cave entrance 3d model

Realistic cave entrance interior, viewed from inside the cave looking outward. The cave opening is circular and irregular, formed by natural rock. The cave walls are rough stone with uneven surfaces, cracks, and erosion. The rock is covered with patches of moss, damp stains, and dirt. Large amounts of spider webs attached to the cave walls and ceiling, webs are thin, semi-transparent, tangled, and realistic (not glowing). The cave interior is dark and moist. The cave floor is uneven earth and stone with small rocks and organic debris. No fantasy elements. The opening leads to a bright exterior (white background), the outside environment should not be modeled, only the cave interior geometry. Photorealistic style, cinematic realism.
