The History tab controls the render history settings such as location, amount of disk space to use and visibility parameters. Some of the options are available only when Show Advanced Settings is enabled. Enabled– Enables/disables render history, where the V-Ray VFB keeps a history of previously rendered images. LocationUse Project Path – When enabled, creates a new vfb_history folder to use as the History Folder within the current 3ds Max project directory. History Folder – Specifies the location where render history images are saved as V-Ray Image files (.vrimg). Save – Opens a browser to search for a History Folder. Recent – Shows a list of recently used locations for saved render history images. Max Size on Disk (MBs) – Specifies the maximum amount of disk space to use for the render history images. When the history exceeds the specified amount, the oldest images are deleted. Auto Save – When enabled, all rendered images are automatically saved to the history. Auto Save Completed Only – When enabled, all completed rendered images are automatically saved to the history. Auto Load Layers – When enabled, loading an image from history or from the Load image command also loads the layer tree saved with the image. Layers are only saved to .exr and .vrimg files written through V-Ray's own output. The output in Render Setup > Common tab is written by 3ds Max so .exr files saved from there do not have Layers saved. When saving layers to an exr/vrimg file, V-Ray writes a flag indicating whether the color corrections are baked in the RGB channel. For example, if you save an exr from the VFB File menu > Save all image channels to single file option, V-Ray creates an .exr file with corrections baked in. It also saves the layers as metadata and the flag that corrections are baked in. When loading images into the Frame Buffer, V-Ray checks if the image has corrections baked (using the flag), and if such are found, the layers are not loaded because this causes double correction. |
If you want to keep the layers that come with the Max scene, turn the Auto Load Layers option off. If you want to load layers from an external image, enable the Auto Load Layers option and check how you save those images. |
