When pre-rendering 3D models as isometric 8-directions sprites, should I (1) rotate the camera, (2) rotate the camera + lights or (2) rotate just the object?
I'm so confused about this, and I can't figure out whether the lights were rotated or not, for example when checking Rollercoaster Tycoon 2 graphics.
I even extracted ALL of Rollercoaster Tycoon 2 sprites (~29k pngs) but still can't figure out what exactly was rotated when rendering.
I guess I'll simulate it first in real-life, but the answer is kind of obvious: the sun and the light source are stationary, then either the camera or the object rotates.
But then why every tutorial I saw recommends rotating both the camera and the light? That's what so confusing.
@alfredbaudisch Is rotating the camera + light == rotating the object?
