Editing func detail

{{DISPLAYTITLE:func_detail}}
[https://ericwa.github.io/ericw-tools/ Ericw-tools] [[qbsp]] supports detail brushes which are similar in concept to Quake 2’s detail brushes. 

They don’t seal the map. To be compatible with existing Quake 1 mapping editors, detail brushes can be added by creating an entity with classname {{code|func_detail}}. When [[qbsp]] reads the map file, it will add any brushes included in a func_detail entity into the [[worldspawn]] as details and remove the func_detail entity. Any number of func_detail entities can be used (useful for grouping) and all included brushes will be added to the worldspawn.

This classname used on brushes textured with [[Textures#fence_textures|alphatested textures]] will alpha-mask the #255 colored parts of that texture rendering those parts invisible.

'''<span id="func_detail_wall"></span>{{code|func_detail_wall}}''' :
This func_detail variant doesn’t split world faces. Useful for when you want a decoration touching a floor or wall to not split the floor/wall faces (you’ll get some overdraw instead.) If it completely covers up a world face, that face will get clipped away, so it’s not suitable for fence textures; see func_detail_fence instead.

'''<span id="func_detail_fence"></span>{{code|func_detail_fence}}''' :
Similar to func_detail_wall, but never clips away . It is suitable for fence textures, never clips away world faces. Useful for dense fences, grates, etc., that are solid and block gunfire.

'''<span id="func_detail_illusionary"></span>{{code|func_detail_illusionary}}''' :
Similar to func_detail_fence, but with no collision (players / monsters / gunfire), and doesn’t cast shadows unless enabled with {{code|"_shadow" "1"}}. Useful for creating hanging vines or spiderwebs.<br>Combine with a clip brush for fences that can be shot through with hitscan weapons, but blocks movement and projectiles; suitable for fences and 2D railings.


Regular {{code|func_detail}} is analogous with detail brushes in Quake II, whereas {{code|func_detail_wall}} is analogous with the [https://developer.valvesoftware.com/wiki/Func_detail func_detail in Source 1].
