material changed and no lighting within AR


Thank you very much for your help, I will take a look.

BTW, I have download some of the templates from the web, and have put some item onto it, when I do the tracking it does work to display the item for me, but it seems like render as default material and no lighting also (even I put 2 point light into the scene), is that I need to use some of the setting about the “AR project” or there may be some of the material, lighting, post process that I need to shut them off??
