Are group opacity and blend modes preserved when exchanging Aseprite files?
Resprite's current Aseprite conversion does not preserve group opacity and blend modes equivalently in both directions. Resprite can edit these properties internally, but that does not guarantee that they survive import or export.
Does Aseprite support these group properties?
Yes, through the experimental Compose groups separately option under Edit → Preferences → Experimental. Aseprite introduced it in v1.3.11-beta1; its official tests cover group opacity and group blending. See the release notes.
As checked on September 7, 2026, the option is still disabled by default in Aseprite v1.3.18.3. The Aseprite format can represent these properties, but retaining them still depends on the import and export workflow.
What happens in each direction?
- Importing into Resprite: Groups use full opacity and Normal blending. Ordinary image-layer opacity and supported blend modes are handled separately; this does not mean all layer opacity is discarded.
- Exporting to Aseprite: Group opacity and blend modes are not preserved as equivalent editable group behavior. Reopen the exported copy in Aseprite and compare the result.
Within Resprite, select the group and open its layer properties to adjust Opacity and Blend Mode. Those edits belong to the Resprite project; changing them does not remove the conversion limits above.
Keep an editable original
Keep the source Aseprite file and a .resprite working copy. Check the converted file before continuing, especially if several layers overlap or use different blend modes.
For one layered frame, PSD export can retain supported group properties already present in Resprite. It has its own limits and does not restore group settings lost during ASE import.
