Obviously, if there are only reflective objects in the scene, then the render could last forever. Until a non-reflective object is finally met and gives the whole chain of rays its color.Įventually, the first reflective object inherits the colors of its environment, Then the ray bounces from its current location and travels up to another object, and so on, Then the ray takes the color of the object. If the first object hit by the ray is not reflective, The principle of ray-traced reflections is very simple:Ī ray is fired from the camera and travels through the scene until it encounters an object. Ray tracing can be used to make a material reflect its surroundings, like a mirror. Reflections are not available in the Game Engine). Mirror reflections are computed in the Blender Render and Cycles Renderers using ray tracing.
