When this option is enabled, the linear distance of the Lens Effect is recorded, and can be used in special effects that make use of the Z-Buffer.Īllows distance from the camera or viewport to affect the size and/or the intensity of the effect. The Z-Buffer is useful for optical effects. Stores an object's distance from the camera. If you are not rendering to a 32-bit file, do not enable this option. If you want to composite a Lens Effect, or an image that contains a Lens Effect, over the top of another image, enable this option. Alpha channels are used to composite one image seamlessly over the top of another. The alpha channel is an extra 8 bits of color (256 colors) that indicate transparency in an image. Specifies whether or not the Lens Effect affects the alpha channel of an image when the image is rendered in a 32-bit file format. The value is a percentage of the size of the flare. Positive values stretch the effect horizontally, and negative values stretch it vertically. Squeezes the size of the overall Lens Effect, either horizontally or vertically to compensate for different frame aspect ratios. For example, if you set up a Ray effect, you will get slightly different rays in the lens flare if you adjust the seed value.Īffects the amount that the Lens Effect rotates from its default position, as the position of the effect changes relative to the camera. Using Seed guarantees a different Lens Effect, even if the differences are very small. Gives the random number generator in Lens Effects a different starting point, which creates a slightly different Lens Effect without changing any settings. Higher values produce a bright, more opaque effect, and lower values produces a dim, transparent effect. This value is a percentage of the size of the rendered frame.Ĭontrols the overall brightness and opacity of the Lens Effect. The LZV file format doesn’t save the animation keys of an animated parameter.Īffects the size of the overall Lens Effect. Note: Saving an effect as an LZV file will only save the attributes of the effect on the frame that it is saved at.
