alves_mauri Posted January 16, 2008 Share Posted January 16, 2008 Hi guys, I am trying export obj files (a basic bouncing ball animation with 10 frames as a example) from houdini to maya, but something very strange is happening, all obj file has the same data (same vertices, same faces, etc), I did not notice any diference between them, seems the houdini exported only the frame 1 of may animation. So, when I imported them in Maya, every file was loaded in origin, doesn Quote Link to comment Share on other sites More sharing options...
symek Posted January 16, 2008 Share Posted January 16, 2008 If you are animating a ball in OBJ level but exporting in SOP level, you won't have an animation at all. Is this your case? What you can do is: - use a Geometry ROP to export your ball with world transformation - or create a new object. Add Object Merge SOP and import your ball with it. Add "." (dot) in transformation object field (the very first field in SOP - I can't check now its name). Now you can export your ball with world level transformation. hope this help, sy.

SpencerL Posted January 16, 2008 Share Posted January 16, 2008 Also, keep in mind that Maya cannot read .obj sequences unless you do some mel scripting. Quote Link to comment Share on other sites More sharing options...
spev Posted January 16, 2008 Share Posted January 16, 2008 unfortunately in maya you have to write a mel script to read in the objs and then use blend shapes to animate between them....I believe that there is a script on highend3d called objMorphSequence.mel or something like that. I found the script...you can find it attached to this mail Best objMorphSequence.mel.gz objMorphSequence.mel.gz Quote Link to comment Share on other sites More sharing options...
MENOZ Posted April 7, 2008 Share Posted April 7, 2008 - use a Geometry ROP to export your ball with world transformation is there an option to export with world transformation? i didn't find it... Quote Link to comment Share on other sites More sharing options...
symek Posted April 7, 2008 Share Posted April 7, 2008 (edited) Sorry, I was wrong or something has changed recently (don't think though) .( Hmm, I think I checked it before posting..) Geometry ROP saves also SOP level Geo. Still you have a second method. Edited April 7, 2008 by SYmek Quote Link to comment Share on other sites More sharing options...
pclaes Posted April 7, 2008 Share Posted April 7, 2008 I am not sure if this is world transformation, but this works for me: create a new geometry at obj level, inside create an object merge, assign the correct object, but set the transform setting to: "Inside This Object".

Yes, this is world transform and the second option I mentioned.. I wonder how this would happen that Geometry ROP worked as I expected once...
