I mean I’m not too familiar with git but why can’t you just fork from UE4 and create new file/upload your files as a new branch. I don’t personally use gameworks right now, I just didn’t want to see anyone get in trouble, but I also don’t want to see you waste hours rebuilding a repository if you don’t need too. Maybe has some tips. ---

> [@Gallonmate](#): > > Maybe has some tips. If the gitignore is setup right, all you’d need to do is to make your own fork, checkout 4.19.2-release and make a custom branch from it, then copy/paste from your offline version there and overwrite all engine files in that dir, add all changes to git, commit and if it’s fine, push to github. Sometimes these GameWorks branches don’t have all things setup for gitignore so it will also ignore some needed binary files but can’t tell how it was on VXGI. I personally avoid issues like these most of the time by doing the merges in place so those binaries will be included regardless. If some files do get left behind, you just have to manually edit the .gitignore. All being said… how on earth did you manage to merge VXGI 1 without git? There are tons of changes all around the engine for so doing it manually must have taken ages (plus it’s more error prone). ---

Ya it took several hours because 4.19 had shader and camera matrix changes from 4.18, so I had to change a few things around in the code. I think 4.20 has more of these changes so I am not sure about going any further with it. I even used Notepad++ instead of github lol. ---

@ahmadsy1 he was quoting my post from last month (I dunno why): > [@](#): > > The main with FleX is just the work amount, I haven’t encountered any showstoppers there, I just simply don’t have time to fix all the issues. Main thing that will keep people busy who will try to port it to 4.21 is the physics changes but you can find plenty of examples of the new physics interface on the code base ( is how I ported Blast to 4.21). ---

> [@ahmadsy1](#): > > @0lento_archive I tried to build. But, of course, i got so many stupid errors, which was never appearing in early versions. is expected as nobody has ported FleX fully to 4.21. If anyone wants to get it running, they need to first learn git and how UE4’s c++ engine code works and then spend from few days to weeks to fix it (depending on your skill level and how fast you work). ---

Hi , thanks for your amazing work, I’ve just cloned your repo (gameworks 4.21 at \*\*\*\*) and it seems to have some problem with sample scene of waveworks (the little scene, with a little tub. You can find attached the crash screenshot. I’ve also created an empty scene, and it crashed again in the moment I dragged WaterPlane\_Blueprint, so I suppose it’s an related to it. ![waveworks_4.21_bug.PNG](https://d3kjluh73b9h9o.cloudfront.net/original/3X/7/1/718a7d09b3ce2123bd5e0327105a5166c5bbdca5.png) [Previous page](https://forums.unrealengine.com/t/nvidia-gameworks-integration/16686.md?page=256) [Next page](https://forums.unrealengine.com/t/nvidia-gameworks-integration/16686.md?page=258)
