+ | ====== Fan - VFX ====== | ||
+ | This section details the properties of the Fan object for SpeedTree Cinema. | ||
+ | |||
+ | The direction and strength of the wind are indicated in the upper right corner of the [[tree_window|Tree Window]]. | ||
+ | |||
+ | =====Main===== | ||
+ | The properties in this group control wind quality and the enabled state. | ||
+ | |||
+ | ==Wind wizard...== | ||
+ | Press the button to launch the Wind Wizard. | ||
+ | |||
+ | ==Enabled== | ||
+ | Use this property to toggle wind on and off in the [[tree_window|Tree Window]]. | ||
+ | |||
+ | ==Quality== | ||
+ | Controls the quality of the oscillation computations. | ||
+ | |||
+ | =====Settings===== | ||
+ | The properties in this group control high level wind settings. | ||
+ | |||
+ | ==Strength== | ||
+ | This property sets the strength of the wind. 0.0 corresponds to no wind, 1.0 corresponds to the highest wind. | ||
+ | |||
+ | > | ||
+ | |||
+ | ====Response Times==== | ||
+ | These properties control how quickly the model responds to changes in wind strength and direction. | ||
+ | |||
+ | ==Strength== | ||
+ | Sets the response time for strength changes. | ||
+ | |||
+ | ==Direction== | ||
+ | Sets the response time for direction changes. | ||
+ | |||
+ | ===== VFX Branch Motion ===== | ||
+ | The properties in this group control branch motion. | ||
+ | |||
+ | {{ :: | ||
+ | |||
+ | > | ||
+ | |||
+ | ====Scalars==== | ||
+ | These values scale the corresponding affect by the value entered for each of the five branch wind groups. | ||
+ | |||
+ | ====Shared==== | ||
+ | The properties in this group affect the entire model, essentially making it sway in the wind. This is typically the slowest moving group and uses small values for bend and turbulence. | ||
+ | |||
+ | ==Bend== | ||
+ | This property controls how much the whole model will bend in the direction of the wind across all wind conditions. | ||
+ | |||
+ | ==Turbulence== | ||
+ | This property controls how much (the amount, not the speed) the whole model will oscillate around its bent over position as specified by " | ||
+ | |||
+ | ==Frequency== | ||
+ | This property controls how fast the whole model will oscillate. | ||
+ | |||
+ | ==Twist== | ||
+ | This property controls how much the model twists around the global up vector. | ||
+ | |||
+ | ==Start== | ||
+ | This property designates the percentage up the tree where the " | ||
+ | |||
+ | ====Levels 1, 2, 3, and 4==== | ||
+ | The properties in this group apply to geometry with the associated [[windvfx# | ||
+ | |||
+ | ==Bend== | ||
+ | This property controls how much the longest branch at this level will bend in the direction of the wind across all wind conditions. | ||
+ | |||
+ | ==Turbulence== | ||
+ | This property controls how much (the amount, not the speed) the longest branch at this level will oscillate around its bent over position as specified by " | ||
+ | |||
+ | ==Frequency== | ||
+ | This property controls how fast the branches at this level oscillate. | ||
+ | |||
+ | ==Flexibility== | ||
+ | This property control how much ripple will be seen during branch movement. | ||
+ | |||
+ | ==Independence== | ||
+ | This value controls how synchronized branch motion appears. | ||
+ | |||
+ | ==Disable== | ||
+ | Check this box to disable all wind at this level. | ||
+ | |||
+ | ===== VFX Leaf Motion ===== | ||
+ | The properties in this group control leaf motion. | ||
+ | |||
+ | Leaves are assigned a group by one of their wind properties ([[batchedleaf_generator# | ||
+ | |||
+ | > | ||
+ | |||
+ | ====Scalars==== | ||
+ | These values scale the corresponding affect by the value entered for each of the two leaf wind groups. | ||
+ | |||
+ | ====Groups 1 & 2==== | ||
+ | These are the properties than control wind behavior for each group. | ||
+ | |||
+ | ==Bend== | ||
+ | This property controls how much the leaves will bend into the wind. | ||
+ | |||
+ | ===Turbulence=== | ||
+ | These properties control how much the leaves will oscillate around the position determined by the " | ||
+ | |||
+ | ==Frequency== | ||
+ | Controls how fast the leaves will oscillate. | ||
+ | |||
+ | ==Amount== | ||
+ | Sets the maximum amount of rotation for each oscillation. | ||
+ | |||
+ | ==Independence== | ||
+ | This value controls how synchronized leaf motion appears. | ||
+ | |||
+ | ===Flutter=== | ||
+ | The properties in the group control random rotations that are not based on wind direction. | ||
+ | |||
+ | ==Frequency== | ||
+ | Controls how fast the leaves will oscillate. | ||
+ | |||
+ | ==Amount== | ||
+ | Sets the maximum amount of rotation for each oscillation. | ||
+ | |||
+ | ===== VFX Frond Motion ===== | ||
+ | The properties in this group control frond wind animation. | ||
+ | |||
+ | ====Group 1==== | ||
+ | Fronds are constructed along " | ||
+ | |||
+ | > | ||
+ | |||
+ | ==Bend== | ||
+ | This property controls how much the fronds will bend into the wind. | ||
+ | |||
+ | ===Turbulence=== | ||
+ | These properties control how much the fronds will oscillate around the position determined by the " | ||
+ | |||
+ | ==Frequency== | ||
+ | Controls how fast the fronds will oscillate. | ||
+ | |||
+ | ==Amount== | ||
+ | Sets the maximum amount of rotation for each oscillation. | ||
+ | |||
+ | ==Independence== | ||
+ | This value controls how synchronized frond motion appears. | ||
+ | |||
+ | ==Ripple== | ||
+ | This value controls how much ripple is allowed on individual frond. | ||
+ | |||
+ | =====Gusting===== | ||
+ | The properties in this group control the timing and strength of random wind [[windvfx# | ||
+ | |||
+ | ==Enabled== | ||
+ | Toggles gusting on and off. | ||
+ | |||
+ | ==Frequency== | ||
+ | Controls how often gusts can occur. | ||
+ | |||
+ | ==Strength== | ||
+ | Controls how much additional wind strength is added to the nominal wind strength during a gust. Add variance to make each gust random. | ||
+ | |||
+ | ==Duration== | ||
+ | When a gust happens, this value controls how long it will remain active (in seconds). Use the variance to make each gust length random. | ||
+ | |||
+ | ====Response Scalars==== | ||
+ | |||
+ | ==Rise== | ||
+ | This value scales how long it takes for a gust to reach its maximum value. Lower this value to increase the speed at which gusts impact the model. | ||
+ | |||
+ | ==Fall== | ||
+ | This value scales how long it takes for a gust to return to the nominal wind level. Lower this value to increase the speed at which the model returns to nominal wind conditions after a gust. | ||
