While I was compiling my map I saw in my compile log that my map is leaked, the wierd Thing is that the pointfile is going throught solid walls (no, their not func_detail). The Position of the leak was also changing after I recompiled the map and recreate the brush were the pointfile went through. I checked the compile log on interlopers.net but the only thing insteat of the leak was: Spoiler: Problem findportalside: couldn't find a good match for which brush to assign to a portal near (6656.0 4096.0 960.0) Description: This error is usually followed by something like this: Leaf 0 Contents: (may vary) Leaf 1 contents: CONTENTS_SOLID (may vary, e.g. CONTENTS_WATER) viscontents (node 0 contents ^ node 1 contents): CONTENTS_SOLID (ditto) This means that none of the brushes in leaf 0 or 1 that touches the portal has CONTENTS_SOLID Check for a huge brush enclosing the coordinates above that has contents CONTENTS_SOLID Candidate brush IDs: [none or more brushnumbers] Usually, this error is caused by a leak, so fix it if it is. If it isn't, there is a (group of) brush(es) that is/are giving vbsp.exe a hard time to figure out your level. Apparently it cannot determine the boundaries of a certain portal. Maybe there is a large brush covering the area, maybe the area is just to complicated for poor vbsp to figure out. I don't know the details but usually turning entities to world brushes or vice-versa helps to fight the problem. Hell, just cutting a brush in two once helped me fight this problem. Solution: Find the given coordinates (or if a brush number is given search for the brush number) and see what you can do to to simplify the area (like turning brushes to func_detail). You should also check to see if the brushes are overlapping at any point. but when I go to the coordinates that are in the problem Report I end up outside the map where nothing is(also no center of an entity). What can I do tho solve this?
