Blender rig exporter/animation importer

I wonder whether anyone is able to offer me some advice on an issue that I am experiencing.

I am currently trying to import Rthro avatars into a game, using the instructions contained within the following resource:

I am able to import the given sample rig into Roblox Studio, with no problems, and I can confirm that everything works fine.

However, the problem that I have experienced is this:

Next I import the given sample into Blender to create a new avatar (I am using the most up-to-date current version of Blender: v2.80) and then I export my work onto my desktop as an FBX export. The issue is that, when I import this FBX file, it contains no attachments. This means that, when I test the new file, my current avatar falls apart and dies.

Is there a workaround (such as a change to my settings, to export from Blender and then import to Roblox Studio. I am sure that I must be making a very basic and foolish error at this step) so that all the attachments can be included? Or is it a case of having to replace the attachments in every limb manually, after the new file is imported to Roblox Studio?

I thank you in anticipation for any input regarding this issue.

You should probably create a new thread or a post in a thread about this importer. This thread is about a different tool.

Thank you Den_S for your input. I shall do that now.

The 2.80 version hasn’t been updated yet to support the release 2.80 version, use 2.79 for now (or an old 2.80 beta).

I’m attempting to follow this tutorial, but when I try to use the export rig on the basic R15 dummy provided by ROBLOX, it throws in the meta parts inside of the obj it creates and I don’t really know what I could do to remedy this, am I doing something incorrect?

Steps that I take that result in the problem:

  1. Created a blank studio place with just a baseplate
  2. Spawned an R15 block rig from the ROBLOX rig builder plugin
  3. Removed the baseplate, and centered the HumanoidRootPart at 0,0,0
  4. Click on the rig with the blender animations plugin
  5. Press export rig in the plugin
  6. Look at obj and see the meta parts are within it

Heres the place I used:
Baseplate.rbxl (22.9 KB)

The meta parts should be in there, when using the Blender addon to import the obj it’ll detect those parts and derive some additional data from them (and not actually import their geometry). Do not use the regular Blender .obj importer, that one will not be able to derive the additional rig data from them.

Hey Den_s,

Do you got any ETA on when you could have the plugin be supported with Blender 2.8 now its officially released?

I am working in the industry as animator and would highly prefer Blender animation over the Roblox Animation Editor or alternative Animation Editors out there.

I used to work within Maya but Blender 2.8 won me over and just like many would I love to see the official support for this fantastic plugin be added to version 2.8.

No ETA, but hopefully in the not-too-distant future.

Note that Roblox has an official FBX animation importer nowadays too, it may be worth to try to migrate your workflow to use that instead. (although I’ve never used it myself yet)

Used your plugin and everything.

Make sure the Roblox plugin does not show any warnings after selecting the rig.

No, there’s no error.

It just says “Done”

Can you send the rig you’re using so I can try it out myself?

Is it possible to scale down animations? Like scale wise?

If you want to scale the position transforms of each keyframe you can use (for example) the graph editor for this in Blender.

The Blender addon has been updated to support the release version of Blender 2.80 now, see the opening post. The UI has been changed slightly to adapt to additional Blender 2.80 UI changes too.

having problems importing fbx animations from mixamo, it’s about mapping them, blender 2.8: i press the “Import FBX” button from the addon tab and i select my file that i downloaded directly from mixamo (on the roblox character), and it gives an error “Cannot map rig, following bones are missing from source rig: list of all bones in roblox character” it’s frustrating because when i normal import the fbx it shows that all names match and movement is perfect, i just can’t map it to the roblox rig, “names aren’t matching” or something? is anyone having issues with this? (i followed some new youtube tutorials too and they seem to be working fine, even copying the exact steps, most of the videos are the same)

I cannot reproduce this, rig mapping still works for me. If you’re certain that the names between the generated rig and the imported rig match exactly, send the blender file + fbx file with the rig you’re trying to map onto it and I’ll check out what may cause it.
