The invention discloses an object storage system and method used for cloud rendering. The storage distribution of a model file can be efficiently managed, free network bandwidth is effectively utilized for automatically scheduling the model file, the bandwidth pressure of burst traffic for a cloud rendering network can be lowered, meanwhile, rendered object acquisition time can be shortened, and rendering instantaneity is enhanced. The object storage system comprises a scheduling server, an object storage server, a database server and one or a plurality of 3D rendering servers, wherein the scheduling server, the object storage server, the database server and one or the plurality of 3D rendering servers are connected through a network; the scheduling server is used for sending a push message which contains a popular model file and the external storage address of the corresponding model file in the object storage server; and the scheduling server is used for responding to a received rendering request, and distributing the rendering request to the corresponding 3D rendering server.
