45° stairs - tutorial

(kilL_888) #1

hey.

i posted this tutorial a while ago on a german forum. i decided i put a english version out.

so, heres my tutorial about how to create stairs in an 90° angle.

first you must create a simple patch mesh (3x3). you need to manipulate the vertexes (“V”) to look like this. goto the primitive inspector to define subdevisions “4” (this will be the numbers of stairs).

then create a brush to cover the patch completeley like you see above. height doesnt matter now. later this will be your stairs and you can define height later.

select the brush and use the clipper tool (CTRL+rightmouse button). a blue dot will apear. do not deselect the brush, just use the clipper tool again on the second edge of the patch. a second blue dot and a yellow line will appear.

now cut the brush in half using the clipper tool’s cutting function (SHIFT+enter). repeat this for all stairs.

the procedure repeats a few times now. in the first 3 steps we cut our stairs into the brush. now we need to cut the pieces out we dont need, otherwise the brush isnt regognizable as stairs.

in the 4. step its important to select each stair sepearately. one stair after another, otherwise the clipper tool would cut into all stairs.

if you have any suggestions or questions feel free to let me know.

Nice tutorial, never knew about the subdivisions thing for patches, that will be very useful :slight_smile: It needs to be H=4, V=1 for the subdivisions. Its nice that you can set H for the number of steps.

For an initial size of 256x256 for the patch I didn’t need to use the tiny grids, it clipped just fine on an 8x8 grid. I wouldn’t recommend the tiny grids tbh though as it makes lining things up tricky as well as increasing the risk of leaks, however in this case the steps would probably be in a detail group. if you need to do that I’d select the 4x4 grid say and do snap to grid, then use the clipper to trim the edges where it needs to join onto other brushwork.

Unless I’m seeing this wrong, this is a 90 degree staircase, not 45.

yes, thanks. i corrected this. the tiny grid isnt neccesary anymore in etqw. in doom3 however, which the original tutorial was created for, the 8x8 grid was a problem though.

apparently :slight_smile: no one ever noticed.

For more and smaller stairs just remember to subdivide the patch by an even amount and not an odd amount to make sure the ‘corners’ align to the grid.

You can do a lot of cool stuff with patches when you subdivide them in the manner and try make new shapes but keeping them aligned to existing patches and/or brushes.

Was a good one for making proper 45 degree bends

yea. you can almost do everything with patches if you use them the right way.

maybe ill redo that 45° bends (cylinders) tutorial and upload some images.
