The maps are ported by just changing vbsp version from 21 to 20. Soon I will let out the addon containing all maps But there is one problem. The whole map looks like after using mat_fullbright 1 command. I tried recompiling it in gmod’s hammer but it crashes at opening the vmf’s. Also something must be in the air, because physgun beam is like hitting something one inch from player’s eyes.
Here are photos so check them out - last one shows scale of lightmaps (mat_luxels 1).
