Note that when setting your spotlight, you can either just single click in order to place it, or you can hold the shift key to set things like cone angle, penumbra falloff, and more. While a sphere light is a light that shines in all different directions, a spotlight is basically a light with a direction associated with it. Now let’s add a couple spot lights to our image.
Though the visible wattage of the light doesn’t really correspond with the power usage of bulbs, this still allows me to set my lighting in a way that it makes sense to me. I’m also going to adjust the radiant power units to Watts and set it to something like 80. In this case, I’m going to take this point light and adjust its size so that it fits within this lamp in my model. Instead, go in to your camera settings and adjust your camera exposure to bring your lighting level up. One thing to note – if your image is not bright enough, that doesn’t necessarily mean you need to go in and run the intensity of your lights up to a super high level. You can adjust the power of the light both by scaling it up and down, and by adjusting the intensity within the lighting section of your asset editor. Basically, a sphere light is a light that emits light in all different directions equally. To start off, let’s add a sphere light to your model. Now, let’s take a look at some different lighting options. You’ll note that you still get some exterior lighting from your background image, which you can adjust within your settings section.
To start off, turn the sunlight off within your lighting section of your Vray asset editor. You’ve basically got a few different options for lighting your interior models with artificial lights – this is assuming that you don’t want to light your model with the environment lighting in Vray (sunlight and background lights). In this Vray and SketchUp tutorial, learn about the different kinds of artificial lights you can use to light your interior renders! Learn to use sphere lights, spotlights, emissive materials, and more to create realistic lighting in your interior models!
