I only have substance painter, not designer but the process should be the same:
If your material/texture was created in a pbr metallic workflow, which is default in substance painter:
*export your document textures or one of the metallic pbr presets as png files. For gameguru don't use the unity pbr presets as unity combines metal and roughness in a single file.
*rename the files:
* texturename_color
*texturename_metalness
*texturename_gloss (rename the roughness texture output to that)
*texturename_normal (depending on your preset, you might get two normal files. One called normal, one called normaldirectx. You want the directx version)
*texturename_ao
You can also convert the files to dds if you prefer.
GG does not have plugins (at the moment anyway) to import substance files directly.
Also when you import the model in gameguru select that shader 'pbr_basic' if GG does not do so automatically.'
