Just the substance plugin. Edit: I’ve disabled substance and trying to package again. Edit 2: The same log occurs again. -Orfeas ---

Disable the substance plugin and delete your Intermediate and Saved folders and then try again. Provide me the logs after you’ve done that, to see if it changes. Thanks! ---

Could you try to delete the I:\Epic Games\4.13\Engine\*_Intermediate\Build\HTML5.emscripten_\* folder from your Engine? (only the bold part) Then go ahead and re-verify your version of the engine and try to package again, upload those logs as well. Also, let me know whether or not you’re using a Source or Binary version of the engine. Thanks! ---

Hello again, I’ve tried your suggestion and the same error [occurs][1]. Moreover, I deleted the entire version of the engine and re-downloaded it through the launcher but again, the result is the [same][2]. I’m using the Binary version of the engine.

Try removing the HTML5 target from the project you’re trying to package. The plugin should compile. ---

Hello, just to clarify, I’m trying to package a plugin that I have created and not my game. I disabled the HTML5 option and I’ve tried to package my plugin again but the same error [occurs][1]. I’m not sure if this means something, but when navigating to the export folder, inside the Intermediate-\>Build sub-folder, a folder named HTML5 has been created. Is there a that the export process works fine but a “false” error to occur? Thank you in advance, -Orfeas [Disabled HTML5 package option - Pastebin.com](http://pastebin.com/FTB1ZGeZ) ---
