Hey -

Currently the 75 bone is a hard limit of the engine on mobile devices based on currently specified supported mobile devices.

Thank You

Hey Eric -

I’m in trouble because the model which can display it in ES2 of Unity can’t display in ES2 of UE4.
Can I set more number?

James Golding was kind enough to point me in the direction of this line: https://github.com/EpicGames/UnrealEngine/blob/ab237f46dc0eee40263acbacbe938312eb0dffbb/Engine/Source/Runtime/RHI/Public/RHIDefinitions.h#L814

You can increase it and it will work! (tested on Mobile Preview Renderer, Nexus 5 and Nexus 9)

Deducing from what Eric says however, this may break compatibility on some lower end devices (though I might be wrong about this) Eric do you know why this solution may be undesirable?

Hello all, I am also looking for a sloution to this dilemma. I am using Iclone Character Creator for making my characters, along with Iclone and 3dXchange for animation and export. I am very unfamiliar with bones, and how the skeletons work (Heirarchy and such). Is there a way to either delete unnecessary bones in 3dXchange, or find a workaround for mobile?
P.S. The link provided by James Golding is broken. Any help will be greatly appreciated.
