[Solved] Cannot create SoftObjectPath with short package name

Hello everyone !

I have an error in recent days that I can not fix. Here is the error in the console. Can someone help me or explain to me where this error comes from? Thank you.

ok, apparently the engine didn’t like it when I created a Sound Base variable called “StartSound”. I replaced the name and I no longer have the error.

Hi, could you tell me how you managed to know which variable was the one with an innapropiate name? I have the exact same error and i don`t know how you did it whit that error log.

Hi Geniusll, sorry for this late response. Error log doesn’t contain any information that helped me to resolve this issue. I’m simply created an empty map and drag&drop all class that i created in my project. When the error appeared I knew which class was the cause. It’s hard work especially for a big project but I couldn’t find any other way to do it. Hope you find the solution to your problem.
