Jason Posted October 27, 2004 Share Posted October 27, 2004 Hi all, It's been a small quite since I animated too much in Houdini using keyframes. Is it there a way (and I looked and couldn't find one) to set the behaviour of a keyframed channel beyond the extents? e.g. OutExtend = match(), InExtent = constant() or something. It seems like a good idea to have each channel know how to evalaute beyond its keyframes on either side. (No, not with CHOPs) Thanks all, Jason Quote Link to comment Share on other sites More sharing options...
michael Posted October 27, 2004 Share Posted October 27, 2004 hmmm..yeah... the problem is that there isn't a segment after the last keyframe...so how do you tell Houdini what to do... maybe an RFE would be to give keys themselves these functions...?

And you could set it in the UI or with hscript like: chextent /obj/geo t* -in constant() -out matchin() Quote Link to comment Share on other sites More sharing options...
michael Posted October 27, 2004 Share Posted October 27, 2004 yeah...that's good stuff right there... it might also be a cool idea to be able to have expressions on keys ... like a key at frame 100 value = $foo+1 Quote Link to comment Share on other sites More sharing options...
edward Posted October 28, 2004 Share Posted October 28, 2004 The control for outside the regular range is already done in the latest baseline. Mike, you can ask Neil to show it to you if you want to drop by before you leave. As for expressions on keys, you can do that in the channel editor S,V,A fields. I forget the exact syntax now but it would perform them on the selection right away. Again, I'd have to ask Neil. Quote Link to comment Share on other sites More sharing options...

edward Posted October 30, 2004 Share Posted October 30, 2004 Oh, I found out how to do the graph mode thing. Select your keys and then delete the --- in the input field, put in something like: +2 or *2 (to add 2 or multiply 2) Quote Link to comment Share on other sites More sharing options...
