Error: "Substance 3D in Blender: failed to load the Substance file"

Hi @Chek35964819j6ap , there is an issue where the .sbsar can't be loaded if the file path contains non-english characters or special characters with umlauts. In this case, the Cyrillic characters in the file path trigger the error. This is something we're looking into. As a workaround, could you try moving your .sbsar folder to one that does not contain these characters?
