Why do layer effects change when exchanging files with Aseprite?

Resprite can exchange supported artwork through .ase / .aseprite, but some properties do not round-trip equivalently. Keep the source file and a .resprite original, then check the converted copy.

When importing into Resprite​

Group opacity and blend modes are not imported equivalently: groups use full opacity and Normal blending. Aseprite tilemap layers are not imported as editable Resprite tilemap layers. Ordinary image-layer opacity is handled separately; the group limitation does not mean all layer opacity is discarded.

When exporting to Aseprite​

  • Group opacity and blend modes, and clipping masks: not preserved as equivalent editable features.
  • Layer styles, such as Stroke and Shadow: skipped, rather than automatically baked into the exported pixels.
  • Resprite tilemap layers: rendered as ordinary pixels; the tilemap structure and tileset resources are not retained.
  • Reference images: not included in the exported layered file.

These are limits of Resprite's current conversion workflow. They should not all be attributed to features missing from the Aseprite file format. See Aseprite file compatibility for details.

How can I keep the intended appearance?​

Work on a duplicate. If live layer styles need to appear in the exported artwork, rasterize those styles in the copy before exporting. Check group blending and clipping in the destination app; do not assume a different layered format will preserve every feature.

For one layered frame, PSD export offers another workflow with its own limits. To exchange editable maps, use Tiled formats.
