When I change the underside of the slab to a different material than it was modeled with, I don't see a change. When I tried changing the sides of the slab to a different material, all the surfaces change to that material. <BR /> <BR /> Anyone know how to fix this?<BR /> <BR /> URGENT!! PROJECT DUE TOMORROW!! ANY HELP IS GREATLY APPRECIATED!<BR /> <BR /> Thank you in advance.</T></DIV> Thu, 11 May 2023 11:51:18 GMT https://community.graphisoft.com/t5/Visualization/Changing-materials-within-a-slab/m-p/170073#M6436 Anonymous 2023-05-11T11:51:18Z https://community.graphisoft.com/t5/Visualization/Changing-materials-within-a-slab/m-p/170074#M6437 If you are using AC17 you need to override the Material by clicking the button.
