The material preview scene has the following requirements in order to be loaded properly:

  • scene must contain at least 1 object with '__thumbnail_target' user attribute
  • scene objects(nodes) that will be listed in the Preview mesh drop-down must have a '__thumbnail_target' user attribute set. Different objects must have incremental values e.g __thumbnail_target=1, __thumbnail_target=2


Features of the loaded material preview scene :

  • scene lights will be listed and their color, intensity and enable/disable properties can be modified
  • scene cameras will be listed in the Preview camera drop-down list
  • objects that have a '__thumbnail_target' user attribute set will be listed in the Preview mesh drop-down

Please note that the loaded scene will replace the current preview scene. If there are no lights and/or an environment texture or color set then the preview thumbnail will render black.
