The formation of surfaces with well-controlled non-flat topologies is of relevance for many applications.Here we present a more general method to form surface protrusions in a non-patterned chiral-nematic film by localized exposure. We demonstrate that by adjustment of composition and curing conditions one can either make an elastic film that forms dynamic protrusions that disappear as soon as the exposure stops or deformable films that have permanent surface relief that do not disappear even after a heating treatment.
