Hunyuan Motion from one sentence, then preview the clip

A 3D animator who needs a human motion clip types one sentence in the browser and previews the motion when the job finishes. Sign in before the job can start. The Generate click checks credits: Fast uses 60 and Standard uses 80. If the balance is short, the credit purchase opens then. A daily claim adds 50 credits; from a zero balance, two claims cover one motion.
