I set my scene with “precomputed realtime GI” and then, I’ve tried to set as “static” the objects that I instantiate in runtime, while playing in my scene. But, the GI doesn’t work.
What is the right way to set the GI with procedural gameobjects?
What you are trying to do it sadly not possible. the so-callced “Realtime Global Illumination” is not truly real-time, it won’t work with procedurally generated objects. This limitation is officially described in the User Manual for GI.
