hatrick Posted April 23, 2010 Share Posted April 23, 2010 hi, what is the best way to transfer uv's from an object (build in houdini export to another app) to original object in houdini... the imported object show the uv(vertex) atribute and everything is displayed correctly in uv view.... when i try to transfer the attrib into the tree houdini crashes? i use attribute copy sop... thx Quote Link to comment Share on other sites More sharing options...
old school Posted April 26, 2010 Share Posted April 26, 2010 A crash like this is most likely a bug. Have a look at the Side Effects Technical Discussion forum post on how to submit a bug: http://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=5972 Please post the bug there and it would be fantastic if you could post a file.

hatrick Posted April 26, 2010 Author Share Posted April 26, 2010 i ll post the file but one further question .... the reason why im asking is because i'm not shure about the z brush - houdini workflow ( i know there are some threads) ... in my case the the geometry is animated preceduraly !before! the mesh for z brush is created: something like: box - mountain - facet - primitive - fuse - extrude - bevel - subd - !!then export!! a.s.o. that is the reason why i can't use the zbrushgeo in my tree ... i only need the uv setup created in z bsrush ?? i m shure thats a pretty standard issue? thx a lot Quote Link to comment Share on other sites More sharing options...

anim Posted April 26, 2010 Share Posted April 26, 2010 your geometries differ in point count, or for your needs in vertex count attribute copy copies specified attribute based on vertex/point/primitive number, so it may produce unexpected results if they differ or are shuffled it should not crash however and it does not crash on my laptop, it works ok, except for the fact i described above if you want to copy attributes between geometries of different resolution use attribute transfer SOP instead, but you should align the geometries as closely as possible in 3d view before it should not be your case however if you just export model, make uvs in another app, then bring back, the point count should not change and using attribute copy is perfectly normal workflow then Quote Link to comment Share on other sites More sharing options...
