Textures resolution and screen size

Hi,

I didn’t find any information about this, so I decided to ask my question here.
I use 4K resolution textures for my materials and I am interested about how it will be displayed on screen that have lower resolution then textures. Will it be downscaled? Is r.screenpercentage can do it? I mean, If the original texture res is 4K, then, what resolution will be on fullhd screen if I use r.screenpercentage = 100? If I am wrong, please write you answer how can I change resolutions of the textures on different screens.

Thank you

Hello,
When importing textures a chain of mip-maps are generated. Each mip level is half the resolution of the previous level.
A 4096x4096 texture will create mip-level1 4096x4096, mip-level2 2048x2048, mip-level3 1024x1024, mip-level4 512x512, mip-leve5 256x256, so on and so forth.
The texture editor has settings for this in the level of detail section (see docs link text)
This decides the default settings for displaying the texture.
A texture sample used in the material editor also has custom settings for mips (click on the sample node and check the details panel) . ( link text)
