Photon Tracing can reduce the time required to rendera clean image by a larger margin, especially in indoor scenarios like car interieurs orarchitectural indoor scenes.» Photon Mode: VRED provides different Photon mapping modes.» Off: Disables Photon Tracing and uses the default full global illumination algorithmin VRED.» Indirect Only: Uses photon tracing to calculate the indirect illumination in acene. This is the most common mode.» Caustics + Indirect: Uses Photon Tracing to calculate indirect illumination andcaustics due to specular materials in a scene.» Interactive and Still Frame Count: The two photon count values specify thenumber of photons being sent into the scene for each image sample. Specifyinga photon count of 100000 photons while having set the image samples set to256 will result in 25.600.000 photons send into the scene for a frame.288
