Import an animation into Roblox Studio

From RoMotion’s R15 export to an animation playing in your game, in five steps.

Open Create

RoMotion exports animations as an R15 KeyframeSequence (.rbxmx), the same thing Roblox’s Animation Editor saves. Here’s how to get one from RoMotion into a running game.

Steps

  1. Export from RoMotion

    In Create, open your animation and choose Export → R15 export (.rbxmx). You get a file with one KeyframeSequence in it.

  2. Add it to Studio

    Open your place in Roblox Studio and drag the .rbxmx file into the viewport, or right-click in the Explorer and choose Insert from File. A KeyframeSequence appears in the Explorer.

  3. Check it on a rig (optional)

    Insert an R15 rig with the Rig Builder. Put the KeyframeSequence inside the rig’s AnimSaves folder (an ObjectValue the Animation Editor creates the first time you save; you can add one yourself). Select the rig, open the Animation Editor and load it from the ⋯ menu. Tweak anything you like and save.

  4. Publish it

    Right-click the KeyframeSequence and choose Save to Roblox, or publish it from the Animation Editor’s ⋯ menu. Copy the asset ID you get. Publish it under the account or group that owns the experience, or it won’t play in game.

  5. Play it from a script

    Load it through the character’s Animator with the asset ID:

-- LocalScript in StarterCharacterScripts
local character = script.Parent
local humanoid = character:WaitForChild("Humanoid")
local animator = humanoid:WaitForChild("Animator")

local animation = Instance.new("Animation")
animation.AnimationId = "rbxassetid://0000000000" -- your asset ID

local track = animator:LoadAnimation(animation)
track:Play()

If it doesn’t play

  • Wrong owner. An animation only plays in experiences owned by the same user or group that published it. Re-publish it under the group if the game belongs to one.
  • Overridden by default animations. The default walk and idle can win over yours. The export uses Action priority; raise it to Action2 or higher on the track (track.Priority) if something still overrides it.
  • R6 character. R15 animations don’t play on R6 characters. Set the experience’s avatar type to R15 in Game Settings.
  • Still nothing. Check the Output window for a failed asset load, and make sure the ID is the animation’s, not the place’s or the model’s.

Using it as an emote or a default animation

To replace a default animation (walk, idle, jump), copy the character’s Animate script while playing, paste it into StarterCharacterScripts and swap the AnimationId in the matching value. For a one-off move like an attack, play it from your combat script the way the example above does.
