Cakeify V0

サンプルプロンプトと出力

• プロンプト: PIKA_CAKEIFY A blue soap is placed on a modern table. Suddenly, a knife appears and slices through the soap, revealing a cake inside. The soap turns into a hyper-realistic prop cake, showcasing the creative transformation of everyday objects into something unexpected and delightful.
  • 出力: output_0.mp4
• プロンプト: PIKA_CAKEIFY On a gleaming glass display stand, a sleek black purse quietly commands attention. Suddenly, a knife appears and slices through the shoe, revealing a fluffy vanilla sponge at its core. Immediately, it turns into a hyper-realistic prop cake, delighting the senses with its playful juxtaposition of the everyday and the extraordinary.
