I’m using a Roblox plug-in to import Roblox rigs into Blender for animation, and then export them back into Roblox. R6 works great, but when I try to animate R15, I can only drag the bones, the limbs won’t follow.
hmmmmmm, I never rigged things in blender that were parts based,
I think i’ve seen a couple youtube tutorials that focuses on that though, why don’t you look there?
Yikes! Looks like Orange has melted a bit. Normally, we’d have to use Weight Painting to sort this out, but since we’re working with Roblox’s segmented rigid parts instead of something like a skinned, stretchy smooth rig, we can solve this easily.
Go into Edit Mode onto the melted part, and then in the Properties window, go to the Vertex Tab as shown on the right.
Remove any Vertex Groups that don’t belong to the part, such as “Blue Bone” here, via selecting the group, and then clicking the minus button.
To make sure that ONLY its intended bone controls all of it, select the Vertex Group of its intended bone, set the Weight to 1 in the same window, and press A to select all of the vertices of your melted mesh.
Then, click “Assign” in Vertex Groups.
Use Pose Mode to see if it works now!
(NOTE: A Vertex Group’s name MUST EXACTLY match whatever bone it’s referring to.)
It has nothing to do with weight painting just select both the bone and the part you want to move then control p and then parent to bone. To be clear you have to go to edit mode and then object mode to do this. This video does exactly what I said but visually Rigging a Low Poly Person | Blender 2.8 | Beginners - YouTube
