I'm in the very early stages of an arena map (a small one) and I'm simply laying out the measuregeneric textured, power-of-2-friendly, brushes to represent buildings. I haven't reached lighting stages and the most complicated part of my map is a group of hollow blocks with windows and doors. So... why is portal flow taking 800plus seconds? The rooms are pretty small and it doesn't seem like I have enough brushwork to worry about func_detailing, areaportaling, or hinting. I don't remember compiling taking this long on other mapping experiments I had created prior to this project and they were far bigger. I think these issues came up around the time a put in a skybox, if that is even relevant. If anyone has any idea what could cause a small map in the most early of stages to experience seemingly long portal flow wait times I'd love to hear it, say thank you, then press the button to seal the deal, even. I'm sure it would be a nice moment and everyone would feel better for it. Or maybe it's possible that I'm just being impatient?
