Alright sometimes you get a message after being kicked off b.net that you need to fix nooks and crannies right? Well if you don't good for you , but if you do, people may tell you to make alot of walkable terrain or unwalkable terrain. This mostly happens with installation tileset and ice world tileset. I have an easier way where you can keep all your little spaces. Copy the entire map and paste it on a blank map of the same size, tileset, etc. It may be a pain in the ass to correctly center your map's terrain, but after maybe 20-40 (maybe longer if your an idior )minutes your done and no more problem, but make sure you finish the terrain first before you do this :\.
Idk if this will work for you but hell, it does for me.

I never had that problem before, but good job on fixing a bug created by blizzard.

ITs not as much as a bug as it is a block in the pathfinding AI, I belive.

It is not a bug, they thought that if the map terrain was way too complex it would slow down the path finding system so they added a limit. I don't know how SC calculates the number of nooks and crannies (I thought that it just counted the number of edge tiles in the terrain), and I don't know either how copying the terrain fixed it.

I think copying/pasting it fixes it because copying/pasting the terrain doesn't copy ALL of the tile data (not in SCMDraft, anyway).

For example, if you copy and past a section of isometric terrain, then try to place isometric terrain there "normally," it doesn't merge the terrain very well (okay, it doesn't merge the terrain at all).

Yeah I know that, but SC only reads the MTXM section (or that's what I thought). It might read the TILE or the ISOM sections only to check if the terrain complexity is too high, so if they're missing it will still load the map. Not sure though.

EDIT: Marine could you test if protecting the map with PROEdit or Uberation2 also fixes the problem? (remember to backup an unprotected copy of the map!).

If you made an exact copy, Im sure you didnt match each tile for tile, its was just the isom part. Thats probably why it worked.

This topic just made a new station map possible. Laura and myself thank you.

No, Make RE:RC2 nao! ;O

Laura does the station maps, i just delivered this information.

Anyway ive got quite a few projects im working on. Dont worry though DM, itll get done. And if it doesnt for whatever reason, ill release what i have done and you/darkling/someone respectable can finish it.

Meh, hope those go good then.

As far as I know this error is calculated from the ISOM section in the map data. The ISOM section is not copied over when you Copy+Paste terrain using an editor such as SCMDraft 2. The ISOM section is responsible for allowing the user editing the map to properly place isometrical terrain.

You mean a Fifth Station type map?

But deleting the ISOM section does not prevent SC from loading the map... interesting...

I have something else you might find interesting. Whenever you attempt to load a map to play in StarCraft, the game will check the integrity of all data sections in the map file. This includes ALL legitimate data sections, even those which are not actually used by the game, such as the ISOM section. Thus a person may remove the ISOM section entirely and the map is playable, but if one attempts to corrupt it with bad data the map is not playable.

I had this problem when trying to make my Star Wars RPG. I had to cut the terrain short because of that

No. I've tested it and corrupting the sections that SC doesn't read have no effect. The map is still playable. I'm still not sure if SC checks the ISOM section for the nooks and crannies problem. Could someone PM me a map which displays that error so I can check it out?
