This addon adds 4 CompositorEffects that can be added to cameras. These shaders take the color output of the camera and uses it to adjust their images. This creates an image that can only be seen while its playing.
All you have to do is add one of the three effects (CyclingNoiseEffect, SlidingNoiseEffect, VariableSlidingNoiseEffect, or ColorfulNoiseEffect) to your camera's compositor effects. To make the effect good, the scene's setup needs to work well with the shader. In the first person demo, I give the player camera an OmniLight3D, which makes closer objects brighter. I also recommend making the sky black, so it doesn't interfere with the noise.
This effect cycles through different shades of white and black to create a cycling image. The brighter the input pixel, the faster the shader updates.
- steps is how many different shades the effect displays
- speed is how fast the effect is updated
This effect moves pixels every frame to create a sliding effect. All moving pixels move at the same exact speed.
- direction is the direction the pixels slide
- invert controls which part of the image slides
- frames_per_update controls how often the sliding updates
Very similar to the other sliding noise effect, but brighter pixels move faster. Darker pixels will slide at a lower framerate, which conveys depth
- direction is the direction the pixels slide
- frames_per_update controls how often the sliding updates
- speed_steps is how many different speeds the noise can slide
- brightness_exponent controls at what distances the speeds are
Equivalent to the cycling noise, but can cycle color too. The red channel controls pixel value, and the green channel controls color.
- value_steps is how many different brightness levels the effect displays
- value_speed is how fast the value of the pixels change
- hue_steps is how many different colors the effect displays
- hue_speed is how fast the colors of the pixels change
- hue_offset adjusts what colors are displayed
