Any [[GoldSrc]] mapper looking to start working with Source has given thought to porting over their existing work. Generally the easy way to do this is to load the .RMF into the new [[Hammer]] and update the textures and entities. If that isn't available, this tutorial shows how to port a map from a decompile.
 
==Tools==
 
Many tools exist for the purpose of decompilation and porting, but the ones we're looking at are called [[Half-Life Unified SDK|Half-Life Unified SDK Map Decomplier]] (decompile) and [[MapFool]] (update). Be sure all the [[WAD|WADs]] needed for the map are handy.
 
==Decompilation==
[[File:HLUnifiedSDKMapDecomplierScreenshot.png|thumb|350px|Screenshot of Half-Life Unified SDK Map Decomplier (in GUI mode)]]
Run {{code|HalfLife.UnifiedSdk.MapDecompiler.GUI.exe}} first configuring it whatever you want but here, we just gonna leaving it default. Then select the Output Directory, something like {{code|C:\Program Files\Steam\steamapps\common\half-life\valve\mapsrc}} for example (create one if it's doesn't exist). After that, go to File > Convert, select the .bsp file, then it will automatically converting it to .map.
{{Tip|You can hold SHIFT then drag to select multiple .bsp files.}}

None of the textures will exist in the map, so you'll have to use MapFool to update their location. Load your map into MapFool and load the WADs (from File > Options...) and .map into it. After loading all the WADs, point MapFool towards the location of your copy of [[Vtex (Source 1)|Vtex]] and where you want it to dump all your textures.
 
Using "Upgrade Obsolete Entities" from the Tools menu, change any obsolete or deprecated entities to their Source counterparts (<code>[[func_illusionary]]</code> turns into <code>[[func_brush]]</code> entities with the solidity turned off, for example).
 
==Porting textures==
 
Export all the textures in the WADs to TGA. Navigate to it and turn them into [[material|materials]] using Vtex. Some textures can't be converted right away because Source requires all textures to be in powers of two. Any irregularly sized textures will need to be resized in an image editor before recompilation. 
 
Assuming everything was put in its proper place, you should have an almost perfect replica of your favorite HL1 map.  Don't compile right off the bat, however. The way BSP2Map works is that, instead of creating one solid, it creates six very thin solids. This almost certainly will lead to broken solids and going way over [[VBSP|VBSP's]] compile limit.
 
{{Todo|Figure out how the HL Unified SDK Decomplier works, and does it's able to compile the map without modifying anything or reacting VBSP limit.}}
 
You'll have to fix all of this yourself, fortunately. Half-Life 2 BSPs solve the problem by saving the original solids in the map, so it's simply a matter of extracting them.
