Texture dimensions

research on dimension sizes.
resolution can start from 1 x 1-8192 x 8192 which the pixel resolution that unreal can do. The pixels only go up in pairs. (2 x 2 ,4 x 4,64 x 64). The dimensions are measured in pixels

Today standard games are 512 x 512,1024 x 1024, and 2048 x 2048, this is a high resolution texture.

why do we use png


The advantages of PNG






"Higher compression rates PNG uses better image compression technology than GIF, which allows for smaller files that download more quickly


A Higher bit depths (more colors) PNG allows for 1, 2, 4, 8, 16, 24 and 32 bit images.


A permanent, royalty-free license PNG is being developed by the W3C, and will always be a free and open standard



Multiple layers of transparency PNG images allow for full alpha channel transparency, which makes moving images from one background to another easy





Built-in gamma correction Users can see an image the way it was intended to be seen by selecting the gamma level intended for their monitor"
