Render several distinct materials on it

Invent an object and render at least 3 distinct materials on it under one light, without reference.

What it is

This capstone combines form, value, light, and color to show materials such as metal, fabric, skin, plastic, glass, wood, or stone on one invented object.

You decide how shiny, rough, soft, translucent, or dense each part is. You use edges, highlights, reflections, and texture to show those properties.

The materials share the same light, perspective, and palette. The result reads as one object with a consistent setup.

You can check it when

• ✓Paint one invented object with 3 or more distinct materials, such as metal, leather, and glass. Check that each material can be identified from its visible surface cues.
• ✓Flip, zoom, or shrink the image. Check that the object still reads as one solid form under one light, with no area appearing as a disconnected texture patch.
