I am trying to import a R1 simple rig from Blender into Roblox. I need to have a bone in the hand which can be used to rig weapons to it, so that weapons are animatable independently of the hand but also follow the hand.
When I import the rig from Blender to Roblox with the bone in the hand, the bone just… disappears. Every other bone stays, this is the only bone that gets dropped.
I’ve repeatedly made sure that it is parented correctly to the right hand bone. I have tried following Roblox’s export instructions for .fbx models exactly, re-exporting multiple times, adding a second extra bone incase it’s somehow false flagging it as a leaf bone and clearing it, but i’ve had no success with anything.
Please note that I’m a complete beginner in Blender. I could’ve easily overlooked something simple related to how you set up a bone or something.
It took me 7 hours of staring at my screen at 1 in the morning to fix this issue.
To any poor soul out there who happens to have this issue. Here is the solution.
Go into Blender. Enter object mode. Shift click your Mesh, then your Armature (in that order specifically - this messed me up). Once you’ve done that, you can access Weight Paint mode with Ctrl+Tab. In Weight Paint mode, clikc your armature, then click ‘Weights’ at the top and click ‘Assign Automatic from Bones’.
This should fix your bone and make it appear when you import it. My best guess as to why this is is for Blender to automatically filter out the ‘leaf’ bones that 3D software sometimes creates automatically on .fbx exports. Either way, this sucked.
