wiiu_textures files

[madgaz]

Hi,

So I've extracted folders and files from the Lego Dimensions game to try and recreate some of the models in real life.
Some of the models show up in Blender without the textures/detailing.

When looking at the extracted files, there are the .txt files which I have been able to open without issue by converting to .dds.
However there are files with a .wiiu_textures file extension which I suspect is for the models textures.

I tried converting these to .dds but that hasn't worked.

Has anyone any experience of opening these, or know how to open them to see what is actually contained here?

Thanks
Gaz
