Proper Skeletal Mesh Bone Naming Convention for Non Humanoids in UE Marketplace?

Greetings All. We’re Seeking information and guidance on proper Skeletal Mesh Bone Naming Convention for Non Humanoids for submission and acceptance into UE Marketplace. Skeletal Mesh are various geometric and organic shapes containing singular bones, bone chains, symmetric bones, and bone groups.

Any and all recommendations are greatly appreciated. Thank You in advance.

Hey @TheGameDevStore!

If you are submitting a skeleton that is not a humanoid / using the Epic Skeleton, your bones should just be put together in a legible/understandable way. I suggest doing a root and or the name of what is actually present on the mesh where the bone is.

Good luck with submitting your product!

We truly appreciate your response and recommendation. Unfortunately, the product was submitted on 3 occasions, each declined.

We are using ‘root’ bone, however, creating names of what is actually present on the mesh have been the challenge. Names of specific bones for geometric and arbitrary organic shapes are a little tricky, skeletal meshes for these shapes are not common.

Here’s a example:

The future plan is to use the bone naming convention similar to UE4/5 Mannequin & Vehicle Skeletons and apply to all Skeletal Meshes. To achieve this, we’ll divide the shape into sections on X,Y,Z plane relative to the root directional vectors.

We believe this will aid in creating logical names for singular bones, bone chains, symmetric bones, and bone groups, but anticipate long bone names.

We want to provide a Visual Image or Tool that shows top/front/left view of the division with bones names as an aid.

Hey @TheGameDevStore,

What was the specific reason they gave for the decline? Could it be for a reason other than just the names of the bones? Maybe you could get some more context by responding to your most recent decline.

Unfortunately, No additional details were provided. However, we do acknowledge the Bone names require improvement.

Hey @TheGameDevStore,

In that case I would ask for more information or resubmit and if it is declined again, ask for more specifics about the reasons for the decline. The bone names for non-Epic Skeleton characters should not really affect a decline:

Let me know what they say!

The product was submitted/decline in 2020. Lots of changes since that time. We desire to improve the bone names and add more shapes for a new submission.

We sincerely appreciate your responses and recommendations.
