PresentationWall

A slideshow display surface. Loads a set of JPEG slides from Supabase storage and renders them in sequence.

❌ Currently not in Creator

Type

pre-defined

3D

The PresentationWall is a 4m x 2,25m opaque Plane. When "controls" is set to true it expands to 4m x 2,5m. Its Origin is at the Bottom-Center (if controls are disabled). Spawnpoint should be {0,1,0} so its 1m above the floor.

Custom Args:

Key	Type	Implemented	Description
file	string	✔️	UUID of the Slide record in the Supabase slides table. The runtime fetches slides_count and loads each {storage_folder}/{i}.jpg
widthcrop	float	⚠️ no-op in Unity	Horizontal crop
heightcrop	float	⚠️ no-op in Unity	Vertical crop
controls	bool	❌	If Controls are enabled at the bottom of the screen, currently always true
grabable	"true" / "false"	⚠️	Whether the item can be grabbed in-experience (common to all types)

Special Notes:

file is not a storage path — it is the id field of a Slide row in Supabase. The behaviour queries supabase.From<Slide>().Where(s => s.id == value) to find the slide folder and count. Signed URLs are generated per slide (1-hour TTL) and loaded as Texture2D.
