Multi Material Render is an add-on that automates the process of rendering multiple material variations into a single composite image. It allows users to quickly showcase different material options on a model without manually rendering and combining separate images. The generated collages include an optional enumeration feature to clearly number each variation, simplifying feedback and communication with clients or team members.

Additionally, the tool streamlines material assignment. While in Edit Mode, users can select geometry, and the add-on will automatically handle assigning those polygons to the correct material slots. The system currently supports rendering collages containing up to 64 different materials.
