Interface & Workflow Notes

1. Material Selector Preview Toggle

Purpose

Controls whether material preview thumbnails are rendered in the material dropdown / search list.

This option is mainly used to reduce stutter caused by generating previews when opening the material selector in scenes with many materials.

Entry Point

Edit > Preferences > Editing > Objects > Materials > Material Selector Previews

Material Selector Previews

Behavior

  • When enabled, the material selector displays material previews using the current logic.

  • When disabled, the material selector falls back to ordinary material icons and no longer triggers preview rendering in the dropdown list.

  • The default value is enabled.

Current Scope

  • Currently only affects material preview display in dropdown selectors such as template_ID(...).

  • Does not affect the large preview sphere in the Material Properties panel.

  • Does not affect the final rendering result of the material itself.

2. World Environment Exclude

Purpose

Lets you choose a collection so objects in that collection are not affected by the world environment.

Entry Point

World Properties > Environment Lighting > Exclude Collection

World Environment Exclude

Behavior

  • The selected collection is excluded from world-environment lighting.

  • This is useful when you want to separate environment-light influence between characters, foreground props, and background elements in the same scene.

3. Pose Bone Hide in Outliner

Purpose

Adds a dedicated Outliner visibility flag to each Pose Bone, so large rigs can be kept cleaner in the Outliner without affecting the rig itself.

This is useful for hiding mechanism bones, helper bones, or low-level control layers while keeping the more important rig hierarchy readable.

Entry Points

  • Bone Properties > Viewport Display > Hide in Outliner
  • Outliner > Filter > Hidden PoseBones

Behavior

  • Every Pose Bone has its own Hide in Outliner toggle.

  • This toggle is enabled by default.

  • Hidden PoseBones in the Outliner filter is also enabled by default, so existing rigs keep the same visible result until you disable that filter.

  • Once Outliner > Filter > Hidden PoseBones is disabled, pose bones with Hide in Outliner enabled are hidden from the Outliner tree.

  • If a hidden parent bone still has visible children, the visible children remain extracted in the tree so the whole branch does not disappear at once.

Current Scope

  • Applies only to Pose Bone

  • Does not affect Edit Bone

  • Only changes Outliner hierarchy visibility; it does not change transforms, animation, drivers, or rendering
