What transform space is used by Actor3D->LightPosition? I'm not sure if it's "world" or "view". I know, it's relative to the actor, but what about rotations? Does this space use same axes/rotation as "World" transform? Or is it somehow aligned to "camera" transform?

It's in world space. It takes actor's world position, adds the values to it, and that's the resulting light position. It's affected by actor's scale, though.

Thanks.

One more question.

How is it affected by scale? Do I need to multiply LightPosition components by scale and then add actor position to get resulting LightPos?

Yes, that's right.
