Various implementations disclosed herein include devices, systems, and methods that adjust a combined user representation via light normalization techniques. For example, a process may include obtaining a first user representation of at least a first portion of a user generated via a first technique based on the user in a first lighting condition in a first physical environment. The process may further include obtaining a second user representation of at least a second portion of the user, the second user representation being generated by generating and delighting an initial user representation based on a lighting representation of a second physical environment having a second lighting condition, and producing the second user representation by relighting the delighted initial user representation based on the first lighting condition. The process may further include generating combined user representation based on the first user representation and the second user representation.
