Uploading Sculpt to Procreate keeps crashing

I’m not sure if it’s because it’s a detailed sculpt or what but every time I try to open my sculpt on Procreate via .obj it crashes. Do I need to uv unwrap (or whatever it’s called) every part for it to work? I cleared up more than a fifth of my iPad storage and I’m currently updating my iOS to see if that’s the issue.

Is the file big or small?
If it’s multi-million then Procreate might not like it, usually you want to decimate in Nomad and then uv unwrap before sending to Procreate.

For UV unwrap, yes you need UV if you want to paint on it, but it should not cause Procreate to crash.
