The Agony of dForce

3D

(For anyone who’s not immediately up on obscure references: check out the beginning of the Wide World of Sports from the ’70s. The title is a variation of “the agony of defeat.”)

Okay. So, a couple days ago, Daz Studio released the new version (4.10 if you’re interested). It includes a new feature, the dForce engine, which allows actual dynamic cloth right there inside Studio, without having to buy anything extra. And everyone’s been playing with it and posting their results, which has had me extra-bouncy and excited, waiting for the weekend. Aka today.

A little note here: I have terrible bad luck with dynamic fabric. Like, I don’t know if I’m terminally stupid or what, but I can almost never get the stuff to work right. So I started out with pretty low expectations.

And oh boy, did I ever meet them!

First, I set up a scene. Then I ran out of time, saved it for later, and went to work. That sucked.

Fast forward a bit to today. I forgot about my original scene and set up a new one. I made sure there wasn’t a bit of poke-through anywhere to be found. I made pretty hair, nice lights, good skin, the whole nine yards. See? This is what it all looked like before I pooched it.

Okay, doing good so far. I used that particular hair because a friend of mine from deviantArt said dForce works better on older hair models without loads of strands. Fine. No problem. I’ve always liked the Radiant Jaguar hair, it’s pretty.

So… add the dForce modifier. (Actually, spend a freakin’ long time looking for the damn thing, because as you can clearly see from the screenshot, my Studio looks different from anyone else’s on the entire planet. Found it, though. And if you’re looking for it too, right click the Simulation Settings tab.) Blithely assume it will work. Click “Simulate”.

And… freak out!

I forgot simulations start from the default pose. *blush* Oops. Thought I’d already screwed something up.

Which, of course, I did.

Yeah, that looks like shit. Right. On to the next thing. I’ll fix the hair later, time for the dress.

CRASH!

Yeah. Blew up my computer. Daz Studio and Photoshop both went kablooey.

Okay, fine, I don’t expect this dForce thing to work with every piece of clothing out there. So I pull up the other file, the one I started immediately after upgrading my Studio.

Crap. Forgot to give her a lantern. I get the scene all fixed up and ready to go, although I didn’t bother with any fancy materials or lighting. I add modifiers, make sure the dress will ignore the lantern, hit Simulate, and…

Not a crash, but still swear-worthy. Studio suddenly can’t locate any OpenCL device on my computer. I have one. I have a very nice one, in fact. But apparently it’s gone invisible.

Crap, crap, crap.

So I do the usual stuff. Restart, blah blah blah. I even updated my graphics driver. Why the hell not, never hurts, especially when you’re doing crazy 3D stuff.

Crash, crash, crashity crash crash!

Fine. You want to be a piece of crashing shit? I’ll fix you!

New scene. G8F, the clothes they sent out specifically for the dForce update. Boring. Mundane.

Hey, look at that, it’s doing it! Wow! It’s working! Even past the point where it crashed before.

5

Success! Too bad it’s a freakin’ boring, mundane, utterly uninteresting image. Bleah.

But I got it to work. So… back to the cool stuff.

6

Much more interesting outfit. And look at that, no crash yet!

7

I can see her butt.

CRASH!

Aw, hell. Here we go again. Finnegan, begin agin.

By the way, this is what the scene looks like before the sim runs.

And…

This is what it looks like after the sim runs. *sigh*

I guess I really need to spend some time with this thing, figure out what exactly is making it blow up. But for now, no more. I’m in the middle of an Elder Scrolls experiment, and must go play Skyrim.

If you’re curious, the experiment is this: Can I determine which game is better, Oblivion or Skyrim? To test whether this question is answerable, I started new characters in both games. So far I’ve completed the main quest in each, built a nice home in each, and am about to embark on the mage guild/college quests. And guess what? I ain’t got an answer. I love ’em both!

  1. You know what I’d do? Run the sim first with only the absolute necessary minimum in the scene (i.e. only the objects you will include into simulation). Freeze the sim when you like the results (or, in an even more paranoid fashion, save out a copy of the scene, export the drapes as OBJ files, delete the sims, re-import the static OBJ files). And only then add everything else, materials etc.

    In a “cluttered” scene, it’s too easy to miss an object you don’t want to influence the sim. And if it’s boned, especially if it’s Poser rigging, you will need to select _all_ bones and only then hit “invis in sim”. Yes you probably have that mCasual’s “select all children” script too, and yet it’s too easy to forget about this.

    BTW hair isn’t officially supported yet, so messing with older models even is “advanced stage” now.

    There are still some puzzling quirks to dForce, but it’s really the best addition to DS in a long while.

    1. Thanks! I’ll keep that in mind. One of these days, I really will get the hang of this dynamic stuff, I swear, because the stiff shapes of clothing that should be soft and flowing really drives me bonkers.

      1. You’re most welcome =)
        Oh, another thing to watch out for is “clipping” poses – the same as with Poser and other timeline drapes, if an object (a bodypart, whatever) goes through the sim as if it wasn’t there… at best it “simplodes”.
