Okay so, I have been using a cordon box around the map till now, I checked pointfiles and i remember last time i tried doing this and was actually not compiling due to leaks and stuff, there is a lot of weird stuff going on in my map, things like point files not pointing at the right things, apparentley a area portal not finding a portal or something. So here are the pictures, In the top image you see a point file i loaded from a previous version of the map, I checked my grids and the 3d view, it starts from the void and right when it touches the brush it stops there, I found a hat in side the brush and i moved it back up to my table, then i recompiled, now in the second picture the red line starts from the hat and goes up to the cubemap and just stops there, yes i checked the whole room no other red lines.. Now for image 2 which makes even less sense then the first In the top image I show you how long the line is, for 5 - 10 minutes i went around the whole line checked around form the top and to the bottom to the middle nothing. Then in the second picture I went in front of it and to my surprise it was just floating pointing from one spot to another spot floating in the void, clueless on how to fix it. I used the error checker and it told me i had a leak i went to the leak and it took me to where the second pictures leak is at. Code: entity prop_dynamic (-987.00 593.00 -27.00) leaked! Description: You have a leak. A leak is a hole in your map that exposes any entity in your map to the void (the black space outside your map). Then i scrolled down and saw this error Code: indportalside: couldn't find a good match for which brush to assign to a portal near (2560.0 4096.0 -367.0) 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. I went to the co-ordinates and it took me to a random spot into the void, behind me was a room and i checked around and i didn't see any leaks. So please you guys help me out here, I really need to fix this up so i can get V6 of my map out Thanks in advance to all who read or try to help. Edit: I removed the hats on the table which got rid of one red line, there still is that existing line that points to nothing and is very long, i compiled, So i have to fix this now because now this is happening without cordon box..
