Porting Goldsrc maps to Source

This guide is a work in progress. If you have questions or problems ask for help in the Momentum Mod Discord. #

Before you start, you should know that maps with simple geometry work best for porting. Complex geometry can cause invalid solids which will need to be manually remade, and some textures will need to be realigned.

Prerequisites:

• Have a basic understanding of Goldsrc, Valve Hammer Editor, and potentially Trenchbroom

Download the .BSP and (in some cases) the .WAD #

Most Team Fortress Classic skill maps can be found on the TFC Refugees forum here: https://www.tfcrefugees.com/resources/categories/conc.4/
Maps downloaded from this forum always include any relevant custom content not packed into the map itself. Additionally many maps have descriptions and author info text documents included.
Of the files downloaded, the BSP is the actual map file, and the WAD contains the textures used in the map. In most cases custom textures will be embedded into the BSP itself.

Porting Quake 3 maps to Source

Before you start, you should know that maps with simple geometry work best for porting. Complex geometry can cause invalid solids as vertices tend to shift around if they are off grid, and you will be forced to recreate a lot of the brushes manually. Patches and props cannot be ported across either, so choose maps without those or you will have to spend a lot of time manually replacing them in Hammer.
