Mattistic Flame parameter overview (OFX version)
The following list gives a basic description of the available parameters of the Mattistic Flame plugin for OpenFX hosts organized by category.
- Manage License: Opens a window to view the license status and activate a license (requires an internet connection).
- Use GPU if available: When enabled the plugin will try to use the graphics card to greatly accelerate rendering (requires CUDA or OpenCL).
- voxel resolution: Affects how many voxels are generated which determines how detailed the end result will be. Every step doubles the amount of voxels. Higher values lead to longer render times.
- samples/voxel: How many samples to take for every voxel a camera ray passes through. Increasing this can help reduce sampling artifacts.
- Mask: An external image input that is applied as a mask when compositing the render over the source.
- Fuel: An external image input of which the pixel values determine the height of the flames. The image is stretched to fit the bottom of the flame volume.
- step: A scaling factor for the speed of the animation.
- offset: An offset in frames for the starting point of the animation.
- location: The world location of the camera.
- rotation: The world rotation of the camera.
- rot. order: The order in which the rotation around the X, Y & Z axes are applied.
- focal length: The focal length of the camera in mm. This determines the field of view in combination with the sensor size.
- sensor size hor.: The horizontal size of the sensor in mm.
- sensor size ver.: The vertical size of the sensor in mm.
- sensor fit: Determines how the image aspect ratio is fitted to the sensor aspect ratio.
- motion blur: The amount of directional blur applied to fast movement. This is not true motion blur but an approximation applied as a 2D effect.
- exposure: A scaling factor for the brightness of the rendered image.
- white balance: The temperature in K that is considered white. Higher values add more red/orange tones to the image while lower values add more blue.
- key loc.: The world location of the light source. This is a point light without any falloff over distance.
- key color: The color of the key light source.
- key scale: A scaling factor for the amount of light that is emitted by the key light source.
- color: The color of the smoke when illuminated by a white light.
- absorption: A scaling factor for how quickly light is absorbed by the smoke as it shines through it.
- density: Scales the density of the smoke. This also impacts the brightness of the flames as some smoke is needed for the flames to be visible.
- heat: Scales the temperature of the fire. This influences both the brightness and the color of the flames. The actual brightness also depends on the smoke density and fire brightness parameters.
- brightness: Scales the brightness of the fire. The actual brightness also depends on the smoke density and fire heat parameters.
- highlight sat.: The amount by which high values in the rendered image are desaturated.
- blue core: How visible the blue part of the flame is. Not influenced by the smoke density parameter.
- transition: The exponent of the transition towards the surface of the flame. Higher values lead to thinner flame surfaces.
- dissipation: The exponent of the transition away from the surface of the flame. Higher values lead to thinner flame surfaces.
- scale: World scale of the volume.
- offset: World offset of the volume.
- dimensions: World dimensions of the volume before scaling.
- rotation: World rotation of the volume around an upward pointing axis.
- wind: Mimics a wind effect displacing the flames as they rise. The strength is set independently along the X, Y & Z axes.
- random seed: An initial value for the random number generator used to generate the turbulence and fuel variation.
- turb. scale: The scale of the turbulence. A higher value will create smaller details making the flames appear larger.
- turb. strength: The amount by which the turbulence effect is applied to the flames.
- fuel multiplier: A scaling factor for the fuel source.
- fuel variation: The amount by which a noise pattern is applied to the fuel. Can be used to separate a uniform fuel source into smaller individual flames.
