Specular File Size for HQ Textures?

I'm not sure ... but on this page
alf-si.tumblr.com/HQ_ts4_English

dice that are 1024x2048

and I think it's logical because having more details, more realism ... you need more performance ... then you need a bigger space, no?
I hope someone else will help you n-n

anyway you could try and download an HQ file and compare sizes

for example a serenity lipstick called kylie cosmetics has a specular size 1024x2048
and everything has specular, because as you know it is the brightness of the objects of Cas( clothes, lipsticks...)

and to render in the game you have to modify the graphic rules and in sims4studio for hq textures

tutorial: remussims.tumblr.com/private/152479184875/tumblr_oftujuQBaG1rr75da

tells you the specular size and the other things

note that in the graphics rules file configurations only multiples of 2 appear

why 1024 because you are multiplying it to 512 by two

and that's why 2048 because you are 1024x2

ok ... I do not know if you understood me
