5. NIMA Supported Assets Nima supports most popular image formats, image sequences, and PSD files (8-bit mode). Be sure to flatten any PSD layer effects before importing into Nima. PSD Imported PSDs appear as a single top-level asset (with a PSD icon), which can be expanded to reveal all the layers included in it. Image Sequences Import an image sequence into Nima by dragging and dropping multiple images that are named sequentially (e.g. image_000.png, image_0001.png, image_0002.png, etc). https:/ /www.2dimensions.com/learn/manual/assets
