-Animated growth is achieved via a combination of the [[tooltimeline|Timeline Bar]] and the properties on each of the generators that support growth ([[branch_generator|Branch]],​ [[leaf_mesh_generator|Leaf Mesh]], [[fin_generator|Fin]],​ [[frond_generator|Frond]],​ [[cap_generator|Cap]],​ and [[knot_generator|Knot]]). ​ Caps and knots grow automatically with their parents, the rest of the generators listed have their growth governed by a series of properties in the "​Growth"​ group.+Animated growth is achieved via a combination of the [[timeline|Timeline Bar]] and the properties on each of the generators that support growth ([[branch_generator|Branch]],​ [[leaf_mesh_generator|Leaf Mesh]], [[fin_generator|Fin]],​ [[frond_generator|Frond]],​ [[cap_generator|Cap]],​ and [[knot_generator|Knot]]). ​ Caps and knots grow automatically with their parents, the rest of the generators listed have their growth governed by a series of properties in the "​Growth"​ group.

 The typical workflow for editing growth is to first get the model correct with growth disabled. ​ Then, run the Growth Wizard (described below) to get the basics in place and then fine tune the behavior by editing each generator'​s growth properties and adjusting the overall speed and timing on the Timeline Bar. The typical workflow for editing growth is to first get the model correct with growth disabled. ​ Then, run the Growth Wizard (described below) to get the basics in place and then fine tune the behavior by editing each generator'​s growth properties and adjusting the overall speed and timing on the Timeline Bar.

-Once the wizard has finished use the [[tooltimeline|Timeline Bar]] to control the timing. ​ First make sure your end frame matches the shot.  Then use the "​Speed"​ control and corresponding curve to adjust how fast the model grows. ​ All "​Speed"​ properties on the generators are scalars applied to this central speed value. ​ Adjust the value until the model is at the stage you need it to be in on the last frame. ​ Growth computations naturally have a lot of variation and are subject to curve edits and node edits on individual pieces. ​ The only way to ensure your model is at the stage you need it to be in on a particular frame is to edit the speed and speed curve.+Once the wizard has finished use the [[timeline|Timeline Bar]] to control the timing. ​ First make sure your end frame matches the shot.  Then use the "​Speed"​ control and corresponding curve to adjust how fast the model grows. ​ All "​Speed"​ properties on the generators are scalars applied to this central speed value. ​ Adjust the value until the model is at the stage you need it to be in on the last frame. ​ Growth computations naturally have a lot of variation and are subject to curve edits and node edits on individual pieces. ​ The only way to ensure your model is at the stage you need it to be in on a particular frame is to edit the speed and speed curve.
