Which Blender version does the Eclipse add-on need?

Blender 4.2 or newer. That is the minimum version set in the add-on’s own metadata.

Where is the Eclipse panel in Blender?

In the 3D Viewport sidebar. Press N to open the sidebar and click the Eclipse tab. You will find two panels there: Eclipse and Eclipse Armature.

How do I connect Blender to Eclipse Animator?

Click Start Server in the Eclipse panel in Blender. Then open a file in Eclipse inside Roblox Studio and use Blender Import. The panel shows the direction (Blender → Eclipse or Eclipse → Blender) and whether the link is Live or Paused.

How do I export a Blender rig to Roblox with Eclipse?

Select your armature, open the Eclipse Armature panel, set Studs per Unit (1.0 by default) and click Export Armature (.json). Then import that file in Eclipse. The official tutorial shows this at 11:07.

I get “Another Eclipse armature exporter is registered”. What do I do?

You still have the older standalone exporter enabled. Disable it in Blender’s add-on preferences, then enable Eclipse again.

Is the Eclipse Blender add-on free?

Yes. It is published on GitHub by riftkuro with downloadable release zips.

Using Eclipse Animator with Blender

Quick answer

Eclipse Animator has a free Blender add-on (Eclipse Blender, Blender 4.2+) on riftkuro’s GitHub. Install the zip in Blender, open the Eclipse tab in the N sidebar, use Export Armature (.json) to bring a rig into Roblox, and Start Server to link animations both ways.

Eclipse ships a free Blender add-on that moves rigs and animations between Blender and Roblox Studio. This guide uses the add-on’s actual panel and button names, read from its source code.

What is in the Eclipse tab

Button	What it does
Start Server / Stop Server	Opens the link that Eclipse connects to when you use Blender Import in an open Eclipse file.
Send Animation to Eclipse	Samples your paired output rigs and cameras at the Eclipse file’s frame rate and sends them over. Appears once a session is connected.
Import Rig (.obj)	Imports geometry, bone hierarchy, attachments and materials that Eclipse exported.
Add Camera Rig	Adds the supplied camera rig, including its scale-driven field of view.
Export Armature (.json)	In the Eclipse Armature panel. Exports the selected armature with its control dependencies, bind transforms and bone visuals. Set Studs per Unit first (default 1.0).

Bring a Blender rig into Roblox

Select the armature in Blender.
In Eclipse Armature, set Studs per Unit to match your scene scale.
Click Export Armature (.json) and save the file.
In Eclipse in Roblox Studio, import the armature. See 11:07 in the official tutorial.

Send animations between Blender and Eclipse

Open your animation file in Eclipse in Roblox Studio.
In Blender, click Start Server. The panel reads “Open a file in Eclipse, then Blender Import.”
In Eclipse, use Blender Import. Blender then shows the paired objects and the direction, either Blender → Eclipse or Eclipse → Blender, plus Live or Paused.
To push your Blender animation across, click Send Animation to Eclipse.

Custom output rigs need to be paired in Eclipse first. The add-on reminds you: “Pair existing custom output rigs in Eclipse.”

If Blender shows “Another Eclipse armature exporter is registered,” disable the older standalone exporter add-on and enable Eclipse again.
