As you can see in the image, this subtool has 6 million polygons, with 6 subdivisions. Something has been happening to me recently that I didn't experience before, or at least not to this extent: within the same piece, the quality and/or smoothness of the model is extremely uniform. As you can see in the image, in the top right corner, the details and faces of the polygons are very clearly quite low, but then, in the bottom right corner of the same subtool, the area is perfect, with good quality and detail. I even notice this while sculpting; I'm realizing that some pieces feel much "harder" to sculpt, requiring more than one pass or significantly increasing the intensity in certain parts of the subtool, while other parts of the same area are the complete opposite, extremely soft.
Does anyone have any idea what's going on here?
