# 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`.
