Slime Girl Concept

Brings slimes to life in Hunyuan T2V generations!

Trained with https://github.com/tdrussell/diffusion-pipe

Training data is small combination of:

• Images used from other versions this model card

• Images extracted as keyframes from several videos

• Short video clips ~40 frames each

Training configs:
