MocapGen is a Roblox animation maker that turns a short English prompt into 4 R15 animation variations. You preview them in 3D in your browser, then download .rbxmx for Roblox Studio, R15 FBX, or Mixamo FBX. Paid generations start at 4 credits.
Some people call it a Roblox animator or a Roblox animation generator.
Information checked October 4, 2026.

Write one or two sentences, like “a tired zombie shuffles forward, arms hanging low.” Open Options to set length, strength, or motion mode.

Every run gives you 4 takes on the same prompt. Play them on an R15 dummy, change the speed, and keep the one that fits.

Download the .rbxmx file and choose Insert from File in Studio. Open it in the Animation Editor and publish it to get your animation ID.

A good Roblox animation maker also saves you time after the animation exists. Here's how.

Motion is hard to put into words. Four takes per prompt means you rewrite less and choose more.
Files come out on the R15 rig, and the .rbxmx drops into Studio with Insert from File. No Blender, no plugins.
Each variation is checked for length, root drift, joint speed, and missing R15 parts, so you see problems before you import.
1 credit per second with a 4-credit minimum. A 6-second move costs 6 credits, and every export format is included.
Use what you make in your games and in monetized videos, on any plan or credit pack.
MocapGen does text to animation for Roblox. An AI motion model creates the body movement from your words, then fits it onto the R15 rig so the joints match a Roblox avatar. You pick the take and can polish keyframes later in the Roblox Animation Editor.
Know these limits before you start:

Every paid generation includes all three formats:
| Format | Where it goes | Best for |
|---|---|---|
| .rbxmx | Roblox Studio, Insert from File | Game animations and Studio scenes |
| R15 FBX | Animation Editor import, Blender | Editing keyframes by hand |
| Mixamo FBX | Unity, Unreal, Blender | Other engines and rendered shots |
