+ | ====== Lumberyard Wind ====== | ||
+ | SpeedTree leverages Lumberyard' | ||
+ | |||
+ | The procedure for editing wind is as follows: | ||
+ | - Get the vertex colors correct on the model. | ||
+ | - Select the fan and enable wind. | ||
+ | - Tune the fan parameters to get the desired motion. | ||
+ | |||
+ | ===== Vertex Colors ===== | ||
+ | There are two ways to set vertex colors for wind in the Lumberyard versions of the SpeedTree Modeler. | ||
+ | |||
+ | ==== SpeedTree Controls ==== | ||
+ | To let SpeedTree set the vertex colors, do the following: | ||
+ | - Enable " | ||
+ | - Edit the " | ||
+ | - Edit the " | ||
+ | |||
+ | Once you've done that and enabled wind your model should look something like the following screen shot with wind enabled. | ||

+ | |||
+ | ==== Custom Vertex Colors ==== | ||
+ | If you want to control the vertex colors directly, do the following: | ||
+ | - Select the Tree generator and Enable the property " | ||
+ | - Edit the vertex color properties of each generator directly. | ||
+ | |||
+ | You have the option of setting the color directly or setting colors relative to the color they inherit from their parents. | ||
+ | |||
+ | A description of how Lumberyard interprets vertex colors can be found here http:// | ||
+ | |||
+ | Here's a quick reference: | ||
+ | |||
+ | * Red: Fine detail bending for leaves and fronds (1.0 = bend the most, 0.0 = bend the least) | ||
+ | * Green: Timing offset for branch motion (use a different shade of green for a branch and its children to offset branch oscillations) | ||
+ | * Blue: Branch motions amount (1.0 = don't move at all, 0.0 = move the most) | ||
+ | |||
+ | ===== Wind Properties ===== | ||
+ | Select the Fan object to reveal the wind properties. Wind direction is a non-normalized vector in Lumberyard; however, in SpeedTree the direction is set by the fan gizmo and the strength value is one of the properties. | ||
+ | |||
+ | The properties in the Lumberyard group match the bending properties in Lumberyard exactly. | ||
