UPDATE! Found a REALLY good tool (WAAAY better than Meshia) to reduce triangles! At like ~70% ratio it looks very close to the original:
Download this (Mantis LOD Editor Professional Edition), import into your project, then download this free non-destructive tool that uses it - Booth Link and import it afterwards
In Unity, add "NDMF Mantis LOD Editor" component to each object in your hierarchy that you want to edit.
Then press "Preview" and move the "Quality" button until you're satisfied with the ration of Quality/Optimization, also feel free to play around with other settings

This saved one of my avis I thought to be unsaveable in terms of triangle count: [image: aca2dab7-3f95-4e1b-9d6a-a537db23d8ed-image.jpeg]
