Update: my method sort of worked, so what i did was use mantis lod editor on all the meshes saving mesh as is creating a 100% clone with bones and all, then replaced them on the prefab manually, then i exported that new setup to fbx with built in unity fbx exporter, I ran the old avatar in play mode with vrcfury i added fix write defaults disabled to the avatar to generate the menu's ect for play mode then i found them in the vrcfury tab and duplicated them and moved them to a different location, had to reapply bone positioning manually when setting the rig to humanoid when i did the new fbx set up, then i used the exported mesh to rebuild the avatar turning off what needed off, leaving on what needed to be on, shifting the old materials onto the new meshes, ect. i have a feeling the armature isnt going to be attached to the fbx so when i do get around to testing it if it fails i can use that exported fbx to fix that in blender but after that it should be all good menus appear to work fine in play mode and i have since removed gonso from my project so it isnt messing with my results on this test
