A method and apparatus for controlling a special effect, relating to the technical field of image processing. Said method comprises: in response to a touch operation of a user on a model in a current image on a screen, acquiring the touch point texture coordinate information and sliding direction information of a touch point corresponding to the touch operation, the touch point being a point, corresponding to the touch operation, on the model (101); updating, according to the touch point texture coordinate information and sliding direction information, texture information of a texture map corresponding to the model, the flow map being used for representing texture coordinate information of a vertex of the model when the model is expanded into a plane (102); and performing offset control on the vertex of the model according to the texture information of the updated flow map, so as to obtain an updated model (103). Said method can create a relatively real special control effect while ensuring good operating per
