Determines the width of the angle at which glare rays spread. This parameter directly controls the number of "rays" of the glare.īlades rotation – Controls the rotation of the camera aperture and blades. Sides – Sets custom camera aperture blades number to be considered for the lens effects. Otherwise, the lens effects are applied to the RGB channel instead.Ĭlicking the button displays a short menu that resets all the parameters for a lens effect to their default values. Otherwise, a default intensity of 1.0 is saved, so that it can be adjusted via post-processing.Ĭreate effectsResult channel – When enabled, it generates an effectsResult channel without needing the Denoiser render element to be active. Save Glare channel – When enabled, it writes the glare channel to a file when writing all channels.īake intensity – When enabled, the intensity is baked in the Glare channel. Update – Manually forces the recalculation of the bloom/glare effects. Interactive – When enabled, the bloom/glare effect will be automatically recalculated and applied after any V-Ray lens effects parameter change. See the Cold/Warm & Saturation examples below. The hue shift requires Saturation values larger than 0. When disabled, the effects will receive warm hue. When multiple devices are present, V-Ray will prioritize the best one available.Ĭold/Warm – When enabled, the Bloom/Glare effect will be toned to cold hues. Hardware Accelerated – Enable to calculate lens effects on the GPU. Larger values intensify the hue set with the Cold/Warm option. ![]() Saturation – When the value is set 0, the effects use the original hue of the bright pixels to create bloom and glare. Rotation – Rotates the final result effect, regardless of this is a filter image or a procedurally created one. ![]() The Bloom/Glare effect will be generated only regarding pixels with larger value than the specified threshold. Threshold – Sets a minimum value for the rendered pixels to be considered as lens effects source. Values in-between blend the two effects proportionally. A value of 0 removes the bloom completely and applies only glare. A value of 1 forces bloom to be applied to full extent and without any glare. See the Intensity example below.īloom – Controls the blend between bloom and glare. Values lower than 1 can be used to produce subtle bloom/glare from overbright sources. Increasing the value can boost the effect by simulating up to 20 times brighter source. Intensity – Multiplier for the bloom/glare source bright pixels. Size – Specifies the size of the filter as percentage of the image's diagonal. Enable bloom/glare effect – Enables the V-Ray Lens Effects.
