Create: Flashback

If something isn't captured properly in the recording, please rewind it.

A mod that lets you properly record and replay Create's machines (spinning blocks, trains, etc.) with Flashback.

Create machines are sent to the client in a different way than normal mods, so without this mod they show up empty or vanish during replay. This mod fixes that.

Create: Aeronautics Flashback helps you record Create: Aeronautics (Sable) sub-level machines.

Recommend introducing Fix Flashback to fix the bug.

Installation

Install NeoForge 1.21.1 and Sinytra Connector.
Install Flashback (download the Fabric 1.21.1 version).
Put create_flashback-<version>.jar into your mods folder.
If you use Create: Aeronautics, also install create_aeronautics_flashback.
That's it — just record with Flashback as usual.

Requirements

Minecraft 1.21.1
NeoForge 21.1.x
Flashback 0.30+ (via Sinytra Connector)
Create 6.0+
Sinytra Connector (needed to run Fabric mods like Flashback on NeoForge)

Notes

This is a client-side mod. It works without being installed on the server. Installing it on the server is also fine.
Not compatible with ReplayMod. Having both may break recording. Use Flashback instead.
Not compatible with ServerCoreMod. It may cause rendering to break.
To record Create: Aeronautics (Sable) sub-level machines, you also need Create: Aeronautics Flashback.

Known incompatible mods

The following mods interfere with Flashback's replay features. If you install them, the corresponding feature stops working. Remove or disable them to use that feature:

Mod	Feature broken
BadOptimizations	Night vision is no longer applied during replays
Create: Steam 'n' Rails	Spectator camera stops working
Smooth Movement	Time override stops working

These only affect Flashback's replay features; the rest of the mods work normally.

How it works

Create contraptions (spinning / moving machines) are sent via a special advanced_add_entity payload. This mod includes that data in Flashback's replay snapshot.
Even when you seek (jump to a different point) during playback, the machines are rebuilt from the snapshot, so they display correctly no matter where you start.
Also supports Sable sub-levels (Create: Aeronautics) when used together with Create: Aeronautics Flashback.
