Build Options
Build Dist R
Sets how far from their final destination the element will start their animation. This value can either be a single value used for all elements or by clicking the right hand down arrow you can choose to use random values between two values to add variation if required.
Origin
This is the point the elements move towards and controls the direction of the movement. Changing this value will control say whether the object builds from the front, or from behind or above etc. You can also use the editor tool to drag the origin directly in the scene view, and like other params this can be overridden per object etc. so different parts of the object can build from different directions.
Projection
This is an important value to help control the build direction of the elements. For example if you wanted all the parts to drop straight down you would set this to 0 1 0 so that only the y part of the direction is used. If you wanted sideways movement you would use 1 0 0. You can set these top any value to remove or amplify the direction value, or negate if if needed.
Build Style
Various options for how the elements will animate to their destinations. Note this like other values can be overridden per object or using the Adjust system.
None - No animation will happen
Appear - The element will just appear at its destination
Radial - This and vertical currently do the same thing. The starting point for the element will be on the line from the Origin through the elements final position and at a distance of the Build Distance. Adjust the origin and projection value will control the direction of the movement.
Vertical - This is the same as the Radial option and uses the origin position and project value to control the animation direction.
Transform - If you use the Spline option then use this mode to make use of the spline either to move along or to build from.
Use Place Curve
By default elements will animate to their end position in a linear way which can be a little dull so there is an option to use various curves to control the behaviour of the element as it moves into position. The place curve will control the position along the path to its position with 0 being the start point and 1 being the final end point, so you could add a bounce by doing a simple place curve that reaches 1 early and then reduces before going back to 1 like in the example below. You can off course have multiple bounces, change the amount of bounce or generally control the speed of the placement animation in way.
To enable the use of the place curve you need to check the box to the left of the curve that will then enable the curve and allow you to edit the curve.
Place Curve
The curve to use for placing the elements.
Use Rot Curve
You can also use a curve to control any rotation that is applied to the element as it positions itself.
Place Rot Curve
The curve used to control the rotation of the element during assembly.
Use Scale Curve
The same for the scaling of the element, scaling as extra options to either use uniform scaling or there is also the option to have a per axis scale curve which might be useful for doing stretch and squash effects on elements.
Per Axis Scale
Enable the per axis scale curves.
Scale Curves
Depending on the Per Axis value you will see either one or three scale curves. If one curve then that will apply uniform scaling to the element, if three curves then you can control each axis scaling separately.
Mesh Pivot Mode
For each element this will control where the pivot is, this is important if you have any rotation or scaling on the build animation as it will control how it looks as it rotates etc.
Object - Element will use the main objects position as the pivot.
Center - Element will use its vertices center point as the pivot.
Bottom - Element will use the center bottom point as the pivot.
Top - Element will use the center top point as the pivot.
Rotate Range
You can set how much each element rotates as it builds. You can have either a single value for all the elements or you can have it set a value between two constants for more variation.
Place Mode
Says whether the placement of the element is speed based or time based. It can be useful to say use time if the build distance varies so they will build in order for example.
Time - Use the place time value for the element animation
Speed - Use the Speed value for the element animation
Place Time
If time mode selected then this is how long in seconds it will take for the element to position itself. You can use either a single value or you can have it use a random value between two constants for more variation.
Place Speed
If speed mode selected then this is the speed at which the element will position itself. You can use either a single value or you can have it use a random value between two constants for more variation.
