Running a map with more will cause the engine to abort with the error message 'P_CreateTIDList: MAX_TID_COUNT (200) exceeded.'. Vanilla Hexen has a hardcoded limit of 200 things with a thing ID. Hexen-specific as other Doom engine games do not feature thing IDs. However the check for this is incorrectly placed, so instead of aborting when this limit is reached, memory will start to be overwritten potentially leading to a variety of other errors manifesting. The vanilla engine has a limit of 64 scrolling walls a map. The corresponding things still exist and will behave as normal, but will be invisible. Similar to segs, if more than 128 sprites are visible in a scene, they will not be drawn. Avoiding this one is as simple as making sure 30 moving floors cannot be active in separate sectors at the same time. Only 30 plats (sectors with moving floors elevators) can be active at once or the game will exit with an error. Hitting F3 will instantly move the player to the area where the highest visplane count has been seen.Īnother useful tool for pinpointing visplane issues is Doom Builder's Visplane Explorer plugin]. Hitting F6 in Chocorenderlimits can toggle between three different visplane displays, making it much easier to diagnose areas that are being split into an excessive number of visplanes. Heretic maintains the 128 limit, Hexen raises it to 160 and Strife to 200. Reducing the number of unique sector heights, flats and light levels visible from a particular scene will drop the visplane count. Unlike the seg limitation, which is merely cosmetic, the 128 visplane limit will cause the game to exit with an error.

Reducing the complexity of a map's architecture, so that fewer subsectors are required, is the best way to drop the seg count. This limitation was even lower in version 1.0 and HOMs could be seen from the outside area of E1M8: Phobos Anomaly.īecause segs are the result of running a map through a node builder, there is no way to directly control the seg count from a map editor. If the seg count in a particular scene exceeds 256, additional segs will not be drawn, which causes a Hall of Mirrors effect. Chocorenderlimits, a modified version of Chocolate Doom, can display the current number of these elements in real time while playing a level. Vanilla Doom has several static limits on various map elements.
