FAQ

Q: Can monsters crawl through the vents?

A: Yes! They all can go through the ventilation ducts like any other flooring!

Q: The performance is bad sometimes without Cullfactory, are you going to fix that?

A: These assets are game rips from Black Mesa so they are far more detailed than Lethal Company base assets and I have done what I can to optimize it. To help with performance I highly recommend CullFactory and PathfindingLagFix to play with this as it helps with it a lot for now.
