Adjusting surface rounding
Rounding allows you to create smooth, curved edges on surface layers by adjusting the corner radius. Unlike masks, rounding on surfaces incorporates the layer's perspective, creating curved edges that follow the surface's warping.
Select a surface layer, then click on one or more corners to select them. In the Properties panel, adjust the Rounding value to add curvature to the selected corners. You can adjust individual corners by clicking them, adjust multiple corners at once by shift-clicking, or adjust all corners at once by pressing Enter while the layer is selected.
Rounding on surfaces incorporates the layer's perspective, so curved edges will follow the surface's warping and distortion.
