Hi ,
Am doing an interior apartment and i wanna give an option to change the texture during mode so my client can try different options for the floor as an example or the tiles so is there a way i can do that and how can i do it .
Thanks
You can do it in two ways:
-either you just switch the material -> “set material” node
-or you use a lerp node in your material + a parameter to control which texture should be displayed -> use a material parameter collection or dynamic materials: 
Thank you for ur instance replay am really greatfull for that and i will try to test the ways uve explained , i just thought it will required some kind of a blueprint code and button control
