You may have to build the UE4 project with your IDE. Alternatively, build using UnrealBuildTool with the commandline:
UE4Game

thanks

Tried to package the project from FILE - package but got most of the same errors .

Hey Ivaylo, your texture name is too long.

Hi, yeah i’ve fixed it and then collided head on with a number of problems, i am managing to fix them one by one… deleting temporary files, generating C++ code … its so complicated. I am almost done with this as the project starts to load in the local host but in the end it spits out this error:

Ok this is driving me nuts. I rebuilt the project. It has 0 errors, its clean and neat and light. 150 mb opposite to 500 mb on my first try. And i am stuck. After i package html5 for shipping and try it with the local host it just says 404 not found. And in the console not serving

I deleted .vs, binaries, build, intermediate, saved folders. Generated visual studio files from the uproject file in the explorer. Added c++ code to my empty(as in started empty) blueprint project. And dont know what to do now. I unckecked the .pak file export. tried with compression and without. What else can i check?

Still struggling… one time i was packaging for html 5 visual studio opened up and was doing checks and compiling and stuff for like 10-15 minutes. The other times it didnt open up… i dont get any errors while packaging… now i am checking emscripten … should i install the sdk? should i install python?

Hi, did you ever solve this last problem?. I got the exact same problem and ONLY when its a c++ project.
I’ve tried clean c++ ,fps and third with all default template. It always fails.
Blueprint-project always works in browser.
c++ projects won’t even launch from editor to browser.
I tried on home computer all new 1 week with clean install and i’ve tried from workstation at work .
I’ve tried visual studio 2017 and 2019.
I’ve tried UE4 v.4.21 and 4.22. 4.22 gives your exact error message, 4.21 gives a different number at the error report.
UE4 v.4.23 preview 4 did actually load in browser, but with horrible sound at max volume and black screen.Do NOT recommend headphones if you try.
I’ve tried with pak checked an not and i’ve tried shipping.
I’ve also tried upload and not with htmlhelperserver here: https://arcane-wildwood-26041.herokuapp.com
MSAA is off.
I’ve also tried creating a BP-project and then converting it to cpp ,but it fails.
Any help is appreciated as i need cpp project as base to develop further.
