This is a complete pack with a lot of northern animals for decoration etc.
To pointing me in the right direction with sling loading, I thank @Grajo very much with his MOD: https://www.digitalcombatsimulator.com/en/files/3310436/
Some of the animals have been already in a Mod-Pack earlier on, which is no longer working in 2.5. I brought them up to the new standard and modified them.
Some of the animals were coming from Sketchfab and the user Pablo444 under CC Attribution.
I modified them with Blender 2.91 (Poligon reduction and DCS Structuring) and exported them to EDM Format.
My next plans are to create animated animals. However I have first to learn the DCS structures for exporting "bone deforming" EDMs.
Have a lot of fun.
