Doesn't show texture size in Unity 2022. Не показывает размер текстур в Unity 2022

Give feedback if you saw my message!
Most likely, it's in the format that unity chooses by default. That is, if you change it to RGB32, then everything is displayed as it should, and this format does not seem to be supported.

Дайте обратную связь если увидели моё сообщение!
Скорее всего дело в формате, который юнити выбирает по умолчанию. То есть если поменять на RGB32 то всё отображается как надо, а данный формат похоже не поддерживается.

Hi, this seems interesting, however could you try to clarify/synthesize your different posts ?

[AndreyAs44]

Hi, I don't remember very well anymore, the problem was calculating the size of textures. In this case, the build was for android, ASTC texture formats (automatic most optimal choice of unity). For them, I manually added the counting function (in the existing code) based on my observations and approximate understanding of the documentation. The weight of the sprites practically reflected reality, although there were small discrepancies.
