SMPL-H vs SMPL Shape Parameters

[kidkych]

Hello, I've read that the SMPL-H and SMPL shape parameters are equivalent; I've also seen that for both cases the betas come in sizes of 10 or 16. Since the betas represent a PCA space, would it be correct to grab the first 10 elements from AMASS datasets that provide 16 beta parameters when we are using a SMPL model with just 10?

I know it's been quite some time since this, but do you know if it worked? I have the same issue but with the 'poses' parameter. I'm trying to use the data to synthesize virtual accelerations using the SMPL model instead of SMPLH, so the length of the vector containing the poses should be 72 (3 angles * 24 joints) instead of 165 (3 * 55). I've tried shortening the vector and keeping the first 72 values but it doesn't seem to work.
