⬇️Root points projection

Root points are created during brush strokes on objets, but can be projected again after their creation on visible objects, in case the objects moves.

Root points painted | Object moved | Root points re-projected / baked

This can be done using the PCGPainter parameters of any PCGPainterActor:

Use the "BakeProjectedRootPoints" to re-project and re-baked root points on visible objects, scattered points will be recreated using the new root point positions.

Projection mode:

Two projection modes are available:

• "Hit normal", the root points will be projected in a direction defined by the hit normal of the existing root points when there where drawn the first time.

• "World Z", the root points will be projected using a top - down direction only.

Hit normal projection

World Z projection

RaycastLenghtMultiplier:

This parameter is used to create the projection lenght, it's defined using the brush strokes radius * RaycastLengthMultiplier.

Show trace debug:

If on, green lines will be displayed with the lenght and orientation of the projection on each root points.

Draw time:

The amount of time in second the debug projection lines will be displayed.

Bake root points on end stroke:

If ON, force to rebake the root points on each brush strokes "mouse release".
