The embodiment of the invention provides a scene description file generation method and device, and relates to the technical field of video processing. Comprising the following steps: when a to-be-rendered three-dimensional scene comprises a tactile media file, determining the type of each tactile material attribute of the tactile media file; when the type of the first tactile material attribute of the tactile media file is a reference, adding an MPEG tactile texture in a target texture description module of a scene description file of the to-be-rendered three-dimensional scene, and adding an accessor index syntax element in the MPEG tactile texture, setting the value of the accessor index syntax element as an index value of an accessor description module corresponding to the tactile media accessor; wherein the target texture description module is a texture description module corresponding to the first tactile material attribute, and the tactile media accessor is an accessor used for accessing decoding data o
