Why do all polygons become the same paste after MAYA gives a material?

After maya gives a material, all polygons become the same texture, because before adding a new material, by default, all objects use the lambert 1 material provided by MAYA automatically. The correct way is to add new materials before adding textures to objects.

As for the reference diagram, you switch to the corresponding view first, and then view->; The image plane imports a map from the open interface, and directly selecting an image is the same as selecting the camera where the image is located. Therefore, the size and displacement of the image can be modified in the construction history image plane at the bottom of the camera channel box in the sub-view. After using the reference image, you cannot delete the direct selection. You can select the camera to enter hirearchy, and then click the input and output connections to select the image plane.

Delete it.
