Noita Material Sim

Search any of Noita's materials, paint them onto the chunk, then Step or Play. Everything is a faithful port of the engine: the exact scan order and RNG, the real movers (liquids flow, powders pile, gases rise, fire drifts and dies on the engine's own 1-in-16 roll), the real reaction tables (acid corrodes, lava meets water), and real combustion — burning fuel throws the flame plume and hot smoke that spread fire. Hover the chunk to see what's under the cursor.
