I did see your mod on the nexus. when reading the commit section the people said it was broken. I will give creidit to you for the idea but all the work on this mod was done by me. with the use of openiv for RDR2 and serching for the right meta file.
I edited the ambientpedmodelsets myself. say that there was a better animals on the nexus but everyone was saying it was broken. i tried my best to make sure it's work.
