A simple Heart Shaped Lock lovingly textured in Substance Painter. The lock and key come with 5 possible texture sets, Rough Steel, Dirty Steel, Rusted, Clean Scratched Bronze, and Lightly Corroded Bronze. The chain Has 3 texture sets to choose from; Rough Steel, Corroded Steel, Rusted. Each of the 12 Chain links is separately UV mapped (same texture file + UV Islands) and textured to eliminate repeating textures, and need only be arrayed to the desired length.
Actual Lock Poly count is ~4k without the key and chain, and the model is included in .blend, .fbx, and .obj formats.
The models do not come as the final composition, but as separate objects for easy usage in your own scenes.
