fetch chop

[Dries]

Hiya,

I can't seem to get the fetch chop to import channels for the whole animation range. That seems odd.

The object chop can do it, but that has only a limited number of channels to import (transformation). I definitely like the select options of the fetch chop: all, created or non-constant, but importing say "bank" only gives a constant channel allthough it's animated at object level (of a camera).

yeah, have to answer my own question again: fetch chop does work for keyframed channels, but not for expressions; I had sin($F) in the bank parameter. That's a pity actually because I was looking for a universal way to export objects. Now I first have to check whether there is an expression and do those separately. Or has anybody a better idea?

Bit of a pain, but have you tried using the record chop after the fetch chop, that should let you grab the values for the whole animation.

Interesting, don't know what record does. I'll give it a try tomorrow. Thanks.

It's a funny little chop, gets you out of a spot sometimes. Don't know how well it will fit into a script. Basically you turn it on and play the animation through, any values that go into it get recorded and you end up with a graph that varies correctly over time.

When you type sin($F) in a parameter, it actually creates a key at frame 1.

The problem is that the Fetch CHOP only looks at that 1 key and so only brings in the data from it. You can workaround the problem by keying the last frame on your sin($F) channel.

On the 'Channel' page of the Fetch CHOP, there's a parm named 'Channel Range'. Set this to "Use Start/End", and enter the Start & End range of your animation (by default, in seconds; Common page - Units parm to change to frames). This will fetch that range instead of the one frame the expression happens to be at.

Wow, okay. It seems to be in the little thinks. Both edward's and malexander's technique work well, just the last one seems more universally applicable. Thanks. I'm glad I asked.

Should have thought of that, kinda assumed you'd tried all that and it wasn't working, should have tested it myself first. Record is still worth getting to know though
