Importing Cubemap Texture (help)

[SolemnXII]

When attempting to import a custom cubemap texture I can’t seem to figure out the proper command line arguments in order to do so (if possible with the current Texture Compiler). From the info Rorschachrev has gathered, the texture seems to need references to the separate parts of the image to be compiled as one.

The full strings of TextureCompiler (very useful!!):

Out of memory   Unsupported format  Error in format File could not be opened    File access error   Unknown error   -stat   File Name   Width   Height  Num Frames  Format  Bits Per Pixel  -nopoweroftwo   -nomipmaps  -normalmap  -cubemap    -format dsdt    dxt1    dxt3    dxt5    -fps    Frame-rate should be between 1 and 100.

An example of a cubemap texture used in game is:
C:\Program Files (x86)\Steam\SteamApps\common\Grim Dawn\resources\level art\water\environmentmap_skybrightclouds512_01

If loaded in the Texture Viewer you will notice the texture.tex is labeled (cubemap) and will have sub images in the drop down list for each side of a “cube”.

Any additional information would be appreciated.
