Due to software limitations on the current version of Unity's PS4 builds, we can't use Substances in place of materials, nor can we reference the Substance's generated textures using a Standard material,
The last resort for us is to use the Export Bitmap feature that all the Substances have, however the alpha channels for the metallic or specular maps are not included with the export. They are all solid white in Photoshop, and Unity does not recognize the exported textures as having an alpha channel.
Is this a known bug or am I doing something wrong? I have the format for each Substance set to "Compressed" I also tried the "RAW" format with the same results.
Also for the Metallic texture channel, I have Smoothness (A) selected.
Any help would be great, thanks!
