How to make UnrealEngine-HTML5-ES3 Support WebAssembly 64 bit? And run normally under multithreading. #165

freebirdxxc · 2024-06-13T07:44:48Z

How to make https://github.com/SpeculativeCoder/UnrealEngine-HTML5-ES3 Support WebAssembly 64 bit? And run normally under multithreading.
I forgot my password for my previous Github account and registered a new one, but I am unable to access the Github. com/SpeculativeCoder/repository (my previous account was fine, but the new one is not).
So, I can only send the question here. Please ask experts who are proficient in this area to provide answers. Thank you!
Regarding 64 bit and multithreading, it is currently a major bottleneck that restricts us from using UE to package HTML5. We have been studying it for a long time, but we have not been able to find a good solution.

wapollo86 · 2024-06-14T01:57:47Z

I also have the same problem

kevinclv · 2024-06-14T03:53:56Z

This 64 bit is still a bit difficult, it is said that emscripten.org has not fully supported it yet

honeymarkery · 2024-06-14T05:31:03Z

Is the 4GB memory in the browser not enough? Why do we need 64 bit? @freebirdxxc

freebirdxxc · 2024-06-14T05:34:02Z

Is the 4GB memory in the browser not enough? Why do we need 64 bit? @freebirdxxc

For some applications of digital twin visualization and metaverse, 64 bit is necessary, otherwise it cannot truly be commercialized. Because these applications typically require 8-15GB of memory.

david1010xu · 2024-06-14T08:37:24Z

This 64 bit is still a bit difficult, it is said that emscripten.org has not fully supported it yet

As long as some code in WebAssembly is modified, it can support 64bit very well. I have already implemented this and also achieved stable 64 bit operation under multithreading

david1010xu · 2024-06-15T12:48:09Z

Your problem has also troubled me for a long time. After several months of unremitting efforts, I have solved the two problems you mentioned and also supported the WebGPU interface. Currently, I am porting code to UE5.4 and believe it will be completed soon.
UE4.27.2 packaging HTML5 now fully supports WebAssembly 64 bit and runs very stably under multithreading. I have supported both WebGL2 and WebGPU.
1.WebAssembly 64 bit, which allows packaged HTML5 programs to break through the limitations of browser 4G. It can support up to 16GB of memory access, which is sufficient for browser programs.
2.The management of Wasm in multithreading is relatively complex. To save space, I won't go into too much detail here. I have written the code as a batch executable program.
3.Regarding the support for WebGPU, it is currently possible to achieve the normal operation of various shaders in SM5, and the running effect is almost the same as the packaged Windows version
This Setup program contains the diff file of the source code and hundreds of related modified .h/.cpp files.
At the same time, I also included some of the 64bit compiled code in this batch executable program.
We encountered many problems in the process of researching UE packaging HTML5, and the reason is actually that the authors of SpeculativeCoder provided pure source code without many automated update operations, which led to a bad initial experience for us and many people giving up. In order to avoid this situation from happening again, I decided to package all the tedious configuration work into batch executable program. Of course, I still provide you with the all source code, but you don't need to perform complex configuration operations.
For the convenience of everyone, I have compressed the code from the GitHub repository along with the program I am currently creating and setup.bat into UnrealEngine4.27-html5-64bit-Md-WebGPU.zip,
The next steps are:
1.Preparation: Install Visual Studio 2022 and Windows SDK 22621 (if not this version, compilation errors may occur!)
2.Extract UnrealEngine4.27-html5-64bit-Md-WebGPU.zip.
3.Execute Setup.bat under the root directory inside,Run Setup.bat with a super administrator (must be super administrator! )
4.Setup.bat will wait for a period of time based on your computer configuration,After 5-10 minutes, the code in UnrealEngine4.27-html5-64bit-Md-WebGPU.zip will be updated, and the 64 bit and multi-threaded code that was modified for me has been merged.
5.After starting GenerateProjectFiles.bat, the solution project file for UE4 will be generated
6.Next, start running Engine\Platforms\HTML5\HTML5Setup.sh, which will automatically download emsdk3.1.60 and compile all third-party libraries for 32-bit and 64 bit. This process may take 4-6 hours depending on your computer's configuration
7.Open UE4.sln in the root directory using Visual Studio 2022, set UE4 as the active project in the opened solution directory, right-click on the project, select Build from the pop-up menu, and start the lengthy compilation process
8.Compile Programs
9.Create a new third person game project to start packaging. In the packaging project settings, please select the HTML5 tab, check WebAssembly 64Bit Support, check Multithreaded Support, check WebGL2 or WebGPU
10.Chrome browser is recommended and currently supports running packaged programs without adding startup parameters, as I have automatically corrected the startup environment of Chrome in EXE.
If you encounter any problems during the configuration process, please send me an email. I hope it can be helpful to you. Thank you!

