Here we can change our light object into any lamp type if we choose the wrong type when we added the lamp. That is the green lamp icon.Įxpand the light section if it isn't already open. We can then access the parameters of a light object by selecting it and go to the object data properties tab in the properties panel. However, all lamp types do not take all transformations into account when illuminating the scene. We can move, rotate, and scale the light object using the basic transformation tools accessed through the shortcut keys, G for Grab or move, S for scale and R for rotation. We have four different light object types. You can also use the Add menu at the top of the 3D viewport. To add a light object, press Shift+A in the 3D viewport and go to the light submenu. The most common way of lighting in Blender is through using light objects. In Eevee it is not uncommon to use additional lamp objects to fake the indirect light instead of baking the indirect light with an irradiance volume. But we also use a lot more calculations and rendering of a frame takes much longer than in Eevee. Thanks to Cycles light bouncing, we get indirect light automatically. In Eevee we have direct lighting, and any indirect lighting needs to be baked using an irradiance volume.

These engines handle lighting very differently.

The lighting is what separates Cycles from Eevee the most. Differences between Cycles and Eevee lighting We can also hide or only partially show the scene to create a story or have the viewer make up their own meaning of the artwork.īut before diving deeper into the goals of light and why it is important, we need to know the technical details first. We can separate subject from background and create a guide for mood and emotion. With light, we can put emphasis on the important parts of our scene and guide the viewer's eyes to our focal point. The absence of light is just as important as the light itself. Everything in lighting comes down to contrast. The goal of lighting is to create pleasing and balanced contrast. Studying some photography as a 3D artist is time well spent.īut we can also simplify lighting a lot. This is true for the lighting part of the pipeline in a 3D artist's workflow as well.

It is said that a photographer is a light painter or someone who paints with light. What is the goal of lighting in digital 3D art?
