Techniques are described herein for facilitating the placement of props on maps by an automated prop placement tool that makes use of a trained machine learning mechanism. The machine learning mechanism is trained based on one or more training maps upon which props have been placed. The machine learning mechanism may be trained to suggest placement based on (a) spatial rules relating, (b) prop-specific rules, (c) prop-to-fixed-object distances between props and map structures, and (d) distances between props. Once the machine learning mechanism is trained, the prop placement tool may be provided as input (a) map data that defines a target map and (b) prop data that specifies the set of target props to be placed on the target map. Based on this input and the machine learning mechanism's trained model, the prop placement tool outputs a suggested placement, for each of the target props, on the target map.