freebirdxxc · 2024-06-17T03:36:53Z

@david1010xu After a long compilation, it finally started running and the WebGPU supports great results! I also tested that it can support 15.8GB of memory in 64 bit and multi-threaded scenarios!
Thank you very much for solving my major work problem. I don't know how to give you a reward. Thank you for your hard and productive work over the past few days

@kevinclv Batch processing went smoothly on my end. Have you ever modified any code on your end? After zip decompression, do not modify anything and let it batch process on its own.

kevinclv · 2024-06-19T08:34:05Z

Yes, I made some modifications to the configuration myself, redone it, and now it's resolved. @freebirdxxc Thank you!

I will now share the performance of HTML5 in the packaged UE5.3 project.
Select the Hillside architectural visualization project in the Unreal Mall and create a new project for UE5.3 version. After the project is opened, use the downgrade tool to downgrade it to UE4.27 version and then merge it into the BattleRoyalIsland project. Finally, package the project as an HTML5 version using tools that support WebGPU through UE4.27.

For those who need 5.4 support today with WebGPU, multi threading, SIMD and memory64. Check out SimplyStream, we now have an always free tier. We also have so much more than just WebGPU, like an automatic project optimizer, free hosting, webm playback, binary optimizations that can trim the size of your project to under 7mb compressed. There are many components that go into making large graphically rich unreal experiences in the browser possible and webgpu is just one part of that.

For the convenience of everyone, I have compressed the code from the GitHub repository along with the program I am currently creating and setup.bat into UnrealEngine4.27-html5-64bit-Md-WebGPU.zip, The next steps are: 1.Preparation: Install Visual Studio 2022 and Windows SDK 22621 (if not this version, compilation errors may occur!) 2.Extract UnrealEngine4.27-html5-64bit-Md-WebGPU.zip. 3.Execute Setup.bat under the root directory inside,Run Setup.bat with a super administrator (must be super administrator! ) 4.Setup.bat will wait for a period of time based on your computer configuration,After 5-10 minutes, the code in UnrealEngine4.27-html5-64bit-Md-WebGPU.zip will be updated, and the 64 bit and multi-threaded code that was modified for me has been merged. 5.After starting GenerateProjectFiles.bat, the solution project file for UE4 will be generated 6.Next, start running Engine\Platforms\HTML5\HTML5Setup.sh, which will automatically download emsdk3.1.60 and compile all third-party libraries for 32-bit and 64 bit. This process may take 4-6 hours depending on your computer's configuration 7.Open UE4.sln in the root directory using Visual Studio 2022, set UE4 as the active project in the opened solution directory, right-click on the project, select Build from the pop-up menu, and start the lengthy compilation process 8.Compile Programs 9.Create a new third person game project to start packaging. In the packaging project settings, please select the HTML5 tab, check WebAssembly 64Bit Support, check Multithreaded Support, check WebGL2 or WebGPU 10.Chrome browser is recommended and currently supports running packaged programs without adding startup parameters, as I have automatically corrected the startup environment of Chrome in EXE. If you encounter any problems during the configuration process, please send me an email. I hope it can be helpful to you. Thank you! My email: [email protected]

Is there any chance of this to be upstreamed like SpeculativeCoder's fork? Also, was the PhysX source also patched during build? I tried compiling SpeculativeCoder's fork with wasm64, went ok on my end but when it came to packaging a test project, I've seen PhysX issues.

Your problem has also troubled me for a long time. After several months of unremitting efforts, I have solved the two problems you mentioned and also supported the WebGPU interface. Currently, I am porting code to UE5.4 and believe it will be completed soon. UE4.27.2 packaging HTML5 now fully supports WebAssembly 64 bit and runs very stably under multithreading. I have supported both WebGL2 and WebGPU. 1.WebAssembly 64 bit, which allows packaged HTML5 programs to break through the limitations of browser 4G. It can support up to 16GB of memory access, which is sufficient for browser programs. 2.The management of Wasm in multithreading is relatively complex. To save space, I won't go into too much detail here. I have written the code as a batch executable program. 3.Regarding the support for WebGPU, it is currently possible to achieve the normal operation of various shaders in SM5, and the running effect is almost the same as the packaged Windows version This Setup program contains the diff file of the source code and hundreds of related modified .h/.cpp files. At the same time, I also included some of the 64bit compiled code in this batch executable program.

@david1010xu we're working on https://wardawgs.io , I'll be glad to test WebGPU for our case, as we're also moving to support multithreading :)
