1. An image rendering method performed by an electronic device and the method comprising:
acquiring, by the electronic device, first texture data of a virtual object and conversion parameters corresponding to second texture data of the virtual object;
performing, by the electronic device, based on the conversion parameters and the first texture data, fitting rendering to obtain a fitted rendering image comprising the virtual object;
updating, by the electronic device, the conversion parameters and the first texture data based on a rendering loss between the fitted rendering image and a reference rendering image comprising the virtual object, wherein the reference rendering image is a rendering image that is obtained by performing rendering based on the second texture data; and
performing, by the electronic device, based on the updated conversion parameters and the updated first texture data, real-time rendering to obtain a target rendering image comprising the virtual object.
