Minimum diffuse texture size?

[AmiPolizeiFunk 446]

Hi Simmies, 

 

I've found that tiny diffuse textures bug out the editor. I have a prop where I really only need 3 pixels (white, shiny black and matte black) of texture map info. I made a 8x8 .png diffuse texture, and although it worked perfectly in blender, it bugged out once the asset editor got a hold of it:

Vaguely remembering that I've had this problem before, I simply upped the size of my .png's to 32x32 and voila, it worked perfectly.

Why do tiny textures bug out and what is the minimum diffuse texture size in pixels?

I would never recommend such insanely small sizes because of mipmapping, bad anistropy, bleeding in general.

DXT compresses textures in 4x4 pixel blocks apparently, so that would explain 3x3 not working, but I'm not sure why 8x8 didn't work.

I've tried a 16x16 for a logo prop a while back and it didn't look too good, so now I just use 32 as a min

At the end of the day the practical difference between 2x2 and 32x32 pixels is minimal in terms of resources used by the computer I think
