(2019-02-26) Sega Saturn Z-Treme engine

Update from last month, just showing the new engine (now a BSP tree based engine - which was a LOT of work). First, sorry for the video quality and for how dark the map is, I didn’t spend much time on it as it’s just a test map, but other textures would make it way better as the current ones are dark. The new engine uses a compressed potentially visible set (PVS) for occlusion culling. The compiler creates portals and these portals are used offline to calculate the visibility. It reduces overdraw a lot,
