    Hello.

    I need to set the direction of a spot light based on a 3D position in world space.
    I need the spot light to "look at" that point.
    Is this utility available or do I have to calculate the spot light's HPB manually ?

    Thank you.

    Hello,

    you can calculate a HPB rotation from a direction vector using VectorToHPB() (see Vector Manual). You find an example on this in the lookatcamera.cpp example.

    best wishes,
