Simple Stylized Rotunda House made in 3ds Max 2024, Rizom and Substance Painter. The whole model is a single object unwrapped to a single 2k reso .png UV map. Nothing is overlapping, there’s no bottom part of the model.
There’s a video covering the whole pipeline of modeling, UV unwrapping & texturing this model on my YouTube channel: https://youtu.be/bUkck2nVaso
As usual : best wishes & have a great day!=)
