I am searching how to get true volumetric lighting (not sunshaft effect) into Unity like in Blender EEVEE ( Blender 2.8 EEVEE - Volumetrics Test Japanese Mountains - YouTube ). If the effect is only possible by downloading something in the Asset Store i would prefer something free.
Most of these effects are bloom and for real-time volumetric lights unity has got a git package, use that. If you are on the mobile platform then you will need to fake it using billboard textures.
I think you are looking for this
I want the same effect. Solved it using lens flare and this video helped me a lot to get volumetric effect. - YouTube
