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.

The new Raytraced Glass material understands thickness, refraction, and edge darkness.
However, the optimization is impressive. Because Lumion uses rasterization as its base, it doesn't melt your GPU like Unreal Engine does. You get raytracing "accents" rather than full path tracing, which keeps render times down to seconds per frame.
