A new version of Dark Physics has been released. Download it from your Order History. There is no installer at this point. All you need to do is copy the DLLs into your plugins-licensed folder and ensure you are using the latest Ageia runtimes.

The main changes are:

* you can now run the fluid demos in software mode

* a basic implementation of soft bodies is included along with a demo

If you have any feedback please post here. Ideally looking for issues where maybe something is broken or not quite working correctly. Thanks for your time.

Thanks, Mike.
The soft bodies look great. How does that differ from ragdoll or can it be used as such?

I never thought that I would say these words but those frogs are sweet

Regarding problems, similarly to the final version of beta 3(other previous versions of beta 3 worked), dynamic meshes are not being included in the physics simulation.

Theory is when you know something, but it doesn't work. Practice is when something works, but you don't know why.
Programmers combine theory and practice: Nothing works and they don't know why.

I've an issue with the Ragdoll example: the program crashes after a few seconds, this one: "Projects\Dark Physics\Demos\Ragdoll\Ragdolls".

Great job, Mike!

Is there any tutorial to make "tet" model?
Or plaese inform us about tet format. I really wanna design my original softbody model!

Mike with ragdoll demo if you try to run it using F7 step mode you do not even get the chance to do anything just pops up the MS error box.

Plus on the Fluid demo was the water suppose to fall over the edge of the object or a few points back. was as if there is a thin stripe across the object lets the water falls through that.

edit
water falls off in line with bottom edge of sloping box in demo and not the top one.

The frogs are cool but they could do with better collision detection. All fluid demos work, but they all seem to look like slim, is that how they should look?
a little glitch here and there with the fluid, like some small misshapen fluid partials.

works good anyway, And on my laptop thats saying something.

Am not sure what to download. I have some links, namely:

a) Download,
b) Download Physics projects,
c) Download update 1.01,
d) Download update 1.04 beta and
e) Download Dark Physics for Dark GDK

I do not have any other link, so am downloading the first one, so please advise.

May the 3d force B with U

You'll have to download the PhysX SDK. There you will find the PhysXViewer which allows the editing and export of .tet files for soft bodies.

@JDForce
If you have Dark Physics already installed, just download update 1.04 beta and copy the contents into your Compiler->Plugins-licensed folder. If it is a fresh install, then the sequence is a, c and d with b for additional examples.

Hmm... still pretty buggy, and now that guys' game is screwed.

IMO pop an installer up for this ASAP, so those who install it and have trouble with it like me and kaedroho can actually uninstall/downgrade the thing.

kaedroho you may now SCREAM!,

I just compiled this and it works ok in 6.8, unless your post was meaning some early version.

Do you are get the MS error box coming up each time you try to run it.

It also works correctly here, with the character controller moving and rotating.

Yippee,

Dark Physics works again – never did get the last version to work despite various downloads and updates.

Do get the same crash with ragdoll example as above.

Frog looks great – and can see fluid in motion for the first time.

Thanks for the continued support of a great product – by far the best add on I have bought.

When will we see DarkPhysx for GDK being updated?
The DarkDGK version still fetches and loads up the libraries PhysXCooking.dll and PhysXCore.dll from v2.73, and not the new nvidia v2.81 dlls

It didnt work for me at first and i downloaded latest PhysX and it worked! the problem in my game is the way the CC is structured. ive managed to fix the problem by removing jumping out of my game so i can restructure the character controller. Sorry Mike.

Mike, can you update the help files please.

those who know about ConEngine3, id just like to announce that ConEngine3 wont use Dark Physics.

Mike are the following command new ones? as they do not have any help files on them.
(some help files I found were there but had diffrent spelling to key word eg ragdoll as rag doll).

theres soo many undocumented commands. All the new raycasting, force fields, etc.

and mike how do i get metal? or is that cloth demo which is included with the Nvidia PhysX demos a scam?

First, thanks for the soft bodies.

I'm unable to run any of my programs with DarkPhysics straight off a CD-ROM. They run fine off the hard drive.
Is there a trick to it? do I need to include any dll on the CD-ROM?

Also, like Kendor, my dynamic meshes don't work.

Now you have to tell us how we make our own soft bodies.

I can see a file with the extension name "TET"

Tell use how we make that, and how the commands works please

Could the soft bodies be applied to fishes, and animated objects to give them a more realistic feel?

@bergice
get the SDK at
http://developer.nvidia.com/object/physx_downloads.html

after you install go to sdk\samples\executable and you'll find Physx viewer that lets you export tet files.

The Physx viewer loaded my converted .x object that had been made into an .obj object, but when I asked it to make a .tet .obj it went and crashed, and the files it made where .mtl.

liked to know if anyone else finds it not working, or something on my system is mucking it up.

At least it shows some demos on how some of the objects should do there thing.

Thanks, but could you add soft body to an animated marine animal?
So for example when it bumps into something then it is smooth and it moves like a fish.

anyone has managed to export a .TET file from physxviewer?
When I try to export TET file with obj, the physxviewer crashes all time.
Is it all because of my PC?

Take a look at the second post of this link http://developer.nvidia.com/forums/index.php?showtopic=1634&mode=threaded&pid=4023, (the user name is pure coincidence), anyone know if that option is plausable for DBP?

Ok this is really dumb.
sooo many things are broken

the competition is going to be a handout to whoever can get it working right!

sorry if I sound grouchy but are we supposed to make a soft bodies demo with frogs and and an Nvidia logo!?!

if not then we need PhysxViewer working.

Also I can't get fluids working yet see here:http://forum.thegamecreators.com/?m=forum_view&t=132327&b=30
