Printed circuit board

Generate tileable PBR maps of a printed circuit board: solder mask, raised traces routed with 45-degree turns, vias, chips with pins, silkscreen marks and indicator LEDs in the emissive map, plus a stylized glowing-trace board. Use for electronics props, screens and science fiction surfaces.

Limits to consider

Traces are random routes on a grid, not a real netlist, and they may cross. Chips, LEDs and silkscreen are simplified shapes without text. The glowing-trace preset is stylized. The relief is shallow and carried mainly by the normal map. Occlusion is a blurred-height estimate, not ray traced.
