+ | |||
+ | ===== Generation ===== | ||
+ | The generation properties are described in full detail under [[generation_properties|Generation Properties]]. | ||
+ | |||
+ | ===== Random Seeds ===== | ||
+ | Properties that have [[toolvariance_editor|variance]] are given random values based on a seed value in this group. | ||
+ | |||
+ | == Randomize All == | ||
+ | Randomizes the value for all seeds used to compute this generator. | ||
+ | |||
+ | ===== Materials ===== | ||
+ | The properties in this group control the material assignments and mesh resolution. | ||
+ | |||
+ | ==== Frond ==== | ||
+ | Applies a [[kcmaterialspbr|material]] to the frond mesh in this generator. Use the button controls to add [+] or remove [-] materials per geometry type. | ||
+ | |||
+ | > | ||
+ | |||
+ | == Material == | ||
+ | Specify a named material from the [[kcmaterialsassetsbar|Materials Asset bar]], or use a material set from the [[toolmaterial_sets|Material Sets Bar]]. | ||
+ | |||
+ | == Weight == | ||
+ | Sets the probability that a node will receive this material index (this weight ÷ the sum of all weights). | ||
+ | |||
+ | ==Flip== | ||
+ | When enabled, randomly selected frond nodes are flipped over the Y-axis. | ||
+ | |||
+ | ==Two-Sided== | ||
+ | When enabled, the frond mesh geometry is duplicated for the reverse side. If you are looking to reverse the material and not the geometry, check the two-sided box in the material assets bar instead. | ||
+ | |||
+ | > | ||
+ | |||
+ | ====Mesh==== | ||
+ | |||
+ | == Index == | ||
+ | When set to a value other than 0, the mesh currently assigned will go up or down in mesh resolution (" | ||
+ | |||
+ | > | ||
+ | |||
+ | == Resolution == | ||
+ | This curve sets which mesh version (" | ||
+ | |||
+ | =====Shape===== | ||
+ | The properties in this group control how the mesh is manipulated when computing the frond. | ||
+ | |||
+ | == Unification == | ||
+ | This property lets you maximize the number of outward facing frond meshes. Parent spine rotations can often cause the frond mesh to face inward. With unification enabled, the initial orientation of frond meshes will be adjusted so that they face out relative to the selected anchor position. | ||
+ | |||
+ | ^Global|The anchor point is located where the node's highest ancestor hits the ground.| | ||
+ | ^Deep|The anchor point is the base of a node very near (and sometimes exactly on) the root of the node's ancestors.| | ||
+ | ^Intermediate|The anchor point is somewhere in the middle of the node's ancestors.| | ||
+ | ^Local|The anchor point is very near where the node is attached.| | ||
+ | ^None|No anchor point is computed, and no unification is done.| | ||
+ | |||
+ | == Gravity == | ||
+ | Pulls the edges of both sides of the Frond Mesh toward the ground. A negative value will pull the edges of the frond up towards the sky. | ||
+ | |||
+ | ==Fold== | ||
+ | Folds each side of the frond toward each other (Much like folding a piece of paper). | ||
+ | |||
+ | ==Curl== | ||
+ | Curls both of the outside mesh edges in towards the spine. | ||
+ | |||
+ | ==Roll== | ||
+ | Rotates the mesh around the parent spine. | ||
+ | |||
+ | ====Boundary==== | ||
+ | The properties in this group control where the frond starts and stops on its parent. | ||
+ | |||
+ | ==Start== | ||
+ | Controls where the frond begins on the spine (0.0 corresponds to the beginning; 1.0 corresponds to the end). | ||
+ | |||
+ | ==End== | ||
+ | Controls where the frond ends on the spine (0.0 corresponds to the beginning; 1.0 corresponds to the end). | ||
+ | |||
+ | ====Left-Right Variance==== | ||
+ | The properties in this group control how much the left and right sides of the frond differ in their deformation. | ||
+ | |||
+ | ==Amount== | ||
+ | Adding this variance amount causes the two sides of a mesh to react independently to the amount of " | ||
+ | |||
+ | ==Seed== | ||
+ | Vary this value to change how the variance is computed. | ||
+ | |||
+ | ====Scale==== | ||
+ | The properties in this group scale the width and height of the mesh. The length is always controlled by the parent spine. | ||
+ | |||
+ | ==Width== | ||
+ | Scales the width of the mesh. This scale corresponds to the X-axis of the mesh asset. | ||
+ | |||
+ | ==Height== | ||
+ | Scales the height of the mesh. This scale corresponds to the Z-axis of the mesh asset. | ||
