If I have PCache on, and I go to save a PRT file, it won’t use the cache, instead it’s greyed out and it re-processes the pointset. Is there a technical reason for that? If not, I’d really like it if I could “dump” a WYSIWYG PCache -> PRT without having to re-read and re-process the points.
The main reason for this is that the cache only has channels needed for the rendering, and all the materials and transformations have been applied. In general, the saved particles may request larger data sizes and more channels, and in both cases the cache doesn’t have the requested information.
A separate option to directly save what’s in the PCache makes sense to me, though. Probably in the right-click menu of the cache.

Ah ok. In my case I would have needed that extra channel stuff, so thanks for the explanation.
