Models of two concrete tetrapods. The circular one is a classic breakwater element, often used in marine constructions (it's 145 cm in height). The Starblock variant can be used in similar fashion, but it's also used to construct barriers on dry land (160 cm in height). Clean topology, ready for real time rendering.
Included are two sets of PBR textures in 2048×2048 size: Base Color, Height, Normal and packed Occlusion/Roughness/Metallic, one for each of the elements.
Please let me know if you need any custom modifications made.
