How to render demos

[niyadhibor]

Hello sir and thanks for the good work on this repo!

I am having trouble with getting TSTAR to work past 1 subtask on any of the assembly tasks (using Sawyer, for the record).
I have seen clvrai/skill-chaining#3, which seems to be related to this problem and suggests the issue may be due to the evaluation function, but this has not been answered in a while so it could be a dead end.
I am thinking there might be a chance bad demos are somewhat at play, which is why I would like to know if unity can render the generated demo files (.pkl)

Thanks for your time
