could anybody tell me , how can I export houdini's animation ,such as character animation to maya? So I can use maya's fur and cloth to do the rest parts.

[tallkien]

build identical rigs in both packages with the same names (bones, effectors,etc), then use the tools in the codex section of this site(convchans, chandump)  to convert animation data. I've done this before so I know it works fine

A simpler method might be to export sequential polygon geometry file from Houdini using the Geometry ROP. After this you can import sequence in Maya as blendshapes. You need to do a little scripting to do it, but its possible and at least you're guraranteed to get exact lineup. Now you can run your Maya dynamics on top of this.

thank u. and how to export maya scene into houdini?!
for example, I created a scene in maya, and then I want to make particles in houdini...

hey ykcosmo

what i do is i wrote a little script that exports all my objects (polys) in maya to obj files and then use the file sop to bring them in

and iges for nurbs and also use a file sop to bring them in,
i would then run a merge between the two file sops.

just make sure that u use $F as ur extention on ur file in houdini, so that you actually import your animation from maya and not just one file.

as for camera move, theres a little conversion that takes place between maya's cameras and houdini's cameras,


then as for camera moves, just export ur camera translation data out as movs and bring it in through ur CHOPs, just make sure ur sample rate is that of ur scene file in maya, ie pal =25

and that should be that, i got a really good match going between packages,

i think you should check out

anyways

hope u come right

all the best

i hope i can upload there a script in the next three maybe four day's, when iam ready.

i write a script that imports obj sequences into maya.

this script control's the visibility of the objects frame by frame.

the only problem i got is, i write for every object a script operation.

and that is realy shit, i need to build it with if and else, but i got no knowledge of it.

so iam now at frame 100.

i think i script it till 200......i think its enough. and it works, with importet models.
next problem is, that i cant rename the importet poly model's because the script works with the names........

in need a idea and help to solve this two problems

[Overload]

That should also retain your UV data if you have any..

[Jason]

Don't forget about the OdWiki Translation Page - and feel free to add to it as you go.

[Mainframe123]

i have to say, i tested my script a month ago....with 10 frames of obj anim.
and all was right.

And now i completed the script up to 100 frames...........

and all is wrong.........???????????????

i think i made a big mistake.

[Mainframe123]

I got now a good script to import obj sequenzes into maya

its a script from tonytouch

global proc loadOBJsequence(string $directory)
{
int $startframe = 1;

string $file_list[] = `getFileList -folder ($directory + "/") -fs "*.obj"`;

for ($i=0;$i<`size $file_list`;$i++)
{
file -import -options "mo=0" ($directory + "/" + $file_list[$i]);
rename "polySurface1" ("importObjSequence_" + $i);
setKeyframe -at visibility -t ($startframe + $i) -v 1 ("importObjSequence_" + $i);
setKeyframe -at visibility -t ($startframe + $i -1) -v 0 ("importObjSequence_" + $i);
setKeyframe -at visibility -t ($startframe + $i +1) -v 0 ("importObjSequence_" + $i);
}

}


loadOBJsequence("c:/temp/OBJfolder");

Hi folks

I need to export camera animation data from Houdini to Maya. Actually I am doing it by exporting a .chan file from Houdini with animation data and wrote a mel script in maya to import the table and using it frame by frame.

Does anyone doing this in a more elegant/efficient way?

thx in advance

chris

Hey chris

actuallly i've just finished writing a script that does just that, please give it a try
im doing it to facilitate our pipe from houdini to massive and im stopping half way with maya, so i can go via maya into just about any package.

its written in python, in terms of how to use it, basically just save ur cam out from chops using ur fetch chop, make sure its a chan file and not bchan, and point the script onto that file.

then copy and paste the mel text that is returned... and paste that into maya :-)
please let me know if u run into any issues,

brian
