Thread: Best way to model stairs?

  1. #1

    Best way to model stairs?

    Looking for advice on modeling stairs, particularly the old stone steps you'd find in castles and the like. In the past I've tried various things involving cloning, boolean subtraction, and various other things, and haven't really found a "good" answer. There always seems to be "extra" geometry that causes problems or some other glitch that makes it hard to further modify the object. Wondering if anybody has any tips for modeling good-looking staircases in a reasonable amount of time (unfortunately, I'm up against a clock here.)

    Do you have LWCAD? It's perfect for stuff like this.

    You're right, it looks like it would be great for this but for $329 I could buy real stairs LWCAD will have to wait until I get my next raise, I'm afraid. This afternoon I'm experimenting with extruding n-gons and seeing if that'll give me the results I want. Hopefully my modeling skills have improved since the last time I tried something like this.

    option #1-19; LWCAD
    option #20; Model step - clone radial array with offset + adjust bottom polygon depending on type of stairs
    option #21; multishift the stair

    all options #1-19 is faster than either of #20/21

    oops, ernpchan beat me to it

    I've never used it, but there is this plugin.

    Well, when I built my house, they requested $5000 extra just to get the stairs painted.. but I know what you mean. To solve ONE problem it's steep, but you will love it

    I've had a little bit of success just using front-face boxes, arrayed, UV'd, knifed, and jittered. Not sure how close you want to get or how photorealistic it needs to be, so this technique may be worthless to you.

    The basic stairs is:

    1) Make a box to represent the bottom step. No subdivisions yet. For example, a box 1m wide, .2m high and .3m deep.
    2) Delete the back, bottom and sides of the box, leaving the stair riser and tread
    3) Rotate it around the X axis until the corners are aligned on the Z axis. Note the amount rotated in the Numeric panel
    4) Use the Array tool to create however many steps you want in the Z, using automatic placement
    5) Create a "Stone Stairs" UV Texture in the Y axis. Note that this contains both the riser and tread
    a) also create the Stone Stairs surface
    b) load up a Stone image, adjust the UV size
    6) Put wear and randomness on the stairs by using Knife to make seven cuts:
    a) Top View: two down each side close to the edges
    b) Top View: one approximately down the middle
    c) Top View: two down the sides where the wear begins
    d) Side View: one down the outer corner of each step to square off the tip
    e) Side View: one down the inner cornerof each step
    7) Convert to subpatches
    8) Rotate the array back to vertical (negative of the amount in step (3))
    9) Select the inner points of the outer edge of all steps, use Jitter by about 3cm in each dimension
    10) Select the three inner points of the outer edge of all steps, use Magnet to drop them down for serious wear
    a) use the right-drag to form a very narrow, very tall affect area in the Back View
    b) slightly drag down from the Side View, then press Undo
    c) use the Numeric panel to Magnet-drag the inner points down about 3cm or as desired
    11) If you want to use Bend to make the stair curve, it works fine
    a) if the stairs are going to be different widths, that should be done before creating the UV map in step (5)
    12) Save the object, send to Layout
    13) Copy the Color UV Map into the Bump layer, with 200% Bump
    14) Set up a Spotlight obliquely to bring up the bump layer

    I've attached a sample scene, object and the texture (a free texture from the web).

    thank you

    just needs some more tinkering / improvement, but could provide useful in some cases i think...

    egearbox, you can still do this even without his plug-in, you'll just have to weight them manually.
