Mod preview crash

In the editor, if I try to preview, a fatal error occurs and the kit crashes. Suggestions?

Can confirm I’ve experienced this crash on my end as well twice now

I’ve got a similiar problem.

My error:

I get this crash evertime I press play and when I try to start the ark dev kit through steam, it tells me this:
arkdevkitError.PNG

What map are you trying to load? And have you installed the latest Engine+Editor DLL’s from GitHub?

First I tried the test map. Then I tried the DinoArena. Neither worked. It seems I do not have the latest stuff from GitHub. I’ll download it and see if anything changes.

Getting the new stuff from GitHub fixed it. Yay

I’m having the same problem with the preview crashing. Installed the github files this morning. Crashes when I preview anything, including ‘The Island’. Same error code:

Fatal error!

I am trying to preview my own created level

Edit:
I am able to press play in the TestMap walk around and do stuff but when I create a new level place a Box and player spawn and press play. The fatal error occurs and the UE4 Editor closes.

Solution:
I finally found the solution !!
If u have the problem as well, search in the “modes” tab for a class named “Global_PostProcess_Blueprint” or just tippe “global” and it should appear. Drag and drop it to your level.
That fixed the problem for me. Now I am able to play without a crash :slight_smile:

Glad you got it working!
