Most common map compiler errors QBSP
List of most common warnings and errors you can get while compiling a map.
Reached occupant at
This means you have a leak. Some entity touching the void. All entities must be sealed inside the map.
Healing degenerate
Bad rotation of the brush and/or some vertices not on grid.
Bad surface Extents
This means you compiled the map using an incorrect texture file. Possibly you are compiling someone else's map.
Point off Plane,
Warning: CutNodePortals_r:newportal was clipped away,
Brush with duplicate plane,
These errors are usually caused after carving that you can safely ignore. Sometimes you can load the .map into Worldcraft and export it back to a .map file and solve the problem. If not you should delete the brushes causing the error (which will be the ones affected by your latest subtraction) and try again. Trying a different method of subtraction might help. Check the section in Tips/trick on "carving cleanly" for some hints...
AddBrushPlane: numbrushfaces == MAX_FACE
You've made a brush that has too many sides for qbsp to deal with. There are recompilations of qbsp (qbsp256 is one) that have upped this limit significantly.
Mixed face contents in leafnode
This is the result of having two or more of the 'moving' textures touching: Water, lava, slime, teleporters and sky are all examples.
Leaf with too many portals
Without getting technical, it means you have a small area of your map that has too much detail. You can modify the source code to vis to deal with it - but chances are you're probably making something that Quake wouldn't handle well. Try making it simpler.
Leaf portals saw into leaf
For some reason a portion of your map was created that VIS can't properly deal with. It's probably a small area with lots of complex detail. Or, you may have run vis with the -fast option. Running full VIS might solve it.
Error:CanonicalVector: degenerate
The great mysterious error. Several people have had the misfortune of seeing this error and yet none of gotten a clear answer of what the problem might be. I've talked with a number of professional editors and they are all stumped. It's been said that John Carmack, when asked about this error, would get a scowl on his face, mutter something under his breath, and stalk off.
WARNING: too many light styles on a face
Each face can only have 4 different lights hitting it at once .. more than this produces this warning. It's ok to ignore unless you start seeing lighting weirdities in your map, in which case you should rearrange/minimize your light sources.
WARNING:brush plane with no normal
Somehow qbsp doesn't think it can draw a line perpendicular to the plane in question ... go back and redo the section that started causing this warning.
Portions of the map "grey out" when viewed in quake.
You've created an area with too many faces for Quake to draw at once. This will happen with an un-vis'ed map. If the map is VISed then the area needs to be simplified. This will happen often in large open areas or areas with a lot of extra detail. Check out tips/tricks sections for help with keeping your r_speeds low.
