I'm trying to get thumbnails to appear for a custom image format in Nautilus on 19.04. The problem I'm running into is the thumbnails will only be generated once I open the files (.VTF "
image/x-vtf" Valve Texture Format in my case) in GIMP which defeats the need/purpose of thumbnails in the first place.
I feel like I must be missing something. I added the MIME type and updated the thumbnailer with the proper .so file (
libpixbufloader-vtf.so) but still cannot seem to figure out why thumbnails aren't being generated before loading the file in an editor.
Does anyone know why this might be or some steps I can try to resolve this?
