Materials emission

Unity Engine

Hi,
Maybe I’m wrong but GI works only with lights? It’s any way to have good “lights” reflection only with material’s emission? Especially when we don’t see the source? For example, I have a neon without lights, only with emission on material, is any way to see reflection when I will turn away from this neon? Without ray tracing… and in real time.

Thanks

For baked GI, the lightmapper and light probe baker support emissive materials just fine. But it sounds like you are talking about a purely-realtime (no-baking) usecase? HDRP’s SSGI might be applicable Screen Space Global Illumination | High Definition RP | 14.0.11. HDRP also supports realtime area lights.
