Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing a program and method for updating element properties based on distances between elements in a virtual conference. The program and method provide, in association with designing a room, an interface for specifying how a first element in the room affects at least one property value of a second element, based on distance between the two elements; receive user selection of parameter values specifying how the first element affects the at least one property value of the second element based on the distance; provide a virtual conference between plural participants within the room including the first and second elements; update the at least one property value of the second element based on a change in distance between the first and second elements, and on the parameter values; and provide for updated display of the second element.
