Missing Bones (that have weights) when Importing - Import 3D's Show Rig Bones

[Reditect]

Edit: This is a visual bug with the Show Rig Bones part of Import 3D. After importing the mesh into Roblox, the bones are there in the Explorer and work fine.

---

Steps:

1. Import the FBX file attached via Roblox’s Import 3D.
2. Click the Show Rig Visualization button

Videos:

The bones in Blender (showing that they have weights):

The Keep Zero Influence Bones doesn’t work, but I expect that as the Bones in Blender have weights.

FBX File of Model shown in Videos:

Bharal lowpoly.fbx (288.3 KB)

System Information:

• CPU: AMD Ryzen 7 4700U with Radeon Graphics
• Memory: 8.0 GB
• GPU: AMD Radeon™ Graphics

Beta Features Enabled:

I could write them all out if y’all would like, but showing a video of what I have enabled/don’t is a lot easier.

Expected behavior

All bones should be imported that have weights.

This is just an acknowledgment announcement!

We’ve filed a ticket into our internal database for this issue and will start investigating, we will update you when we have further information.

Thanks for flagging!

Hey @Reditect!
Just looked into this issue, it’s a problem with how we represent/handle our bones in Roblox VS in external tooling.

In Roblox we don’t save the location of end cap of bone, just it’s direction. This means we have to make a best guess of how big the bone is for visualizations.
Previously our best guesses we’re pretty size dependent (we expected models to be around Roblox character sized), and the FBX you attached was quite large, which meant our 1 stud end indicator was for all practical purposes invisible.

I’ve updated the algorithm so hopefully it should work better for imported models of all scales, and that update should be rolling out into studio in the next couple of weeks!
