JSON structure & Metahuman

I’m trying to use json data with metahuman rig, but found that json values doesn’t equal usd values. Any advice or mapping guide to repeate usd results? for ex. lipSuck, pucker in json doesn’t equal any animated curves in usd file.

We now include 52 blendshapes matching ARkit now, you can give that a try.

Hi @4omp,

I’m trying to use json data with metahuman rig, but found that json values doesn’t equal usd values

Can you please give more detail on what you mean by usd values or animated curves in usd file?
Which usd are you referring to? usd from audio2face export? or somehow did you export a metahuman rig as .usd file?

Hi, thank you for response!
After some time struggling, found that i have error: "Error: Cannot find curve timesamples " when trying to export from asset male_bs_arkit.usd to UE5.
Json exports fine, but USD not.
Also some strange values in JSON that doesn’t lookls like in A2F preview (look at 2nd screenshot)
