try to not have 30 mats
try to not use too mayn 4k textures if you can help it quality-wise; 8k please none
keep your dyn bone count low, parenting all bones to the same root can help cut down on script count
separate face mesh with blendshapes from the rest of the model if it's overall hipoly and delete the shapekey modifier from the remaining mesh
try not to have too many split meshes; 2 is good if you do the prior adjustment
atlasing can be good but can make it hard to use smaller textures per material depending onc larity of logos, text, etc.
use a shader with a small footprint or at least one with a lock-in system (most megashaders have this now)
crunch compression at 50% (default) quality helps for filesize; dont let retards suggest that it doesn't matter when unpacked because the actual visual quality does degrade
