How to export RMFs [in Jackhammer] - A Tutorial for Counter-Strike 1.6

How to properly convert Jackhammer maps into RMF

I've always hated that problem when Jackhammer would export the RMF incorrectly. This mostly applies for porting to VHE, and maybe other things?

Here's your common problem:

  1. You make a map
  2. You save it as an RMF
  3. You try to open it in Sledge
  4. And then goes an error: " DOCINFO got "" "
Well, apparently that is caused by this: Jackhammer doesn't set a value for the DOCINFO parameter, nor it puts the DOCINFO itself into the RMF.

There are 2 ways to fix this error, but I'm having problems with the other one, so we'll try this:

Jackhammer < Sledge Editor < Valve Hammer Editor


The name of this method insists that the file is exported within Jackhammer, and then opened in Sledge Editor, and therefore exported again, to VHE.
And, of course, you'll need these: Jackhammer and Sledge Editor, and you need VHE to open the final RMFs, even if Sledge and Jackhammer can do that.

It's relatively simple, and I will show you how to do it, step by step:

  • Open your map in Jackhammer
  • Export it as a .map file (sometimes it is exported as a .max file)

  • Open the .map file in Sledge (it can open .max files too)
  • Check for any errors
  • (If you encounter them), try to solve the errors
  • Save the map as an RMF

  • Open the RMF in Hammer

WARNING: If you have off-grid brushes, you might get something wrong. Either way, both Jack and Sledge can handle off-grid vertices.

As for Method #2, I haven't found anything related to it. It's basically opening Jack's faulty RMF with a hex editor, and manually adding the DOCINFO at the bottom.

It's as simple as that. Happy mapping!
