Summary

This has happened to me every day for 4 days in a row!
I keep getting cook error, I’m using village template adding a new level then making the game, it will work and push changes fine all day when i return the next day it will break and give me cook error, i cant find a way around this other than making a new Village template project and copying as much as i can to the new project. This is so frustrating and wasting my time! i tried to fix it for about 7 hours yesterday, there is no information how to fix this or even diagnose it.

I had some errors with the boardwalk ruby fbx but this is not causing the cook error as i have validated / re imported them and those errors are now gone, but the cooking error still remains

4

For some reason after adding a new level and then going back to the old one and also changing the map data default map as the one I want to play and map data to none, it somehow worked and I can continue. I believe that the issue will happen again after I close the session tonight but i will update the issue tomorrow if this happens.

COOK ERROR BACK AGAIN! - so I worked on the game for a few hours and it has been working fine. the last thing I did was duplicate a bridge which is a referenced asset in the project and landscape paint. I’m not sure what to do again. I’m pretty sure its to do with the referenced assets at this point. I’d love some more advice on this as I’m currently unable to continue!

6

Someone please help me i just want to make my game :cry:

7

@Flak is there any advice please? or anything I can do to get more help?

8

so it appears from the output log and this error I’m not allowed to edit the referenced project [village template]

as mentioned before I’m using the waterbody material instance to change how the river looks, and i also copied the Pidgeon vfx from the main level into my own level

LogValkyrieRequestManagerEditor: Failed to get extended error information for cook job:feb5ce34-ab20-43e9-8b0a-4297d937d268, error:Failure ErrorCode=errors.com.epicgames.content-service.operation_forbidden, Message=This request is not authorized to edit referenced project, Raw={

im confused if this is the case because on this page it says i may “modify as you see fit”

I’ve now wasted 10 hours trying to get this to work, is there any support i can get or anything i can do to make this work? I’ve put alot of time and effort into this project and am not sure how to get support? the last person who posted these errors (i found by googling) has been un answered for 30 days?

We’ll get someone to take a look.

Thankyou Flak im pretty sure im just not allowed to use any referenced assets,

The ui’s from user interface template migrated into village template
The pidgeons, winds and water material instance from village template
