This is a low poly heart made in Blender, for the Cycles renderer. It employs a PBR shader and comes with Diffuse, Roughness, SSS and Normal maps. Ideal for games, but can be used for production, as well if you subdivide. It's fully rigged, with 27 frames (counting from frame 0) and has 9 already animated bones, that you can pose and animate to your liking or just move the keyframes around to change the frequency of the heartbeats or exaggerate them.
