Cubemap Screenshot Tool

Ever wanted to make a 3D photo in Garry's Mod? Well, now You can!
This little utility Gmod Tool let's you create six photos at the time. You can later stitch those images onto a cube in a 3D software or using render[wiki.facepunch.com] library in Garry's Mod LUA.

Go to the Spawnmenu, in the Tools tab under the Render you should have a Cubemap Screenshot. Press Left mouse button while using that tool to take a Cubemap Screenshot from the current view point.
You can adjust the resolution using a slider.
To make the front-face of a cubemap point into the looking direction just check Relative to view checkbox.
The files are saved in "garrysmod/data/cubemaps/<map name>_<index number>" as six PNGs named "left", "front", "right", "back", "up", "down". The resolution of the image are limited by your display's lowest dimension (typically the height).

- Last cubemap preview option.
