For Graven, I have created a few level design tools, not only to ease the process of level design and set dressing but also to create desired looks for the props through the tools.
Cheval de Frise with adjustable width and randomizable stake orientations.
Chains with real-time catenary curve calculation, with adjustable connection points, sag, rotation, twist, unit length and 3 different chain types.
Ladder with adjustable height, width, type, and number of pieces.
Rope bridge with adjustable start and end points, sag, and plank and side-rope frequency. Uses the same catenary formula from the chain.
Row of books with adjustable width, colors, and randomization of the book heights, widths, and colors.
