Texture image seems wired in material,

Hi!
I’m beginner of unity. I created some meshes in blender and imported them by fbx file. The texture of them is a 8*8 palette image.

But this image seems wired in material inspector.


So I got a bunch of meshes with wired color. Then I doubt it’s texture’s fault so I created a 256 * 256 pixels image by snapshot and used it as texture. Now everything is fine.
I wonder why does this happen cause the tutorial video I watched said that it is good for performance to use a low resolution texture. I may want to use it again if I can find a way to solve this issue.

I assume that you don’t want the texture to be blurry. In your Texture Import Settings, change the Filter Mode to Point and apply changes. If that doesn’t help, try changing the compression quality.
