Don't know if anyone had posted this but to fix models in Lavender:
>flying above ground
Increase eye height in:
Steam\steamapps\common\Lavender\Lavender_Data\StreamingAssets\default.ini
You can find the amount needed by dragging yourself down with playspace mover, checking the offset, then adding that to the default height.
>view point too high or low
Fix the above first because it seems to affect this. Drag the view point significantly higher or lower in Unity and reupload. My view point is slightly above the eye brows to get it to line up with the pupils. It's the opposite in VRC and I have to put it in the mouth.
