Working on a remake of my old multiplayer map that I released almost 25 years ago.
I only spent an hour and a half this stream, but I made a good amount of progress on the Marine Base.
Reworking the polies in the corridor corners worked for fixing my previous tri-to-quad predictability issues. Basically I split off the polies so that the vertices were doubled up. It's not really recommended you do this in general with meshes (you can get weird little artifacts "between the seams" due to floating point precision) but I don't think there are any issues in this case.
I suspect the Marine Base will be the most complicated area to texture. The Predator Temple will be easier, and the Alien Hive moreso. A lot of it is just trying to figure out which texture to use.
