+### HD (external) textures support
+
+Xash3D supports loading texture replacements in TGA format for almost all types of models in the game, except alias models at this time.
+
+Textures are expected to be located at:
+* `modfolder/materials/<mapname>` - for a specific map
+* `modfolder/materials/common` - common for all maps
+* `modfolder/materials/decals` - for decals
+* `modfolder/materials/models/<model>` - for models (texture name must match the internal texture name in the model)
+
+Support for high-resolution textures is enabled setting `host_allow_materials` cvar to `1` or in the menu, in "Video options" section.
+
+#### Xash3D FWGS additions
+
+In addition to paths above, Xash3D FWGS checks following paths:
+
+* `modfolder/materials/sprites/<sprite>` - for sprites, except HUD sprites
+
+Also, to check which texture replacements are loaded successfully, failed or weren't found, a mod developer can set `host_allow_materials` cvar value to `2`. The engine will spew log at any developer level in the following format:
+
+```
+Looking for <replacement> replacement... <status code> (<path relative to mod directory>)
+```
+
+Status codes:
+* `OK` - texture replacement file was found and loaded into GPU memory successfully
+* `FAIL` - texture file was found but hasn't been parsed or loaded successfully. Refer to engine log for more details.
+* `MISS` - texture file wasn't found
+
+Example:
+```
+Looking for maps/bounce.bsp:!waterblue tex replacement...OK (materials/common/!waterblue.tga)
+Looking for maps/bounce.bsp:!waterblue_luma tex replacement...MISS (not found)
+Looking for {shot2 decal replacement...MISS (materials/decals/{shot2.tga)
+Looking for {shot4 decal replacement...MISS (materials/decals/{shot4.tga)
+Looking for {shot3 decal replacement...MISS (materials/decals/{shot3.tga)
+Looking for models/gman tex replacement...FAIL (materials/models/gman/GMan_Case1.tga)
+Looking for models/gman tex replacement...FAIL (materials/models/gman/inside_1.tga)
