The result? Perfectly crisp shadows that fade naturally at the edges, and glass that actually looks like glass—not frosted plastic. For interior designers, this is a miracle. You no longer have to fake light bouncing off a white wall; the engine does the math for you in seconds. If you render a lot of modern architecture (steel, glass, and concrete), you are going to love this. Old Lumion glass always felt a bit too clean or reflective like a mirror. The new Raytraced Glass material understands thickness, refraction, and edge darkness.

You only do massing studies, urban planning, or very early concept sketches. The standard raster engine in Lumion 12 is still perfectly fine for that, and your current workflow won't break. Final Thoughts Lumion 2023 is a "middle child" revolution. It isn't quite Unreal Engine 5 (which requires a full-time tech artist), but it is no longer a "toy" renderer. It sits perfectly in the gap between fast and cinematic .

If you want to impress a client with a sunset interior shot that looks real enough to touch, Lumion 2023 finally gives you the tools to do it in under an hour.
