I’m still a newbie to Babylon and I’m trying to change the material of an imported 3D scan by a button click created with Babylon GUI, but it only changes the color of the scan to white. I tried to export it with two materials, so I can use getMaterialByName and change on click, but when I open it with Sandbox, it has only one material. Also, I tried creating new material with new textures, but the scan changes the color to white again.
