hello, it's my first time ever modeling and i'm trying to work on a Toyota Chaser model, but after removing the all-grey grille as seen in the second picture and replacing it with the black mesh grille in the first image, the model renders with the original all-grey grille. i used the a tool on the right hand side to select polygons inside the part of the grille i wanted to remove, deleted them, and then created the black mesh to go in it's place. any help is appreciated!
