Thank you for sharing your great work.
I'm trying to convert from SMPL to STAR format with AMASS dataset.
However, your converter script doesn't work properly.
https://github.com/ahmedosman/STAR/blob/master/convertors/convert_smpl_to_star.py
I got an error as follows.
ValueError Traceback (most recent call last)

ValueError: cannot reshape array of size 9487530 into shape (93)
According to the result, the shape of star_model["posedirs"] doesn't fit into 93.
In addition, I checked that the shape of the model which was the latest version (1.1) of the STAR model downloaded from your project page.
star_model = np.load(path_female_star, allow_pickle=True)
print(star_model['posedirs'].shape)
(6890, 3, 459)
I think that your converter script doesn't work properly with the latest model (1.1).
Did you change the number of pose blend shapes from 93 to 459?
Could you please tell me how to convert from SMPL to STAR format with AMASS dataset?
