@formatc2013 Are you able to start fresh?  
My suggestion is to use the command prompt and follow the same steps noted above.

Forgive the dumb question: are you using VS2019?

I will do a fresh start as I am back to my workstation in the next couple of day, and update you!

Edit1:

when running the setup bat file I am getting message on screen:

I am sorry. I should have looked at your output log better. The error is that it cannot find CMAKE or a file cmake is looking for:

```auto

ERROR: Failed to start local process for action ("The system cannot find the file specified"): cmake

```

From a command prompt would you please verify that CMAKE is installed and what version it is:

```auto

C:\Users\>cmake --version
cmake version 3.18.1

CMake suite maintained and supported by Kitware (kitware/cmake).

```

Another thought, CMAKE typically is installed with VS2019. You can verify that by looking at the individual installed components.

More importantly though, given the path requirements, you should be able to run the cloning, setup, buildprofile, and generate project files all within the Visual Studio command prompt.

Using the VS command prompt I was able to clone, run Setup, run BuildProfile\_Win64, and run GenerateProjectFiles

```auto

git clone https://github/dyanikoglu/UnrealEngine.git

cd UnrealEngine
Setup

cd Engine\Source\ThirdParty\PhysX4
BuildProfile_Win64

cd ../../../..
GenerateProjectFiles

```

After opening the Repos\UnrealEngine\UE4.sln file you may have to set the startup project to UE4, and press F5 to kickoff the build and debug session in Visual Studio.

is actually something I want to do too. To use Waveworks in UE4 v4.25. is the most I’ve found in regards to a download but I don’t know if it’s usable or not.  
[https://developer.nvidia/waveworks](https://developer.nvidia/waveworks)

There’s literally nothing outside of a few videos for the software and I really wish both Epic and Nvidia wouldn’t be so quiet about . While UE5 was announced, there’s no release date that I’ve seen for that so right now UE4 is all we have to rely on.

Have you heard or seen anything new about ?

I can’t even find Waveworks 1.0 for UE4 v4.25. The last version on Github is 4.19 and all of the links previously given for a more updated version are invalid/dead links now. I am at a literal dead-end. So I am hoping someone knows \*\*something \*\*about .

Epic never made any commitment to these things becoming a proper part of UE4 and Nvidia look to have lost interest too. So in my book the sensible approach for future projects is to assume stuff is dead, I’m certainly not basing a single future plan on any of these things, even though I was a fan of FleX and Flow. Obviously there are exceptions for certain project scenarios but its a world of pain trying to keep old versions up to date with modern UE4 versions so I’d rather give up at stage.

Unfortunately yes. The upcoming production ready Chaos API will be the official supported replacement for physics simulations inside Unreal Engine 4 and 5. And that’s it. Then on the marketplace there is a seller with its own limited physics simulations API, maybe others will follow. But Chaos API will be the new standard.

@formatc2013 Are you running from within the VS2019 command prompt?

Are you following the below steps?

1. Open VS2019 Command Prompt
2. git clone [https://github/dyanikoglu/UnrealEngine.git](https://github/dyanikoglu/UnrealEngine.git)
3. cd UnrealEngine
4. Setup.bat
5. cd Engine\Source\ThirdParty\PhysX4
6. BuildProfile\_Win64.bat
7. cd …/…/…/…
8. GenerateProjectFiles.bat

Of course if you are failing at step 6 then it is of no value to continue on.

Would you please capture the complete log, if you can, to a text file and attach it to your reply.

Note that you do not need the .git on the URL or the .bat filename extensions but I left them there for posterity sake.

The last time I tried I used the command line except for cloning the repo, than got stuck at step 6.

AFK at the moment, once back at my workstation, I’ll try doing all in VS cmd.

Just wondering how is running it from the VS command line different from just running it using the icons or any other command line?

Not sure that will help with what you are encountering but. . . I believe Visual Studio command prompt will set the path and environment variables that may be of help.

```auto

PATH=%PATH%;etc. . .
SET KEY=VALUE
SET KEY=VALUE

It is up and running now. All I needed was .net 4.6.2 targeting pack in VS.

@formatc2013 IIRC, Debug packaging was the only version that worked for me. I did run into the same you are seeing. is from memory and I would have to verify it. If you are planning on releasing from branch I can invest some time to see if I can resolve the(s) but there are no guarantees.

@formatc2013 Actually, at the moment I am working on my own editor and game engine. Basically creating a product to compete with 3dsMax/Maya and UE4/5. I am offering my help since is somewhat fresh on my mind, and it makes use of NVidia codebase (I love NVidia and have used their products for years). I cannot spend too much time on it but if it is something that you will use then I’ll take a quick stab at it. . . but offer no promises. Some of the bugs can take hours to track down.

That sounds like a daunting task. Are you working on it alone?
