I have a huge problem. the agent swarm is failing to kick off all the time. i have tried to build it in visual studio 2017 but the problem still remain. no i turn to you!! please help me contact me at dacsol@gmail.com with step by step tutorial on how to fix it. i need help to fix it soon as possible

If you select all your static meshes in your scene, and set them to Movable, does the lighting then build? If so I also get this problem sometimes. They only way I have found to fix it is setting them all back to Static again, then selecting random groups of meshes and setting them to movable until the lighting builds again. At some point it just starts working by itself from doing this. It’s tedious though. Try build lighting with all meshes set to movable, then set one as static and if it still builds it’s probably the same problem.
