Visual Cortex Lab Posted December 1, 2005 Share Posted December 1, 2005 hm ... i'm trying to get more into CHOP .. since I need to better handle animation as well in houdini... but I'm already having my first hard step in it. Fetch CHOP op .. can I fetch a /obj/model/xform1/rz curve with it?... apparerntly nope. it seems like i can only fetch /obj/model/rz .. which is quite odd to me. any advice is really appreciated. cheers.

sho Posted December 1, 2005 Share Posted December 1, 2005 FetchCHOP is working fine here with 8.0.394. Is your animation done by expression or key-frame? If it's only expression, you may need to use "Use Start/End" as Channel Range in Channel tab. Cheers, Sho Quote Link to comment Share on other sites More sharing options...

Visual Cortex Lab Posted December 2, 2005 Author Share Posted December 2, 2005 I just post in this thread since is.. sort of related.. i'm stuck again.. this time doing the opposite. simple scene grid.. box.. copy sop which copy the box on the grid's points stamping a variable "posiy" which have the following value chf("/ch/ch1/math2", ($F+$PT)) nothing happens. no errors tought. ok.. even simpler example i'm stuck with: box... xform sop ... ty with the following expression: chf("/ch/ch1/math2", $F) nothing happens, no errors tought. WHERE am I wrong?... cant i "fetch" (or just scope in this case) a channel, whatever it is (this is generated from a wave and a noise, simple), from any OP using "chf" function? any help is really appreciated. cheers Quote Link to comment Share on other sites More sharing options...

Visual Cortex Lab Posted December 2, 2005 Author Share Posted December 2, 2005 try the chop() or chopf() expressions.. 22984[/snapback] ok worked .... thanks a lot (btw.. using chopf i was firstly missing the channel name as last part of the path .. and now i'll check if chf also needs that.. maybe that was the problem).
