Forest cave with stream and bioluminescent undergrowth

3D rendered cave interior demonstrates volumetric light rendering through atmospheric haze. Stone arch framework with elevated canopy layer, tropical vegetation deployment including red flowering understory plants and verdant foliage. Water stream feature with reflective surface properties. Directional sunlight creates pronounced shadow gradient from bright perimeter to dark recessed zones. Composite depth arrangement: foreground vegetation, middle-ground rocky surface, background cavern void. Chromatic temperature shifts toward cool blue-green tones in shadowed areas.
