I Don't Understand DForce Outfits Logic...

Justin_Ames

Hi, please I need help :( As much as I try and understand how Dforce products works, I just can't figure it out. I bought the amazing https://www.daz3d.com/dforce-ridge-outfit-for-genesis-8-female outfit and I'm using it with the correct Genesis 8 character it was made for, yet any simulation just make it a million time worst than if I did nothing. After an hour and a half of simulation this is what I get. It makes no sens as on the promos images it works wonderfully with any position. Mine is like it doesn't even realise where is the ground and where is my character literally... What am I doing wrong?..  

Richard Haseltine

Are you starting the simulation from that pose or from a memorised pose, ideally close to the default pose? Even then, I suspect that as the pose changes from start to finish some parts, most likely the left arm, are passing through others which will break the simulation (a Play Range sim, with staging poses set between start and finish to guide the movement, may be the fix if so). Is it a static or play range simulation?

For the skirt, you do need something for it to collide iwth - e.g. a plane with a reasonable number of divisions (Create>New Primitive), and the skirt should not be cutting through the plane at the beginning.

It's a pose from the https://www.daz3d.com/first-light-poses-for-genesis-81-female.

Okay I see. I learned how to do play range simulation with another character for a hat problem one time. I should be good trying this again. 

I'm not sure what you mean by static or play range but I guess it's about if it's only a picture or an animation? If so, my goal is to make a picture only. 

Thank you very much for the help

Even for still renders, you're generally best served doing an animated simulation.

Have you tried hiding the hair and wings before simulation

Olo_Ordinaire

Since I don't do animation, I turn off "Start  from Memorized Pose" in the Simulation pane.  Also, you can either hide the hair and wings before simulation, or select the items in the Scene pane and look at DIsplay under General, and turn off Visible in Simulation.  In this way, the simulation will ignore those objects while calculating collisions.

Some outfits are better than others at simulation, particularly with dramatic poses.  If it still explodes like you see in your example, try looking at the garment in the Surfaces pane and turn off "Self Collide" for all surfaces in the object.  Sometimes that will be enough to get by.

There are other tricks, but these should help for most typical simulation problems.

Start from Memorised Pose isn't related to animation, in fact it is most useful when not animating - it allows the simulation to start in a safe pose, one that won't cause initial intersections, and then progress to the desired final pose (or the beginning of the animation, as the case may be). Even the paly rnage option isn't exclusively for animations - it is also useful when it is hard to get to the final pose without having the outfit or the figure self-intersect, or to allow other items (furniture or special helper objects) to push the cloth around.

Okay, thanks Richard.  I just learned to turn it off when I had product environments that had props that started marching around the room when I tried to do simulation of a garment.  "Wait!  TV stand!  Come back here!"

"Marching around issue" may come from the fact that Props' initial poses have been memorized...dForce Companion plugin can easily handle this "issue" since all unselected Props in the list will not be "simulated"... or you also can "re-memorize" Props' poses.

Another cons of "Start from Memorized Pose..." depends on the memorized pose... for instance if there's a significant rotations on figure's root node, in lots of cases one will get unexpected simulation results... So better wisely re-memorize an initial pose before simulation in such a case.

Thank you for all your answers, with this I must be good to make it work now! It's very appreciated  May you all have a very nice day!

I think what they're describing is actually an issue with a number of environments by (IIRC) Tesla3D that have keyframed animation on various components for no clear reason.
