Part remover ​

The part remover is used to remove objects smaller than a set threshold from the scene. It can be used both as a standalone tool or as a part of the ReductionProcessor. There are three different threshold types used in conjunction with the Threshold value:

• EPartRemoverThresholdType::PhysicalSize - All objects with a diameter smaller than the actual world space size of the threshold will be removed.
• EPartRemoverThresholdType::OnScreenSize - All objects that are smaller than 1 pixel, when the scene is viewed at the selected OnScreenSize, will be removed.
• EPartRemoverThresholdType::PercentageOfSceneDiameter - All objects with a diameter smaller than the selected percentage of the scene diameter will be removed.

The user can set an overall threshold or one per-material. Objects with a bounding box diagonal smaller than the set threshold will be deleted.

An object will be removed if it is smaller than its set threshold value.

Here is a scene with three materials. Each material has a texture showing the material-specific threshold setting that has been used. An object will be removed if it is smaller than its per-material threshold.

Usage ​

The Part remover can be used through the following entry points:
