GI caching is done using the bake step and bake jobs parameters. For the render job, we use both GI engines in the “from file” mode.

For the GI cache job, we switch your current Irradiance map mode type to “add to current map” and Light cache mode type to “flythrough”. The GI cache is calculated using the selected 'bake step' parameter. The first job is for the GI caching - called the 'bake' scene. This mode will create 2 jobs - GI cache, and a render job.

Camera Animation mode works only with Irradiance map & Light Cache.

Camera Animation - bake and render - This mode should be used for scenes where the camera is the only animated object.

Turning it off will force V-Ray to save separate files for Irradiance map and Light cache. This kind of setup is recommended by Chaos Group. By default, Store direct light is always on. Under the Full Animation mode you have an additional setting you can use - turn on/off Store direct light. Before using Full Animation mode please make sure that your GI setup is set to Irradiance Map & Light cache! Otherwise please use the Render as is mode. Full animation mode works only with Irradiance map & Light Cache. Each GI map is calculated on a separate node, so the process is very fast and stable. With full animation mode, GI is cached for each frame in the selected render range so if your scene is starting at 0 and ending at frame 100, you will receive 101 GI map files. The rendering scene uses pre-cached GI maps from the first job. The first one for the GI caching - called the 'bake' scene. Our plugin creates two jobs in this mode. Generally, if your scene contains more than an animated camera, you should use Full Animation mode.

Full Animation - This mode should be used only for fully animated sceneswhich include objects animations, materials changes, camera or light movement.

It will work “out of the box” in most rendering scenarios. In most cases “render as is” is the mode that you should use. Render as is doesn't have any additional settings either. We do not provide any GI caching options in this mode. Also, it can be used for scene testing purposes or for atypical GI setups like Brute Force with Brute Force, or Brute Force with Light Cache. It's useful for scenes with already pre-cached GI or for shots which do not need GI caching.

Render as is - In this mode your scene renders 'as it is'.V-Ray scene plugin mode selection dropdown
