Joint Orient Intro¶

Structure files will often use joints with orientation info built in.

ORIENT INFO¶

Orient Joints Button¶

Use the Orient Joints button to orient all joints that have the ORIENT INFO attributes. The small Add Orient button can be used to add the attributes to any selected joint.

ORIENT INFO settings¶

Joints have an orientation. Their X, Y and Z axis point a certain way depending on that orientation. These settings let you define which way the joint is pointing. This can be important to achieve certain effects for animators.

Aim Axis¶

The axis of aim. This tells the orientation which direction it should point. Options include X,Y,Z,-X,-Y,-Z. The negative axis flips to the opposite direction.

Up Axis¶

The axis that points up. Options include X,Y,Z,-X,-Y,-Z. The negative axis flips to the opposite direction.

World Up Axis¶

This tells the joint what world it lives in. Most of the time the joint lives in a world where Y points up. However sometimes it can help if the world up axis points in Z or X, especially if a joint is more comfortable with those alignments.

Aim At¶

This tells the joint what its Aim Axis should aim at.

world_X:	Aim in world X direction.
world_Y:	Aim in world Y direction.
world_Z:	Aim in world Z direction.
child:	This tells the joint to aim at its first child.
parent:	This tells the joint to aim at its parent.
local_parent:	This tells the joint to aim at a local parent. Which is like aiming at parent, but with a negative aim axis.

Aim Up At¶

This tells the aim up what space it lives in or what it should aim up at. It tries its best, but AimAt has priority.

parent_position:
world:	Aim up at the world.
parent_rotate:	Aim up in the same space as the parent.
child_position:	The up axis will try its best to point at the child.
	The up axis will try its best to point at the parent.
triangle_plane:	This is the most advanced up. It will create a triangle from Triangle Top, Triangle Mid and Triangle Btm and try to point the up in the same direction that the Triangle Mid points.

Triangle Top, Mid and Btm¶

This lets you set what Aim Up At - triangle_plane uses to construct its triangle. The position in space will be used for each corner of the triangle.

grand_parent:	From the current joint, go up the hierachy twice.
parent:	From the current joint, go up the hierarchy once.
self:	Use the current joint.
child:	From the current joint, go down the hierarchy once.
grand_child:	From the current joint, go down the hierarchy twice.
