How do i change the waveworks horizon color? I’ve tried everything and looked for documentation and couldnt find any. It’s driving me insane. I am trying to make a night scene and that is preventing me from doing it. Any ideas? A guy asked i see but he doesnt really explain how he did it. Anyone can give me a detailed explanation? https://gyazo/48641853dbc7cde89e6fb2fa5610b41b.jpg [https://gyazo/48641853dbc7cde89e6fb2fa5610b41b](https://gyazo/48641853dbc7cde89e6fb2fa5610b41b) ---

I’ll be joining the club of waiting for updated Gameworks integrations into Unreal, specifically WaveWorks, however, since WaveWorks 2.0 is announced I’d say they’re going to take that technology and port it to newer releases of Unreal. I was curious as to what we could expect, but all I could find was an interview with the developers of Atlas, the 3 things you should know article, and the info page about WaveWorks by NVIDIA themselves. ETA was soon back in early 2019, with no more information as of yet that I could find. Does anyone have more information on ? Looking to use WaveWorks in UE4 4.23 / 4.24 / 4.25… ---

4.1 + Nvidia Blast plugin bundled together with Unreal Engine 4.25 [https://github/dyanikoglu/Unreal…5-PhysX4+Blast](https://github/dyanikoglu/UnrealEngine/tree/4.25-PhysX4+Blast) Everything works without any problem so far, also you can change solver type from physics settings to 4’s Temporal Gauss Solver. I remember blast was having a terrible performance with 3.4, but I’m able to maintain solid 120fps with lots of destruction going on with 4.1 at the moment. v=3s4NB98v77Y Note: You need to build binaries from ThirdParty/PhysX4/BuildProfile\_Win64.bat, and you need Visual Studio 2019 as compiler/toolset to do that.

I can say it’s way more stable than 3.4. Temporal Gauss Seidel solver is . I’m not planning to open a PR soon, it’s kinda pointless, Epic is working on Chaos, and has no interest on anymore. Also, my branch doesn’t have proper support for other platforms except Win64. I need to sort out that first. ---

I recommend playing around with Epic’s new strands hair system, based on Chaos & Niagara. It’s way more promising. ---

For more realistic results with Blast, I recommend setting depenetration velocity to a value around 0.5-1.0, enabling Temporal Gauss Solver & Stabilization in physics settings. ---

Thanks, I’ve made those changes. Are you able to package the Blast Sample (shipping configuration)? When I try to do so the build crashes. I haven’t fully debugged why yet though. The build crashes in ActionGraph::ExecuteActions (I believe). ---

Ideally it would be nice to be able to use UBlastMesh on a skeletalmesh. You cannot right-mouse click on a SkeletalMesh and create a BlastMesh from it. Funny, though, UBlastMesh makes use of USkeletalMesh, USkeleton, and UPhysicsAsset: ```auto UPROPERTY(Instanced) USkeletalMesh* Mesh; UPROPERTY(Instanced) USkeleton* Skeleton; /* The physics asset to use for blast mesh */ UPROPERTY(Instanced) UPhysicsAsset* PhysicsAsset; ``` a modification I’m going to try if it hasn’t been done already. ---

[EDIT 0] I am re-cloning the repository now and I’ll repeat the process. Please give me a moment. [EDIT 1] I am trying to build the VS2019 solution now. Once I am able to test loading the NVidia sample project I will update you . For the record thus far I performed the following steps: Cloned the Repository Setup.bat BuildProfile\_Win64 GenerateProjectFiles Open the Visual Studio Solution (UE4.sln) Set UE4 as the startup project ```auto C:\Users\>d: D:\>cd repos D:\Repos>git clone https://github/dyanikoglu/UnrealEngine.git Cloning into 'UnrealEngine'... remote: Enumerating objects: 22, done. : Updating files: 100% (127484/127484), done.
