Here is an assortment of tools I use for mapping and other HL related stuff. Some of these are repeats from other threads but in case the links go down or if my versions are newer, I have hosted these on one of my own servers so they will always be available.nnBSP Viewer is as the name says. It lets you open a map and move around in it. nBSP Viewer 1.56nnHL Model Viewer lets you open and view models along with making some changes such as the texture and size.nHL Model Viewer 1.25nnRESGen creates resource files that list files that need to be precached for a particular map on your server. nRESGen 2.0.2nnRevolver allows you to quickly make complex shapes for your maps instead of having to create them by hand with vertex manipulation.nRevolver b1nnSprite Viewer allows you to view sprites.nSprite Viewer 1.04nnSprite Wizard allows you to create your own sprites.nSprite Wizard 1.1nnWally is used to create your own wad files and custom sprays.nWally 1.55nnWin BSPC is mainly a bsp converter/decompiler. While not perfect, it was the only one I found that gave acceptable results. It also works with pak, sin and map files.nWin BSPC 1.4nnZoner's Half-Life Tools are a must when creating your own maps. The stock compilers are very restricted so use these instead.nZoner's HL Tools 3.4 Final x86 version (32-bit CPU)nZoner's HL Tools 3.4 Final x64 version (64-bit CPU OS must be 64bit as well!)

Sorry for the dead links, they have now been fixed! XD
