Xash3D is a custom Gold Source build from a scratch. Xash3D overcomes obsolete Gold Source engine's limits and provides for you a new quality of gaming experience and modmaking capabilities, for example: higher limits for bsp-models, studiomodels scaling, realistic values of lighting on server side, entity patch technology support, support of additional map types, support of precaching "on the fly", support for using real HD-textures (up to 4096 x 4096 px) for maps, models, sprites and decals in any played mod and many other features...
So it's very new build of Xash3D Engine. This pre-release version brings many changes, so if you interested in development of the engine, please try it now and comment what do you think, because there are more things to do before final release, and you have some time to test everything and help to make Xash3D better.
As always, there are compiled binaries for Windows, full source code for the engine and tools, the list of changes and (a bit outdated) documentation about the engine, plus game dll-files with some additional improvements which should go into 'valve' folder to replace old ones.
This build provides many innovations, improvements and bug fixes. Due to numerous and significant changes, it still may contain some minor bugs and incompatibilities with some of previously tested Half-Life mods, so Unkle Mike decided to share this version on public to make sure, that final release will be rid of most of potential issues.
There are some of most noticeable changes:
Due to some of compatibility reasons Unkle Mike decided to remove the support of HD textures ('materials') from the engine. If you have some suggestions about that, please comment too.
If you have any troubles with using of Xash3D, please check this manual: Moddb.com
Pay attention, that Xash3D-based mods (such as XashXT, Paranoia 2: Savior, Quake Remake) are not compatible with build 3887 yet, because their game code is closely associated with old features of Xash3D Engine. So please wait until they are properly updated too.
