Syntax

class PreviewFactory extends RefCounted

Members

Name	Kind	Summary
`WARNING_INVALID_ENTRY`	Field
`GHOST_MODULATE_ALPHA`	Field	Ghost transparency for 2D object previews. The preview renders ABOVE the validity overlays (preview_instance_z_index over indicator_z_index), so an opaque ghost hides the per-cell valid/fail colors beneath the art. Matches the 2D terrain ghost alpha (TerrainPreview.preview_self_modulate).
