VR 5.3 Project Build Package Failed

Hello! I am trying to package a VR project that I have been working on, but it is not packaging succesfully. I will leave the log and I will you brief what I have done.

  1. I got a template for VR from someone who made some tutorials, I only unzipped the file, launched the project and I packaged it (without me making any changes) and it worked, all good.

  2. I started to add an asset package from FAB and now if I try to package, it is failing. So before adding the asset from FAB, it was working and after I added it, the package failed.

Now, I am a beginner in development and I don’t know that causes this problem, but after I searched online I tought it may be the FAB plugin (I didn’t installed in the marketplace or does that even matter)? I saw that there are people who had problems with it so that’s why I am asking (I even deactivated the plugin from the project settings and still failed, :frowning:
Thank you for reading and reaching out!

Hello there @RaMb0RO1!

Welcome to UE! Checking through your full log, I see that both Cooking and Staging steps were succesful, meaning your assets were processed properly, no conflicts. The procedure fails at the packaging step, and the critical error shows up in the following line:

Failed to find value when parsing C:\Users\alexa\Desktop\Proba_Export_1\Proba_Export_1\Config\DefaultEngine.ini, line 117: r.Streaming.PoolSize 16384

This points at a syntax error in your .ini file, which currently contains the line like this:

r.Streaming.PoolSize 16384

The correct form should contain a = symbol, like this:

r.Streaming.PoolSize=16384

UE can’t parse that line, and the whole packaging fails. In order to fix this, simply navigate to C:\Users\alexa\Desktop\Proba_Export_1\Proba_Export_1\Config\, open the DefaultEngine.ini file a notepad, search the line including “r.Streaming.PoolSize”. and add the missing =. After that, save the file and try to pack again. It should now work as intended.

As for why this happened, it is possible that the FAB asset you added contained it’s own version of the .ini file, with the typo, and that’s why disabling the FAB element did not fix the problem. Hope this helps, and good luck!

Hello @brs-sebascova !
First of all, thank you much for taking time for responding, explaining and helping me, it means a lot :slight_smile:

Second, I understand everything you said and I have some questions:

  1. About the streaming pool size, I will put the “=” symbol but what I want to ask you is how what number should I put exatcly in order to reduce the stremaing pool size for the packaged project for VR? I saw that I need to put the VRAM in MB number, which in my case I have 16 VRAM and that means 16384 MB. Does this even matter for a packaged content?

  2. If it matters, should I put this command in the DefaultEngine.ini, or should I make a blueprint? (is that even possible :slight_smile: ?)

  3. About FAB, so in the future should I disable FAB plugin again for should I leave it just like it is?

  4. One more thing, does the scalability settings let’s say from Epic to Medium matter in packaged VR project, or they matter only in the Unreal Editor?

Thank you so much for time and responses @brs-sebascova and take care!
