I need to make a Circus Bigtop Tent. I haven't done much modeling where I'm creating things made of fabric , like clothes etc. I've been working from a box and other shapes with sub patch, but I'm having difficulty with the top where it tapers in. Also what's the best way to put in folds of fabric. It seems like it should be simple, but I haven't figured it out yet. Any suggestions or tutorial? Thanks guys.

Like with most things. Consider how it is made in real life and model it that way. Also consider using Cloth FX to allow the sheets of canvas to rest in place and then save trans object. But do one sheet or piece at a time. Also consider how those parts were made. How they are cut to make the shapes so they will fit the frame underneath.

I'd suggest this is a GREAT TIME :) to experiment with spline patching.

(If only spline patching were interactive/procedural. ::sigh:: )

It really is a neglected method, --maybe it's just me. Also, Sensei/TrueArts has some pretty awesome spline-centric tools. And I haven't really considered it, but perhaps some of the 3rdPowers plugins would be helpful too. --Anyway, my thought is the catenary curves characteristic of a tent are easily done with splines.

This only took a couple minutes, although I could have chosen patching parameters more wisely:

Here's the object:

Read up on Spline Patching and have at it. You'll have to dink around with it (FLIP Curves mostly), but it should show the path.

EDIT: Hmmmm, with just 3 splines and this extreme pointedness, it's possible for the ,ummm, "BANDSAW loops" to CROSS! :eek: I think with 4 splines that won't happen, so you might want to truncate the top of the cone with a very short spline.

OR, if you have a clever way of making concentric squares*, you can just MOVE w/FALLOFF and get the same effect once it's subpatched. :D

** 4 sided 'flat' Cone

There's also the plugin 'Dome Maker' that can make a tent roof.

!!! What a surprising thing to have made! How did you happen to find that?

Oh, I've been alive for too long and know too much for my own good...

I would approach this in two ways.

1. I would do some test cloth sims, using cloth fx or bullet dynamics
2. I would make each section separately and look at videos on how to achieve the crunched fabric look. Here's one video that may help: https://www.youtube.com/watch?v=6ACslURz1Go

Either way, I would do some research on how really tents are constructed.. are they all one piece, or do they have a separate roof (which overhangs the side parts).
