Fabric with folds, vellum, quickly sculpted

(i.e. table cloth) add grid size: 7 7 rows: 2 columns: 2 add remesh node iterations: 8 smoothing: 0.2 target size: 0.06 add uv project node rotate: -90

show/hide UVs

press D -> markers -> uncheck Show UV map

change color of viewport material

press D -> material -> diffuse -> change it (dark grey)

increase memory for undo, set undo steps

edit -> preferences -> misc. -> Undo reserve: 5000 MB for the Undo system add vellum configure cloth node add vellum brush node shape: volume connect the first two inputs click in viewport and press ENTER wait until compiling is complete (ca. 1-2 minutes) (to pin areas: hold shift and draw with middle mouse) use mousewheel to adjust radius and start moving and dragging to create folds (every stroke will affect all previous ones, to turn this off: set post drag frames: 0 check freeze outside) (use several vellum brush nodes to easily group changes) add subdivide node algorithm: openSubdiv Loop (best for cloth) depth: 1 (add filecache and reset solver node, to limit file size!!
