Env cubemap: Difference between revisions

Revision as of 12:39, 7 May 2018

Template:Base point It specifies a location for which a cubemap will be generated when the buildcubemaps console command is executed.

Objects with $envmap-enabled materials will use the nearest cubemap as their reflection.

Note:Cubemaps will contain static props, sprites and decals, such as enemy blood and user sprays.

A cubemap example containing the white static prop car, a sprite and decals. Note that the blue physics prop car is not visible in the cubemap

Cubemap Size ([todo internal name (i)]) <choices>

The resolution of each face of the cubemap. Remember that the actual number of pixels stored will be your selection times six!

Comparison of reflection quality (1x1 is not included because it does not reflect at all):

Brush faces ([todo internal name (i)]) <sidelist>: An optional override for individual brush faces, forcing them to use this cubemap instead of one closest to them.
To select faces, press the "Pick" button then click on them in the 3D view. Hold Ctrl to toggle a face on or off.

Example of how the env_cubemap should look when placed in the correct height

Example of how the env_cubemap should be placed around doorways, or other exits such as windows or drops.

Place the env_cubemap in the center of the rooms you want it in (unless there is a reason not to, e.g if the cubemap will be placed inside a prop, or there is a better place to put it).
You may also add env_cubemap entities on both sides of the doorframes or other entry points with the same distance for smoother cubemap transitioning between rooms.
Go top map->Entity Report and mark all your env_cubemap entities.
When marked, right click one of the three 2d viewports and select "transform". In the new window select "move" and enter "64" in the Z line, leave X and Y by 0. This will move all env_cubemaps to the Source engine eye height.

The env_cubemap entity should always have the exact same distance from the ground as the info_player_start entities head.
