AI Material Effects: How to Create Images with Glass, Metal, Fabric, and More
- Aug 25

There is a category of AI art that stops people entirely — not because of dramatic composition or cinematic lighting, but because of something more immediately visceral: texture. The way light passes through amber resin. The sharp reflectivity of polished black obsidian. The soft depth of bone china. The iridescent shimmer of anodised titanium.
Material-effect AI art uses unusual or striking materials as the defining visual element of an image. This is one of AiJoe's most distinctive specialities, with a rich library of material prompts that have been used and refined by thousands of learners.
Why materials work so well in AI art
AI image generators have been trained on vast quantities of photography — including studio and product photography that captures material qualities in extraordinary detail. They understand how light interacts with glass (refraction, internal glow), metal (specular highlights, reflections), fabric (drape, texture, sheen), and organic materials (translucency, imperfection, grain). The creative opportunity: apply these material qualities to unexpected subjects.
The basic material prompt formula
The foundational structure: '[subject] made entirely of [material], [lighting], [style], [additional detail].' For even stronger results: '[subject], rendered in [material], [how the material interacts with light], product photography, studio lighting, ultra-detailed, photorealistic, clean background.' Examples: 'a rose, made entirely of black obsidian, sharp specular highlights, studio lighting, ultra-detailed, photorealistic, black background.' 'A cathedral, made of bone china, delicate white, porcelain texture, studio lighting, ultra-detailed, clean white background.'
The AiJoe material library
The prompt library has an extensive collection across dozens of materials. Extreme material studies: amber resin (warm, luminous, translucent), bone china (pure white, delicate), black obsidian (deep black, sharp reflections, volcanic), anodised titanium (iridescent colour patterns), candle wax (dripping, soft edges, warm colour). Classic materials: polished bronze, aged copper, frosted glass, clear crystal, stained glass, woven fabric, silk, velvet. Organic materials: moss, wood grain, bark, stone, ice.
Lighting for material effects
Translucent materials (amber, glass, crystal, resin): 'backlit, light passing through, warm internal glow, studio lighting.' Backlighting allows light to pass through, revealing internal structure and translucency. Reflective materials (obsidian, polished metal): 'studio lighting, single point light source, sharp specular highlights, reflections visible, clean dark background.' Fabric and textile: 'soft diffused light, texture visible, drape and fold, natural light.' Organic materials: 'macro photography, raking light, texture detail, natural light.'
The unexpected material: creative combinations
The most striking material-effect images often pair the material with the most unexpected possible subject: classical sculpture in amber resin — the transparency against the solidity. Industrial machinery in bone china — delicacy applied to heaviness. A human heart in polished crystal — the biological made geometric and cold. A tree made of spun glass fibres — natural form in industrial material. The greater the contrast between material and subject, the more striking the result.
Materials as abstraction
At one end of the material-effect spectrum, images become essentially abstract — pure studies of how a material looks in light, without a recognisable subject: 'acrylic pour cells, fluid abstract, coral and teal and gold, glossy surface, abstract, ultra-detailed.' 'Extreme close-up of amber resin, internal bubbles, warm backlighting, abstract, macro photography, ultra-detailed.' These work as decorative and printable art in their own right.
