SItoA translates ICE particle shapes to native Arnold shapes. The supported particle shapes are already documented here, but here’s a little more information about how they are translated.
| ICE Shape | Arnold Shape |
|---|---|
| Point | points (mode “disk”) |
| Disc | disk |
| Rectangle | box (with 0 height) |
| Box | box |
| Sphere | points (mode “sphere”) |
| Cylinder | cylinder |
| Cone | cone |
| Instance Shape | ginstance |
The Segment, Capsule, and Blob shapes are not supported. SItoA skips them and they are not translated into the Arnold scene source.
