So I’ve spent the last couple of hours troubleshooting and pulling me hair out to no avail including searching through countless forums with no lucking of finding the answer. I’m planning a new ttt map which takes place in an opened up Ravenholm however I can’t actually get the map to open in the hammer.exe located in the Garrysmod bin folder. Basically I decompiled the first Ravenholm map from the Half-Life 2 Campaign (d1_town_01), went through and deleted most of what I didn’t need in the HL2 Hammer.exe, and re-saved the map as a new fresh .vmf. I even downloaded an old Ravenholm map someone made which basically cleaned it up and removed most of the entities and even then hammer wouldn’t open his map so I’m at a stalemate.
At this point I’m beginning to think it’s the textures since both the original vmf and the Ravenholm map I downloaded both use HL2 textures however most if not all of Half-Life 2’s textures appear in hammer under the “brush selection tool” so I’m not sure why it would be doing this. I also read several times that invalid symbols such as " and . may be causing the crash however this is a Valve designed map and I doubt there would be simple symbol errors however I’m open to that being the problem as well.
If anyone has any idea on how I can fix this or a new troubleshooting idea then please let me know since I do want to get started on this project as soon as possible. I’ll link the edited .vmf below in case people want to see for themselves what is causing the problem, for those of you who like to tackle problems hands on please feel free to download it and see for yourself what is causing it.
(I take no credit for the map or the .vmf I have decompiled thus far, obviously.)
