Full grown humanoid sims (teen - elders)
No transparent textures (glasses, alpha hairs, eyelashes, some nails) *
No skirts*
Use clothes/hairs with a lower poly count (if you can tell) *
Use short hairs (above the shoulder) *
Toggle off reshade/gshade
Note the savefile you place sim in
Keep animation in mind (depends on how much you mind clipping)
Do not use cc shoes*
For all bullets that have a * next to them, these are suggestions I would recommend if this is your first time making an animated deco sim as these make need additional steps to accommodate for or cause trouble down the line that would be difficult to solve if this is your first time. Again, these are not impossible to include in the future, these are just my recommendations for beginners.
