Eyo! Still working in Hammer, really enjoying the software at the moment. Currently, thanks to feedback on the workshop pages of Bunker and my newest map Prairie (of which will receive its own home here on TF2Maps), I'm currently working on optimization.
The brushes present in the Bunker should now all be details, meaning they all shouldn't render all at once, hopefully reducing any lag and rendering issues.
I do still plan on further optimizing the Bunker, and Prairie by extension, by introducing cubemapping. That should be taken care of in the next couple of weeks before my vacation.
Again, thank you for any and all feedback!
