| Summary | 0000464: portal system acts strangely on very large maps. |
|---|
| Description | I'm not quite sure how the portal system is handled in the engine, but I can safely say that it'll need some work. In my big mall map, I utilize the portals to project a roof on top of the mall to add in detail. Most of it runs smoothly -save for minor framerate issues. However, depending on where the "roof box" is positioned, one part of it will always act strangely. If I move it too far out, then the sky either won't render at all, or the engine will crash out saying it cannot allocate 3 billion bytes of memory or something like that.
My mall map faces the most problems in QZDoom, running at 4 fps. And the roof acts very strangely, seeming to conflict with the 3D floors placed throughout.
The bug is also present in GZDoom, but acts differently. On GZDoom, the map runs much more smoothly, but still acts strangely with the portal that projects the roof. As far as I am aware of, the map doesn't crash on either of these platforms. |

The following link takes you to the map, which although out of date, features the bug. To reproduce, simply just run around the parking lot of the mall (specifically by JCPenney), and then look at JCPenney. Depending on where you look, different parts of the roof will act strangely. |

| Additional Information | If you wish, PM me on the forums and I can provide you with a more up-to-date version of the map.
I would've uploaded here, but unfortunately, the map is much too large to allow such a wad. |