+ | |||
+ | ===== Lighting ===== | ||
+ | The properties in this group modify the vertex normals to change the lighting behavior of the frond. | ||
+ | |||
+ | ==Alignment== | ||
+ | This value causes the vertex normals to point in the direction of the parent spine' | ||
+ | |||
+ | ==Spread== | ||
+ | This value causes the vertex normals to point away from the parent spine. | ||
+ | |||
+ | =====Segments===== | ||
+ | The properties in this group control polygonal resolution when no mesh is assigned to the frond material. | ||
+ | |||
+ | ==Accuracy== | ||
+ | Sets the number of segments in each rib of the frond infrastructure. | ||
+ | |||
+ | > | ||
+ | |||
+ | ====Width==== | ||
+ | The properties in this group combine to set the number of width segments. | ||
+ | |||
+ | ==Absolute== | ||
+ | The minimum number of segments across the frond. | ||
+ | |||
+ | ==+ Relative== | ||
+ | Segments are added to the " | ||
+ | |||
+ | > | ||
+ | |||
+ | ===== Season ===== | ||
+ | The properties in this group provide the mechanism by which assigned materials can change with the [[kcseasons|Seasons]] slider. | ||
+ | |||
+ | == Start Offset == | ||
+ | Determines when the branch will start to transition. The default value of 0.0 means it will start immediately (higher values delay the start, lower values make it start sooner). | ||
+ | |||
+ | == Time Scale == | ||
+ | Controls how long it will take to complete its transition. The default value of 1.0 means one year. | ||
+ | |||
+ | ===== Collision ===== | ||
+ | The properties in this group influence how fronds in this generator interact with the [[toolcollision|collision]] system. | ||
+ | |||
+ | == Style == | ||
+ | Use this property to set how the fronds behave during collision computations from the following options: | ||
+ | |||
+ | ^Everything | Fronds in this generator collide with each other and all other leaves.| | ||
+ | ^Ignore Siblings | Fronds in this generator ignore siblings but collide with everything else.| | ||
+ | ^Knock out Others Only | Fronds in this generator cannot be removed, but they can eliminate leaves in other generators.| | ||
+ | ^Nothing |These fronds do not participate in collision computations.| | ||
+ | |||
+ | == Weight == | ||
+ | When fronds collide, the one with the higher weight wins. Use this property to set the weight. | ||
+ | |||
+ | == Pivot Threshold == | ||
+ | Sets how far away from the pivot (as a percentage of size) a collision has to happen in order to count. | ||
+ | |||
+ | ===== Wind ===== | ||
+ | The properties in this group influence how fronds are animated in wind simulations. | ||
+ | |||
+ | ==Amount== | ||
+ | Scales how much the frond moves during wind simulations. | ||
+ | |||
+ | ==Cross== | ||
+ | Influences the amount of motion as the frond grows from the parent spine to the edge. | ||
+ | |||
+ | |||
+ | ===== Growth ===== | ||
+ | The properties in this group control how the model behaves during animated growth. | ||
+ | |||
+ | == Speed Scale == | ||
+ | The speed at which a frond will grow is set on the [[tooltimeline|Timeline Bar]]. Use this property to scale that value. The profile curve scales the speed relative to the fronds' | ||
+ | |||
+ | ==== Transitions==== | ||

+ | Adds additional gravity to the frond at the start of the growth. | ||

+ | Increases or decreases the likelihood that fronds in this generator will survive the LOD process (vs. fronds in other generators). | ||
+ | |||
+ | ==Mesh== | ||
+ | Controls which [[kcmeshes# | ||
+ | |||

+ | |||
+ | > | ||
+ | |||

+ | |||
+ | ==Style== | ||
+ | This property controls how the red portion of the color is computed from the following options: | ||
+ | |||
+ | ^Set | Sets the color directly using the " | ||
+ | ^Offset from parent | The " | ||

+ | |||
+ | ==Style== | ||
+ | This property controls how mesh asset vertex colors are used from the following options: | ||
+ | |||
+ | ^Interpolate | The " | ||
+ | ^Add | The " | ||
+ | |||
+ | ==Contribution== | ||
+ | This value sets how much influence the mesh asset vertex color has on the final vertex color. | ||
+ | |||
+ | ===== Lightmap ===== | ||
+ | Lightmap UVs are computed for several versions of the Modeler designed for use with game engines. | ||
+ | |||
+ | == Weight == | ||
+ | Influences how much space in the lightmap fronds made by this generator can have. | ||
