Built from start to finish. Textures are 2048. Based on a manhole cover image I found online, on Wikipedia. low poly model built in Blender, textured in Substance, with a little help from Photoshop to crop the image of the cover, and used Materialize to create maps based on that image. Once finished, it was exported to Unreal Engine, and Sketchfab. There could be a few refinements that I may come back to once I get a better handle of substance, but this one of those "trial by fire" projects that I need to let sit for a while. I'll post some screen captures of the prop in Unreal Engine soon. Enjoy!
