@bun-bun thank you 🙂 I’ll try to figure out, how to handle remaining issues by the deadline 🙂
@smurfmier1985 thanks. The scene has an object called “Volume”. This is just a cube with Principled Volume material. Feel free to examine it. And, of course, you should enable “Volumetric” in EEVEE settings. You can see my settings in blend file too.😉
