Cache on enveloped objects!?

[hidalgo]

Same old question, how do you apply a point cache file into an enveloped object in local space instead of global? after applying the cache to my object the mesh jumps back to his original position leaving the envelope....and me totally amazed.

thanks for the help

You shouldn't apply a cache to an envelope mesh. That's the whole point of caching, to remove the need for processing things like envelopes. You should apply the cache on the static geometry.

well thats not totally true, in xsi you know better then me that for example you need to point cache facerobot in order to use it on an enveloped character, i am not using facerobot, but i have anyway a character with a facial animation done separately from the body, therefore i need to have an envelope and the the point cache.

its amazing that with KP point Cache, a 10 years old plugin for xsi i can do it and i can't with the built in cache reader, there should be a way to do it fast.

I see. Where does your cache operator live in the operator stack? I believe it should be below the envelope.

[hidalgo]

well, thing is that i can't see any operator below or over the stack, with the exception of the mixeroperator (which should be the one) but putting it below the envelope seems to not affect it anyhow..

If its an ICE Cache try using the cache on file node to read and put the ICE operator just under the envelope operator. There may be more stuff going on with the mixer...

actually i tried that too, but the enveloped mesh get somehow distorted as soon as i apply the .pc2 file, kind of weird..by now only kP works, but its really old and doesnt have any chance of visualizing the clip...

The icecache files don't read in locally afaik. Big bugbear of mine! You could apply the icecache to a separate head and read that head as a shape onto your enveloped mesh? Before now I've resorted to adding a lattice deformer over the top of a cached walk cycle in order to get it to move along a path.

that sound a bit tricky

at the moment Kp makes the job done, but as i said i am sure there is a "newer" and fresher approach to that!!
