Rafal123 Posted February 27, 2006 Share Posted February 27, 2006 Hi people! I got .obj geometry which I import into H. This is a quite complex object but it's imported as a one, solid geometry. I wanna cut this one into pieces and split into different parts. How should I start with it? Quote Link to comment Share on other sites More sharing options...
GaijinYakuza Posted February 27, 2006 Share Posted February 27, 2006 Hello, You can try duplicating the object a number of times and then make groups for the differnt pieces that you want under each copy. Finally lock off the group node to reduce cook time. This is crude but it works. GY Quote Link to comment Share on other sites More sharing options...
Visual Cortex Lab Posted February 27, 2006 Share Posted February 27, 2006 a really nice method to select pieces when importing OBJ is the following (which takes some times.. but i found it the most effective) select a poligon from the "part" you want to isolate.. then switch as many times as you need to "point" <-> "primitive" selection mode ... at the end you'll have the part selected.. I know this sounds stupid.. but if the part is not exported as "cluster" (XSI) or comes with different material applied and you have a single primitive group.. that comes handy.. obviosuly you need such part to be actually "parted" out .. they have to be separated from the rest. hope this help somehow... this made me possibile to part out a human head model to delete unusefull parts like the eye "fur" (damn my engrish rocks).. the eyes..the tongue.. teeth.. and so on... by having just the face skin separated. after that I had groups for every part. cheers Quote Link to comment Share on other sites More sharing options...
michael Posted February 27, 2006 Share Posted February 27, 2006 I find two things help here the most 1) groups...if the modeling package exports them then you can use them in delete SOPs etc in Houdini 2) the selection option 'select connected primitives' will allow you to seperate out different chunks of geometry that are all part of the same obj...

sibarrick Posted February 27, 2006 Share Posted February 27, 2006 If the obj comes in with colors on it - which objs support - you can use the partition sop to create groups from the colors. Quote Link to comment Share on other sites More sharing options...
