Exporting models from Crocotile3D to Unreal Engine 4 (.obj). Texures are always blurry. I want crisp, clean textures

Can anyone help me? I am exporting models with textures (.obj) from Crocotile3D to Unreal Engine 4. I want them to be crisp and clear, as in the left image (Crocotile editor), but only get blurry, as in the right image (Unreal editor). Whether I export the model at scale x 1 or greater doesn’t make any difference. My textures are 16×16 pixels.

I have watched endless videos and tinkered with settings but been stuck for two days. Any help or advice will be much appreciated!

Crocotile3D,, Unreal Editor, Crocotile Eport Settings
