Hi~!
I’m 3d graphic designer for mobile games in Korea.
Our team make RPG game by using Unity engine.
So, I have some questions about texture format for good performance in the unity.
We use texture format TGA . It is not only my team’s, almost company use same format.
TGA has good quality but, it has heavy volume than other format like JPG,GIF,DDS…etc.
I know about unity format change system which make texture more less volume.
it makes rendering performance up, but total volume(download size in the online market)
is not changed.
So, I think to use more light-volume texture format (like dds,jpg), which is light in total volume and rendering performance both.
why do people use TGA usually?
what is the texture format UNITY’s best recommendation for mobile game?
The source format is mostly irrelevant, since Unity doesn’t use it for anything after it’s imported, and it has nothing whatsoever to do with performance in any way. The only thing that matters is the texture import settings in Unity. You should use whatever is most convenient (which is usually PSD since you can keep the layers and so on). Also avoid lossy formats such as JPG since they lose information.
