UnrealJS failed to load because V8 could not be found about unreal.js HOT 14 CLOSED

I've also tried renaming v8 to V8 (shouldn't matter, windows).

from unreal.js.

Prebuilt binary was not built against official release from epic. Could you post 'output log'?

from unreal.js.

Where do I find this log? There is:

AppData\Local\EpicGamesLauncher\Saved\Logs

However it doesn't seem very useful: http://pastebin.com/LYJMduDp as no instances of UnrealJS show up.

from unreal.js.

Log you posted was not generated by UnrealEditor. I think the right location is appdata\local\unrealengine\4.10\saved\logs.

from unreal.js.

Here we go:

The relevant portions:

Was something else supposed to be extracted there?

from unreal.js.

Did you extract prebuilt binaries into /engine/binaries/?

from unreal.js.

Ah, I did so and now the log states:

It looks like I should rebuild the binaries from source?

from unreal.js.

It seems necessary to recompile plugin as you mentioned.

from unreal.js.

Current prebuilt binary isn't compatible with stock 4.10 build.

Prebuilt binary was build with local build, so API version was zeroed. Sorry for inconvenience; this is my first public plug-in build.

from unreal.js.

Prebuilt plugin has been uploaded again. I setup new VM, installed fresh MSVC2015, downloaded stock 4.10 and rebuilt UnrealJS. So I hope that this release will just work for everyone.

from unreal.js.

This is awesome, thank you for the rebuild!

from unreal.js.

Nako, according to https://github.com/ncsoft/Unreal.js/releases the last built is still 4 days ago. Is that correct?

from unreal.js.

I uploaded new zip file, but it seems that the release date didn't changed.
