Map Override

The Map Override is a polymesh operator that allows the user to override a particular input from an assigned material. The inputs that can be overridden from a material are Opacity, Bump, Normal, AO, and Light Images.

Example

Imagine there are multiple 3D models that share the same material.

Each model requires its own baked Ambient Occlusion map.

Add a map override to each model via the Add Operator button in the properties panel.

The user can assign each unique AO map to the various models on the platform without having to assign the AO on the material itself. This allows a material to be used across multiple 3D assets.

This polymesh operator allows the user to add the images as either an Asset or Node to each of the 5 categories (Opacity, Bump, Normal, AO, Light). While you can mix and match Assets and Nodes for the various groups, you must select either Asset or Node per section. Thus, the platform will not allow the user to accidentally set Opacity Image Asset and Opacity Image Node at the same time. It will set the selection to either Image Asset or Image Node based on what was set last.

Image Assets are images the user has uploaded to the platform, while Image nodes will select from items created in the current scene. A majority of the time, the user will use the Image Asset instead of Image Node.

It is strongly advised to not use image nodes in current state as they are local variables not global.
