帮我翻译成英文你得在项目前期做好光照设置在这个世界他们是地底发光使用了技能之后rasengan跟bijuu dama 就变成了光源角色身上的光影一定要根据这个光源来设计

You need to set up the lighting in the early stages of the project. In this world, they emit light from underground. After using the skills, Rasengan and Bijuu Dama become light sources. The lighting and shadows on the characters must be designed based on this light source.
