Debugging

Rendering Debugger

Flora creates a tab in Unity's Rendering Debugger window. A shortcut for the tab is available in the top menu bar: Flora -> Rendering Debugger.

The debugger can also be viewed in game in a development build with the shortcut: Ctrl + Shift + Backspace

Properties

Debug Shading Mode

• LOD - Colors each instance by which LOD is currently active.

• Instance ID - Colors each instance by its unique ID.

LOD Mode

• Force LOD - Forces all LODs to a specific index.

• Only LOD - Displays only a specific LOD index, all others are considered culled.

Spatial Hash

When enabled, displays gizmos for each level, block, cell and chunk within Flora's instance spatial hash. Useful for determining how instances are divided in the scene.

GPU Occlusion

• Force Never Occlude - Disables occlusion.

• Occlusion Overlay - Shows a heatmap overlay visualization, where red areas indicate the hot spots of instances being culled by occlusion.

• Depth Overlay - Displays the downsampled depth map used during occlusion.
