NVIDIA GameWorks Integration

[Ahri9Fox]

Is it possible to use Flex with the latest version of UE4(4.25.4)?
I compiled Flex and it uses the compiled version of UE4(4.19), I would like to work with Flex in the latest version of UE4.

Can I install HBAO+ plugin on existing ue 4.25 or 4.26 preview ?

[GGUMINGUUU]

Hi there, I am trying to create a custom built of Unreal Engine for my Studio and I want Gameworks Plugin to be installed there. I have downloaded Gameworks for ue 4.21 and I see there are plugin folders there containing Gameworks features. If I generate Visual Studio files from there and then rebuild it, will it install??

Anyone can help me on this issue and also I am willing to pay for the job done

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 this 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?

It's ok for now, I am just experimenting, but please let me know if it's ready!

[Jerry.Richards]

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

Just wondering if the build process is going ok for you.

My one gets stuck just after it tries to compile the Blast module.

I am getting these errors on packaging.

Anyone run into these?

formatc2013 glad to hear it Thanks for letting me know. . .

[formatc2013]

Not sure that this 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.

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 Are you running this from within the VS2019 command prompt?

Are you following the below steps?

1. Open VS2019 Command Prompt
2. git clone https://github.com/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?

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 this 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 this stage.

Unfortunately yes. The upcoming production ready Chaos API will be the official supported PhysX 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.
