Honestly that might be the best idea to make a whole post about this as it might be to do withing more than just these plugins. Did you not make the rig on RigEdit then?
And once again if you want me to look at it I can.
But for now sorry that I couldn’t fully help you with a solution.
But like you said if you make this it’s own post then you might get others to help you who might know wjats up.
its okay! i appreciate the help though! it did make me realize the issue is most likely not with the plugin, but with something else
have a nice day !!
Btw if y don’t mind, may I ask where did y get those rig
I finally found the issue, the scale of a costume viewmodel has to be set to 1, that also includes the model which has been exported to blender from roblox.
Oh, Roblox apparently changed some default settings around, so make sure the PrimaryPart of the rig is set to “Torso” instead of “Head” when exporting it to Blender.
Edit: Alright, I’ve gotten everything working up to when I import my animation back into Roblox Studio. Then it doesn’t play at all. I’m using Blender 4.2.
I have a problem, every time I export rig from studio, there is no file folder opening to save it at a location it just exports and never tells me where to save it. What is the cause of this?
Hey I’ve been struggling to export the R15 from roblox studio to blender, it keeps generating these meta parts and it shows in blender, the blender addon doesnt seem to recognize it since nothing is showing on it, any help would be appreciated.
The meta parts are part of the plugin. They are used to convert the studio object into a blender object.
There is a button on the plugin call clean up meta parts that will remove all thses parts.
I wish there are error handlers. Like mine actually freezes studio and there’s UI glitches. That aside, I hope Cautioned’s plug-in gets an update 
Though when getting rigs, if it crashes, it’s good to rebuild the rig. Sometimes it loops itself, I think?
Another note is the baking. I hope that there’s customizable steps so we can get an optimize amount of keyframes than every frame is keyed. It’s laggy for me when editing in Moon Animator.

Have you clicked build rig in blender yet?
Yes ofcourse, as you can see on the right side, the rig isn’t even existing in the import
What version of blender as you using may I ask?
Hi!
Does anyone knows when I import rig to Blender, body parts are named like this: Rig21, Rig31 eetc, instead of being named like RightUpperArm, RightLowerArms, etc?
I think this is very much so messing my process of exporting/importing animations from Mixamo.
This is what happened when I import animation…
Anyone have any idea how to fix this? Would appreciate it a lot! Thank you in advance! 
Can someone help me with this? (2.80 version)
The animation works in blender but when I export it ‘some’ part doesn’t work (In this instance it’s the magazine)
note: see the reply to this message before continuing
for anyone experiencing issues with importing on >4.0 change the following on line 439:
bpy.ops.import_scene.obj(filepath=self.properties.filepath, use_split_groups=True)
to:
bpy.ops.wm.obj_import(filepath=self.properties.filepath, use_split_groups=True)
Not quite. It depends on your blender version. Use this updated version of the script. This works with Blender 3.0 - 4.2+. (
Blender 4.3 currently not supported, use 4.2 or lower in the meantime)
what scale is the models , the scale has to be set to “1” in the property of all the models (the scale of the individual parts doesn’t matter thought)
Note: Im on Blender 4.2.7 ( I also tried on Blender 3.2.2)
Im able to get R15/R6 rigs working with Roblox’s RigBuilder but I cannot my custom models to properly generate the bone hierarchy when I Rebuild Rig in Blender.
Here is the model with the bone hierarchy (Primary Part is ZM01 which is also anchored, its he only model in the project workspace and centered at 0,0,0). I export using the newer Export Rig Button > Save Obj File
Then in Blender I import File > Import FBX [RBX Animations] Rig Import > Select Obj.
In Rbx Animations Blender Plugin>Rebuild Rig>Connect. The result is an incorrect bone tree.
