Map with no entities leaks

[Springheel]

Trying to track down a sound leak, I copied brushes from an existing map, moved them to a new one and surrounded them with a big cube. There are NO entities in the map at all. But when I try to dmap it, it leaks, yet a "cannot load map.lin" error happens when I try to load a pointfile for it. I didn't think maps COULD leak when there were no entities. Anyone have an idea what might cause that?

What does the leak error say?

[Bikerdude]

It might be a texture with an incomplete material definition, if the leak path goes through a solid brush and there isn't an entity origin in the void this might be the culprit.

 

The way I would check this is check the above texture in the .mtr and if it isnt that then try to the following.

1. hide all enitities, clip and patches, then
   
2. depending on how many layers you have export each layer as a prefab
   
3. open up a new map and import all the above prefabs but make sure to use main menu> file> import prefab so that the prefaab is inported in the exactly the same place as the map it was exported from.
   
4. change the texture on all the VPs to some solid texture - I use carpet texture because if you forget its easy to see.
   
5. open up one side of the map that opposite to where the leak is coming from to the void.
   
6. dmap untill you find the leak.
   
7. export all layers as prefabs.
   
8. open up the original map, delete all brushes, import layer prefabs.
   
9. yer done.
   

Now if the fix was simple you can ignore all the layer-prefab bollox.

Hmm, it says there is an entity, but nothing shows up in the DR entity list.

[PranQster]

Can you filter all but worldspawn, zoom out, and manually select everything left? Maybe you can find/delete it then. Perhaps it's something like a spline origin...but with nothing in the entity list...? That's strange

I had a similar-yet-opposite problem with the horse AI a while back. The model would not show in DR at all, but I could select its origin from the entity list. Also if I selected everything in the general area with the mouse, then the horse origin would become selected though the horse was not visible.

I just reproduced your result. I tried to dmap a completely empty map and TDM crashes. Add a caulk cube and turn it into a room, and I get your result: 6 brushes, 24 planes, 1 entity, everything else 0. That leaked and there was no .lin file generated. I suspect the 1 entity is $world itself.

 

I added a moss arrow to the scene and it dmaps fine. Maybe you do need at least 1 entity aside from world for dmap to work.

 

EDIT: The successful dmap with caulk cube + moss arrow showed 2 entities.

dmap prolly assumes at least one entity besides $world as it looks for a path from that entity to the void, and doesnt fail gracefully.

[RJFerret]

A map of just worldspawn has one entity...

// entity 0

{

"classname" "worldspawn"

...

 

But that's an aside, I'd need to see the map file to be of any help.

[Springheel]

I added a light and a speaker, and presto, it dmapped fine. What an odd result.

[stumpy]

it should complain that there's no info_player_start entity, maybe someone removed the check for player start entity and it produces a leak error instead.

[RJFerret]

I believe it won't complain about no player start unless you try to map it after dmapping it.
