@ (or anyone else), do you happen to know if the 4.20 FleX branch is capable of building installed (binary) builds? I seem to get some issues related to linker errors and maybe, just trying a clean build from scratch again and I’ll post the automation tool log when it’s done (if it fails again, of course). EDIT: So after testing it seems the DebugGame configuration on 's branch doesn’t seem to work properly not in terms of general functionality but just for making installed builds, enabling only Development and Shipping configurations seems to work fine, I did get some complaints about VS2015 compiled binaries but it all seems to work with the example flex project. ---

Are there any plans on adding support for diffuse particles to the Flex build? Or has anyone gotten to work and can give me some pointers on how to do it? ---

Hi everyone, I cant get unreal 4.21 to accept a .apx from hairworks. I’m not a programmer as I’m the modeler/animator so can anyone break it down for me how to force feed my hair file to unreal? Currently when I try to import it, it says .apx file types not recognized. Thanks in advance ---

> [@tfro19](#): > > You are , but the link is down. Can you re upload ? And maybe also give me a link to instructions of how to install a patch like ? You need your Epic account linked to your github account to be able to access any UE4 fork: [https://www.unrealengine/en-US/ue4-on-github](https://www.unrealengine/en-US/ue4-on-github) It’s also not a patch, it’s modified engine version. Meaning you have to build the engine from the forks source code and use that custom build to use these techs. ---

Currently when I try to import it, it says .apx file types not recognized. I don’t know much about HairWorks authoring but I think you still need to use matching HairWorks plugin on your modeling tool to export HairWorks assets. My 4.21 fork uses HairWorks 1.4. I’d start by looking how the HairWorks sample scene is setup and what kind of assets it uses. ---

I don’t remember if you can disable WaveWorks with some console parameter. I wasn’t aware of WaveWorks adding a cost unused though and I don’t really have time to investigate it myself now so I put out different branches with and without WaveWorks merge: (Blast, Flow, HairWorks, HBAO+, TXAA ad VXGI2) (same as above but with WaveWorks) ---

> [@AngeIV](#): > > branch is 25 commits ahead, 185 commits behind EpicGames:release. It’s actually not behind at all, it’s just that github doesn’t count squashed commits in case. Basically the commit ( merges the latest engine changes for 4.21 so you should be good to go. The reason I squash commits like is because if I just did a regular merges without squashing, it would spam the commit list with those changes instead so people wouldn’t know what actual changes the repo does (as the relevant commits would be mixed with the stream of other random commits). I recently redid all my physics branches so that I used only latest versions as base directly, for example and the mentioned are both in sync with 4.21.2 but github only reports the latter to be behind 🙂 ---

> [@AngeIV](#): > > How stable is build “as is” ?? Would love to try it. There can be side- from running custom repos like these, like mentioned in few previous posts the testing is limited. I mainly test that the repo builds on development conf and see that at least one sample project that uses each merged tech runs and builds fine on Windows shipping conf. If you look back of the comments of thread lately, few users have had different issues, one noticed that 4.20 repo doesn’t build on Debug conf, which I never tested myself so that slipped through. One user noticed WaveWorks giving a cost even unused on 4.21 so I just separated it into different branch now but I don’t have time to systematically analyze the these techs have for the stock ue4. In general the negatives should be minimal but things like mentioned can slip through and I give no guarantees these things work. I do try to fix all known build issues if I can but that’s also limited by my time to put into (I haven’t had time to check the 4.20 FleX on debug conf for example. It must be a trivial thing to solve unless it’s something Nvidia didn’t ship required binaries for from their side). ---
