This is my testing, I use G3 Elastic Folks_Female_01_F.ctTBactor to Composer and launch to external PSD Editor (Affinity Photo).
But I do not get the message about "failed to transfer the file from another application". Which situation could happen?
I editing sprite and exporting the PSD file to the local address (Desktop).
After exporting, Using the PSD update function to reload character. It looks worked.
