![]() If the this value is more than 100, some cells will start getting skipped and artifacts may appear. As the GPU Preview traces rays through the simulator, this value controls how often to get information from the grid. ![]() Step Size as % of Cell Size – Specifies the ray marching step as a percentage of the cell size. Gamma – Specifies the gamma for the GPU Preview. Smoke Constant Color – This color is used for shading of the smoke with the GPU Preview. Simple Smoke Opacity –This value is used as opacity multiplier - the higher it is, the denser the smoke will look. This angle rotates the light horizontally around the container and it can go from 0 to 360 degrees. Light Azimuth – The GPU Preview is lit by one single directional light. 0 degrees places the light right above the container. This angle means the height of the directional light above the horizon. Light Inclination – The GPU Preview is lit by one single directional light. Note that all particles are drawn with the same size.Įnable – Enables the GPU shading preview in the viewport. Particle Size – Sets the size of the particles in the preview window. Particles with a Scale Color Bychannel value higher than the specified Scale Max are also pure white. You can also find more info about the usual particle channel maximum values on the Particle Channel Ranges page.Īuto Scale – When enabled, automatically calculates Scale Max based on the Min/Max range of the selected Scale Color By particle channel, assuming the respective channel export has been enabled in the Output rollout for the selected particle system. Scale Max – When Auto Scale is disabled, allows you to specify a constant value at which the particle preview color becomes pure white. The preview is only affected by the Scale Max option if the particle system has the Viscosity channel export enabled. Viscosity – The higher the viscosity the particles, the whiter they will appear.The preview is only affected by the Scale Max option if the particle system has the Age channel export enabled. Age – The older the particles are, the whiter they will appear.The preview is only affected by the Scale Max option if the particle system has the Size channel export enabled. Size – The larger the particles are, the whiter they will appear.The preview is only affected by the Scale Max option if the particle system has the Velocity channel export enabled. Speed – The faster the particles move, the whiter they will appear.No Scaling – All particles will be the same color - the one specified by Preview Color.Scale Color By – Specifies the particle channel used for adjusting the particle preview color. Note that if the particle system has an RGB channel exported, it will be used in place of the Preview Color. Moving particles are displayed as a blend between their default color and white, based on the selected Scale Color By channel. Preview Color – Specifies the default color of the particles. Show system – When enabled, the particle system will be visible in the simulator preview. The controls below affect the visualization of the currently selected particle group. Auto Range – When enabled, automatically adjusts the preview ranges of visible channels for the current frame so that important data is always visible and the preview is always quick.Įnable – Enables the preview of particles. RGB – Enables the representation of the RGB channel. Viscosity - Enables the representation of the viscosity channel. Streamlines Length – Signifies the maximum length of each streamline in the preview. Adjusting the value will provide you with a guide/preview of the velocity field's motion. The Line's length is measured in voxels and at the lowest setting, the Streamlines will be no larger than a voxel. Rainbow Color Curve – Represents the Velocity Streamlines in rainbow colors. Velocity Streamlines – T races the velocity field of the cache files to generate a streamline preview. Velocity – Enables the representation of the velocity. Smoke – Enables the representation of the smoke.įuel – Enables the representation of the fuel. Temperature – Enables the representation of the temperature.Īs fire – When enabled, the natural color of a hot black body is used for coloring the temperature. Only The Overlap Of – When enabled, all channels in a cell must meet the selected threshold conditions to visualize the cell. All enabled channels are drawn if their content is between the corresponding thresholds. The default preview mode that displays the individual content of each cell.
