How do I get the Stack O Bot Sample working? The main map will not open.

Development Getting Started & Setup

Each time I try and open the Stack O Bot main level it gets stuck opening the editor and freezing, even before I make any changes to the project. I can open the main menu level though. I have deleted and redownloaded the whole project 4 times now and have tried to delete the DerivedDataCache folders for both the UE folder and in the project folder.

Hey there @WolfRose1! Are your resources (CPU, GPU, or Memory) maxing out when this occurs? Where does the log itself stop (found in your Project/Saved folder)?

It looks like it never maxed out but it did go into Suspended status on its own.

I narrowed down the log to just when I was loading the map and made sure to change my windows username in the log for privacy purposes and attached it below. I tried increasing the geometry shader allowed memory size but it made no difference.

It seemingly freezes during the distance field building portion of the load. Distance fields shouldn’t be timing out, but if they do it should A report it but B failsafe out. Swap down to DX11 RHI and see if it goes further, it might provide some insight.

Unfortunately, that made no difference. I also tried verifying the UE editor files, did a fresh install of the editor, and looked in the HLOD and saw some negative values and used the arrow on the right to reset them to their default. I did an additional test of whether it loaded after each change with little to no change in the logs.

I even went to the Level Instance folder and was able to load each individually, as well as play the game map from the Main Menu Level.

SCRATCH ALL THAT: my antivirus Avast was apparently in silent mode and blocking some of the exes that Unreal was using without notifying me. :woman_facepalming:

Thanks for the update! It’s actually rather common for antivirus software to interfere with the engine, the build processes, or even some plugins that use Node.

A TLDR for those referencing this later:

A large map wasn’t opening because antivirus was blocking CompileShaders and Intelibuild. Placed the UE5_6 (or the current version your working with) and the Intelibuild folders on your antivirus’s exception list.
