Hey Pierre, about instances losing shape animation on cache playback. 2 things there, an attribute called shapeinstancetime or similar is not being stored or read correctly. Here is a quick fix suggestion, take whatever logic is applied to the uncached instances in the sim and apply it to the cache. You don't have to apply caches with the cache manager you can read them in ice with cache on file node then apply additional logic like controlling shape instance time per particle On 21 Apr 2015 01:10, "Pierre Schiller" <[email protected]> wrote:
