In this video I use a Truedepth and ‘Lidar’ scan from the iphone 12 pro (This can work with any mesh or 3d scan) and make a Low Poly copy. I then roughly UV the low poly mesh, bake texture over from the vertex colours and then edit the texture it in texture paint mode.
I show how the texture can be edited in photoshop and cloned in 2d and 3d in Blender. In the final part I do the same with a simple lidar scan of multiple walls, and draw the Lo Poly mesh with planes and bake texture again. I am using Blender 2.9. Normal maps can be baked in the same way and i will make a video discussing this in future.
I usually use Zbrush for this but Blender makes it even easier to explain, its quite hard teaching Zbrush.
