Irradiance maps from several adjacent frames are loaded together and blended so as to reduce flickering. V-Ray automatically disables rendering of the final image in this mode - only irradiance map prepasses are calculated.Īnimation (Rendering) – In this mode V-Ray renders a final animation using irradiance maps created with the Animation (prepass) mode. Note that in this mode you have to render one map for each frame (i.e. One irradiance map is created for each frame and written into a separate file. This mode is useful when compiling an irradiance map to render multiple views of a static scene or a fly-through animation.Īnimation (Prepass) – In this mode V-Ray calculates irradiance maps to be used later on for final rendering with the Animation (rendering) mode. Incremental add to current map – In this mode V-Ray uses the irradiance map that is already in memory and only refines it in places that don't have enough detail. Note that this mode is not supported for distributed rendering. This mode is useful when compiling an irradiance map to render multiple views of a static scene. This mode can be used for fly-through animations and works well in network rendering mode.Īdd to current map – In this mode V-Ray computes a completely new irradiance map and adds it to the map that is already in memory. V-Ray computes a new full-image irradiance map for the first rendered frame for all other frames V-Ray reuses and refines the irradiance map that has been computed so far.įrom file – In this mode V-Ray loads the irradiance map from the supplied file at the start of the rendering sequence and uses this map for all the frames in the animation. Multiframe incremental – This mode is useful when rendering a sequence of frames (not necessarily consecutive), where only the camera moves around (so-called fly-through animations). In doing so one must make sure that the irradiance map is of sufficiently high quality to avoid flickering. This is the mode to use when rendering animations of moving objects. A single irradiance map is computed for the whole image, and a new irradiance map is computed for each frame. These can be reduced by using higher settings for the irradiance map (the High preset, more hemispheric subdivs and/or smaller Noise threshold for the DMC sampler). Note that since each bucket is computed independently of the others, there may be differences at the bucket edges. Bucket mode – In this mode, a separate irradiance map is used for each rendered region ('bucket').
