I'm sorry for the lackluster description...

It starts Gm7b5 - C7 - Fm with the melody Bb G G Bb C Bb Ab F

Then Dm7b5 - G7 - C with the melody Ab G G F E

Then the B section is Cm - F7 - Bb, Ab7 - G7

I have a surface with sand and grass painted using mesh paint. The whole surface is a flat plane, and to achieve the desired resolution for the mesh painting I had to subdivide the plane to the point that it has over 100k triangles. This seems incredibly wasteful.

I tried to use nanite but it caused the mesh to reduce into more simple geometry, which totally messed up the grass and sand texture into an angular blotchy mess as there were a lot less vertices.

Is it possible to simplify the mesh without affecting the mesh paint? Can I somehow bake the texture onto the mesh and then reduce the number of vertices?

I've just finished my game after a year of development and I'm trying to clean things up. I've pinned down the source of lag to these trees I'm using.

When I get up close to the tree, FPS drops from ~60 to ~30. I got them off the marketplace, I'm not sure if they were optimised for games in the first place and I really don't know how to do that myself. They have pivotpainter files and a slight swaying animation, which I know nothing about. They're set to a fixed LOD with ~25k triangles. This one in particular has been scaled up quite large in the level.

Are there any red flags here that suggest why this is causing lag? Too many tris? Should I be using nanite?
