To slice a smoke animation sprite sheet so it plays smoothly without shifting, which option would you use?

• A. Automatic Slice
• B. Grid By Cell Count
• C. Grid By Pixel Size
• D. Slice by Name

Answer: (B)

Grid By Cell Count ensures each frame is a consistent rectangle by dividing the sheet into a fixed number of cells you specify. For a smoke animation, the frames are usually the same size and laid out in a tidy grid, so setting how many frames fit across and down lets Unity calculate a uniform cell size. That uniformity keeps every frame aligned on the grid, so when the animation advances from one frame to the next there’s no shift or jump—the sequence plays smoothly.

Automatic Slice can mis-detect borders if there are subtle gaps or anti-aliased edges, which can cause frames to crop or offset. Grid By Pixel Size (cell size) requires knowing the exact width and height of each frame; if the layout is defined by count, using pixel size is more error-prone. Slice by Name relies on naming rather than precise geometry, so it won’t guarantee consistent frame alignment for a smooth loop.
