Autodesk Forge Viewer modifies default render settin

the default rendering style of viewer and the rendering style in the settings are not very suitable for my needs. Is there any way to set the default rendering effect of viewer? For example, the following two pictures, the first is the default rendering effect of Autodesk Forge Viewer, and the second is the rendering effect of other software in the browser. I want to set the default effect of Autodesk Forge Viewer to be the same as the second one. How should I set it?
