> [@Klikard](#): > > @0lento_archive Your 4.19 branch works like a charm currently no errors except wmf media but not really a problem.

The 4.19-Physics-GW branch adds that and the GameWorks magick. We can only assume he’ll do the same with 4.20! As Derjvyn replied, 4.20-Physics is indeed only some physics modifications I’ve made for UE4, it’s not related to GameWorks, I might add Blast to the Physics branch tho as it’s physics related. Also, the wmf media error should be fixed on the latest version of the 4.19-GameWorks repo 🙂 (it also wasn’t really an related to my GameWorks merge only, same happens on official 4.19.2 afaik, I pulled the fix from 4.20 for particular). ---

I just pushed Nvidia Blast (1.1.3) into my 4.20 physics branch: [https://github//UnrealEngi…e/4.20-Physics](https://github//UnrealEngine/tree/4.20-Physics) branch contains option for fixed timestepped physics (with interpolation) and Blast. I won’t add more tech to branch, just felt Blast suited that branch as it’s physics related. ---

Made a mini update on with a 4.20 GameWorks merge: [https://github//UnrealEngi…4.20-GameWorks](https://github//UnrealEngine/tree/4.20-GameWorks) It currently contains UE 4.20.1, Blast and Flow. Worth noting that I did make a bit hacky fix for Flow’s support, 4.20 added GPU indices on and I didn’t really want to spend too much time figuring out what Flow’s renderer code does there so I just made the thing use only first gpu index there, may potentially break things so I don’t suggest to try fork with enabled. ---

Thanks for all your hard work on - it’s much appreciated. I’m really eager to sit down and dig in with your physics branch, but I need to finish my major project before I get distracted yet again, haha. Keep it up! You are pretty much the only “goto” person with stuff, these days. I can’t help but be curious: are you using stuff in your own projects (or perhaps client work), or are you just being a diligent nerd? ---

> [@](#): > > I can’t help but be curious: are you using stuff in your own projects (or perhaps client work), or are you just being a diligent nerd? All those physics related things are based on custom work I did a long time ago, I published fixed timestepping for 4.15 and later made also contact modifications public for 4.18 so others may benefit from (worth noting that Epic exposed contact modifications partly now on 4.20 but you still need custom engine code to use it - which is what my current changes do now). Basically if you do custom vehicles or other advanced physics and/or physics networking, you often want changes like these to gain more control over physics. As for using GameWorks itself, I don’t really use it on any project atm, I do these merges for testing purposes only. I keep updating these repos nowadays mainly to stay on top of things: to know where GameWorks tech is going and to know what kind of structural changes UE4 has. > [@samrat333](#): > > please update hairworks in 4.20 thank you HairWorks is at the end of my list to add but I might check if it’s an easy add, no promises though. > [@rojo8399](#): > > @0lentoI’m not sure if anyone’s asked before, but do you have any plans to support VRWorks once it’s updated? I think someone has asked before. VRWorks is pretty much no-go for bigger merges like these, mainly because it alters rendering pipeline from many same places as these other techs and I don’t really have experience nor motivation for rebuilding the clashing parts. I’m fairly certain you could merge VRWorks with select GameWorks techs (like Blast, Flex, Flow) but these would need to be tested on case by case basis. And ultimately, I don’t have VR gear so I couldn’t even test if it works properly so that makes the whole process impossible from my end (as testing often reveals all kinds of issues and I can imagine part would be way more important when dealing with VR). ---

Added TXAA and Volumetric Lighting to [4.20-GameWorks merge](https://github//UnrealEngine/tree/4.20-GameWorks) It now contains UE 4.20.1, Blast, Flow, TXAA and Volumetric Lighting. I spend a long time yesterday porting FleX as well but while I got it to compile, it still crashes on play so I’ll keep investigating if I still can fix it (I’ll not include it at state). ---

> [@samrat333](#): > > 4.20 hairworks ???
