I had missing polygons and several other artifacts before this but after i tweaked my map and made some ends meet properly it fixed all those problems but this one remains persistent no matter wat i do!!! Someone plz help me out here!
(And by the persistent artifact i mean the gradiating black on the corner of the wall!)
You provide far too few information, the mesh is not available, the picture is too dark to see anything. I guess many people would know a solution if they had a better start
Put the texture in \Textures\base_wall\ folder this will make it work! And i have setup the spawn points so it will run in q3 and the texture is in q3's so no need to set it up!
What do you mean done the light mapping rit??? I have tried changing the pos of the lights and tried compiling the bsp using several options in gtkradiant but none work!
