Cache retime
Posted: 13 Apr 2012, 20:56
here is a compound that could be useful. It may not work for you but it is has so far got me out of a difficult corner. A very simple retime cache node, as we know that the substeps implementation does not always work with all compounds as its based on the simulation using velocity and not point positions and sometimes the director says 'exactly that but 1.5 times slower' and having to go through someone else's complicated ICE tree that has already had umpteen revisions, simply adding substeps is not always the easiest solution right now - if it works at all. But if you have already cached and all you want to do is slow down or speed up the existing cache point positions with a linear interpolate between the frames then this compound might be just for you.
Firstly its annoying that I can't have an external file read node, if so I could make this compound a lot easier to setup. so for this compound to work you have to manually go inside and edit the two cache on file nodes to point to your cache location. Or set up a cache on file node already and copy and paste the path into these two nodes. Once thats done you are good to go. It is still very limited and for now it only interpolates between point positions. This is only version 1.2 it has speed up / slow down amount with a toggle between the two and these values can be key-framed or have fcurves plugged in and if anyone wants to enhance it with rotations and colour etc then be my guest
