Create Flipbook from Sprites loss pixels

Hi,
I’m currently experiencing a problem of creating flipbook from sprites. When I create generated sprites from textures and then turned the sprites into the flipbook, the animation loss some pixels. I set up texture as ‘NoMipMap’ and ‘UI’. Is there any step i missed to create a good looking flipbook? Thanks in advance.

It is actually a feature that (back to the material itself), but looks like a bug at first glance :slight_smile:
