Is there a mesh vertex limit for mobile?

[Gealbhan (Shone)]

I have imported a mesh of a human body for a project I’m working on. The original mesh we bought from a 3rd party, I’m not sure of the vertex count, but it is very detailed. When imported into the Unreal Engine, the model loads in fine and the editor and playback work fine. When Launching on my Nexus 7 (2013) it looks like the attached image. Using logcat, I found the following message:

Mesh has more than 65535 vertices, Incompatible with mobile. forcing 16-bit (will probably cause rendering issues)

Does Unreal limit the amount of vertices per mesh on mobile? I have loaded the same model into Unity 3D and it worked fine on my tablet, so I’m wondering if there is a way around this?

Yes UE4 only uses 16-bit Index Buffers on mobile at this time, I did see talk of them planning to increase to 32-bit for mobiles at some point. So until then the limit is as you have seen 65535 vertices.
