While Ray-traced may produce noise, this mode has no such effect - the resulting illumination on the smoke is always smooth. Grid-based – The self-illumination of the smoke will be calculated separately from the light that the Volume Grid casts on the scene using an approximate fast formula. This mode is physically correct and takes into account non-transparent obstacles inside the Phoenix volume, but requires intense computation and can take considerable time to render and clear the noise from the image. Note that the fire lights always illuminate the rest of the scene using ray-tracing. Ray-traced – The simulator's smoke will be illuminated by the fire's light sources using precise but slow ray-tracing. None – Smoke does not obstruct the light propagation and it is brightly lit. To gain back the rendering speed, set Self-Shadowing to Grid-based and decrease the Light Grid Resolution (%) parameter to reduce the number of generated lights. ![]() Self Shadowing | emLightsSelfShadow – Enables self-shadowing of the smoke from the fire's light. If enabled, the smoke will obstruct the path of light from the fire, creating a much more realistic look but decreasing rendering performance. Light Power on Scene | emLightsPowerMult – Controls the light intensity over all scene objects except the Volume Grid itself. This will not change the intensity and color of the fire itself only the illumination over the smoke is affected. Light Power on Self | emLightsPowerOnSelfMult – Controls the light intensity over the Volume Grid's own smoke. Using Generate GI and Receive GI options from the V-Ray Object Properties will be ignored while Create Fire Lights is enabled. You should disable Create Fire Lights if you want to let the GI naturally illuminate the scene. If Create Fire Lights is enabled when rendering using GI, additional light sources will still be created by the fire at render time. To gain back the rendering speed, set Self Shadowing to Grid-based and decrease the Light Grid Resolution (%) parameter to reduce the number of generated lights. If enabled, the smoke will obstruct the path of light from the fire, creating a much more realistic look but decreasing rendering performance. The smoke illumination caused by the Simulator's own fire can be controlled with the Self Shadowing option. The color and power of these lights are adjusted automatically but can be overridden. ![]() Turning on Create Fire Lights simulates GI by placing light sources in the bright parts of the fire, which gives similar results and renders much faster. When using Global Illumination (GI), the fire will illuminate everything automatically but the rendering will take quite long. The Fire Lights rollout controls how the fire casts light on the other scene objects as well as on the Volume Grid's own Smoke. This page provides general information about the Fire Lights sub-section of the Rendering tab of the V-Ray Volumetric Grid. ![]()
