I recently started experiencing a build failure. Any help would be appreciated. I haven’t changed windows, Visual Studio, or anything major in the project that I can think of.

Here is my very short log.

This is the entire log.

I did a clear log … then a cook.

Hello ,

Could you upload the entire log in the form of a text file? The cause of the failure doesn’t seem to be present here.

I see, I had assumed by the way you had worded it. There does seem to be one error that stands out but can mean a multitude of things.

“Exception in mscorlib: An item with the same key has already been added.”

There has been a report of the Substance plugin causing this issue. There was also another answerhub post in the past of someone having similar issues. Can you take a look at this post and see if any of it may be helpful?

I sure will. Thank you.

I did recently install the 4.10 version of the substance plugin. (in fact this occured between now and the last time I was able to cook/package my project).

I don’t understand why the heck my project requires the substance plugin at all. But thats another issue.

Have you had any success trying those methods ? As far as the substance plug-in goes, my experience with it is that it’ll give you the message saying that the Substance plugin is required if the project was ever launched once with it enabled. Hitting “No” will still start the project and never seems to cause any issues but if you download it, you should be able to manually disable it in the Plugin settings to avoid this in the future.

I did try them and it didn’t change anything. So far the only thing I have been able to do was to completely rebuild the project and manually copy blueprints from one project to the other.

The new project builds just fine with all of the old blueprints copied over.

As far as the plugin … clicking no does let you proceed with loading the project, but it also pops up a notice to the testers asking them to install the pluygin. They have to be instructed to click no. Which is easy enough … but it shouldn’t have to be that way. There should be a way to remove the plugin requirement for a plugin that isnt actually used in this project.

Thanks for your help. I’m still diging through all of the content in the original project trying to figure out what it won’t cook or package.

Referring to the Substance problem, when you open the project in 4.10, it should give you a message to disable the Substance plugin if you wish, this may not occur if the project was converted from an earlier version though as I know this wasn’t the previous behavior. If that doesn’t work, you can right-click the .uproject file and open it in Notepad or Notepad++ and change the “true” in the following lines to “false”.

“Name”: “Substance”,
“Enabled”: true

Sweet. That’s great info . Thanks I’ll try that.

We haven’t heard from you in a while, . Has removing Substance from the project helped at all with this issue? If not, please let me know if there have been any changes. In the meantime, I’ll be marking this issue as resolved for tracking purposes.
