Skyboxes | HL2 / EP1&2 / BETA

Prop Effects that can be used for scene building.

Contains 3 models, the HL2 skybox / the EP skybox / the Beta Skybox
Each contains their respective skyboxes (which are plenty).

Meant to be used for posters, not the average gameplay experience, if you want that, simply get the Skybox Editor Tool : https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2408809152
What this addon has over that is simply convenience for the people who scenebuild and render posters.

You can install the Effect Resizer addon to resize these should you need to (its also generally good to have anyway) :

You can install the Easy Bodygroup Tool addon for convenience (its also also generally good to have anyway) :

Otherwise, you may access bodygroups by pressing C, right clicking on the effect and clicking on the desired bodygroup.

Have fun!
