Lightmap error in game engine

[UK_Karlos]

This problem has occured when i try and run my map any segestions

 

[blackflag486]

humm... I don't know, could be that the texture is messed up on the face

 

[UK_Karlos]

Could this error happen if a light source is in a very small area because i have 3 lights that are inside the HEV_Suit holder. when it opens 3 lights turn on. Or can u place lights anywhere

 

[UltraProAnti]

well i can't help noticing the dimensions of the lightmap its referring to are not powers of two...

 

[UK_Karlos]

Could u elaborate on what ur trying to tell me as iam not much of a techno jargon guy or skilled maths. is it to do with something about the lights i have in my map or is it a certain texture that carnt reflect light. I have no errors in my map so it carnt be any faces, the error occurs when i load the map (bsp) after i compile it and theres nothing in the log that tells me there is an error. but here is the lastest compile log.

My oh my.... compile errors all over the place...

After consulting http://www.interlopers.net/errors/errors.php?page=checklog
I find this

"nodraw on terrain surface
you aren't allowed to have the "tools/nodraw" texture one a displacement. So find this displacement (can be hard, you might want to use the divide and conquer method, or just checking each displacement in your map).
Another strategy is to select all displacements at once (select the "displacements" visgroup (in the visgroup-window to the right in Hammer), then press "mark") in the ignore group mode (button "IG"), then use the texture browser to replace every instance of the nodraw texture to another one (with the "only in marked solids" button checked).

warning: cluster portals saw into cluster
(I think) VBSP has made a concave leaf(or in other ways invalid) that can see into itself. The solution is to simplify your leafs (func_detail) as much as possible to avoid this error, but usually (or sometimes) you will find no bad things come from it and your map runs as it should. If you got unexpected low FPS somewhere, this may be the cause. Finding it may be hard, and usually ends up in using cordon tools or just not doing it at all. First look at complicated parts of your map, try to use glview to find it. I've also heard about this being caused by overlapping brushes or brushes that are off-grid. Allthough i find this unlikely, I am not sure if it isn't, so keep those possibilities open too.

27 degenerate faces
You have ## face(s) with no surface. This happens when two of the three points making up a triangle are at the same place or all three are in the same line. (and thus don't make a legal, but a degenerate triangle)
I believe this is a displacement only error, so try to find your errors there, if you find any problems in your map because of it. Dont do it otherwise, because it could take very long to find the offending face.

zero area child patch
A solid in your level has a face with no area. My guess is that VRAD is trying to create a lightmap for a face that doesn't exist. Maybe you have an invalid brush? First check hammers problemchecker (alt+p in hammer). If that doesn't help, find the brushes using the cordon tool or visgroups. Or, do what www.snarkpit.net suggested, find the offending face with a text-editor... "

Also, check your lightmaps in hammer. I'm guessing its because of the degenerate textures and the portal errors but you never know.
