3d heart model

Heart Material Description Type: Living muscular tissue (Cardiac Muscle Tissue) 🎨 Color Base color: Deep red with a purplish tint. Subtle variations: Brighter red areas near small blood vessels. Slightly lighter, pinkish tones in surface tissues. Contains small shiny spots caused by moisture and blood. 🌈 Reflection and Glossiness (Specularity / Roughness) Glossiness: Medium to high in certain spots (due to wetness). Roughness: Around 0.25 – 0.4. The surface appears slightly wet and glossy, but not mirror-like. Reflections are soft and diffused due to the fibrous texture. 🧫 Texture / Bump The texture is fibrous and muscular, with a visible direction to the fibers. Fibers run in slightly diagonal or interlaced lines. Very subtle depth variation — tiny ridges resembling muscle fibers. Use a normal map with fine longitudinal lines to represent this structure. 💧 Moisture and Transparency The surface is wet, covered with a thin, shiny biological fluid layer. Transparency: Very low, but Subsurfac
