When rendering, I find light placement excruciating because it’s difficult to predict where the highlights will be. Highlights, even just a couple, tell you where an object lives; they’re as important as shadows IMO.I came up with this def, that uses a camera component from Heteroptera and a light component from Human. You specify where on a surface - or mesh - you want the highlight, and the camera component creates a vector from your “eyeball” to that point. This creates a line of reflection, along which you can place a point light.
This would seem to be something that already exists elsewhere in a better form. Does it? If you play with this, remember that if you change the Perspective view, you have to reset the camera component, and also delete the previous lights.
