# Nitro Effect
The Nitro effect allows you to add lightning flashes to an image. Two scrolling textures are blended on top of one another and then filtered to achieve this effect.
# Effect Settings
- Blend mode: How the nitro effect is blended with the background. In HDR mode the option add can be used to get the best HDR glow effects.
- Write alpha: Enabling this option will make the background image transparent where there is no nitro effect overlayed.
- Albedo: The texture used to generate the nitro effect.
- Opacity mask: The opacity mask can be used to limit the effect to certain parts of the image.
- Bounds: This controls the width of the nitro effect. Increase the interval between these values to make the lines of the effect wider.
- Color start: The first color that is used for the nitro lines. This color is dominant where the effect is strongly visible.
- Color end: The second color that is used for the nitro lines. This color is dominant where the effect is just barely visible.
- Multiply: How strong the effect is visible.
- Scale: The size of the effect along the X and Y axes.
- Smoothness: You can use this to smoothen the lines of the effect.
- Speed: The scrolling speed of the texture used to generate the effect. X and Y are used for the first sample and Z and W are used for the second sample.
