About dynamic indirect lighting

Hi Guys,

I used a scene in the dynamic lighting, but there is no dynamic indirect light, I would like to know the specific use of dynamic indirect light?Any help will be appreciated.

Dynamic Indirect Lighting is either a skydome, potentially with distance field ambient occlusion, or full dynamic GI. Not sure which one you are thinking of?

There are hundreds (and hundreds) of posts on dynamic GI. All techniques are currently either quite limited or very expensive - but hopefully something that will improve with better GPUs and future development of the engine.

I think what I need is dynamic GI,Thank you for your help!

Why do you need GI?
