old school Posted February 28, 2013 Share Posted February 28, 2013 The attribute has to be a primitive attribute of type "string". Your "test" attribute is an integer. The hint is in the parm roll-over help for the Attribute parameter on the Alembic ROP. All you need to do is add an Attribute Create SOP, create your named attribute (say "piece") based on $TEST and make sure that it is a string type. Then in the ROP Output driver, specify your attribute (in this case "piece" as the string primitive attribute) and you will create your pieces. 1 Quote Link to comment Share on other sites More sharing options...
WangHuan Posted March 1, 2013 Author Share Posted March 1, 2013 (edited) Many thanks to you ,Master Old School. I think you are right,but when I do like this ,I got the "Houdini Console". What's the reason? Edited March 1, 2013 by WangHuan Quote Link to comment Share on other sites More sharing options...
WangHuan Posted March 2, 2013 Author Share Posted March 2, 2013 Oh,This is my fault.I type the wrong format(now,I know the right format should be "@name==*" , forgive my stupidity.) in the Partition Attribute,so It give me a"Houdini Console". Follow the Old School 's method,It is working!thanks to you,Master Old School. But,I encountered a new problem that if I use two (or more) PRIMITIVE geometry(Primitive Type:Primitive)merge together.and then add a connectivity SOP and a Attribute Create SOP,type the attribute in the Alembic Partition Attribute,I can get the right pieces objects.But if I use two(or more)POLYGON geometry(Primitive Type:Polygon)merge together,and then ... ... ,it doesn't work. In the convert SOP ,it haven't a function to convert a polygon to a primitive.and I don't know how to add a "polygon attribute" like a primitive attribute. If you can't understand my bad English.Please download my file.I think it will help you understand my problem. exportGEO_problem.hip ABC.zip Quote Link to comment Share on other sites More sharing options...
WangHuan Posted March 2, 2013 Author Share Posted March 2, 2013 P.S. MY QUESTION IS : How to export the Polygon Type geometry into separated with alembic? Quote Link to comment Share on other sites More sharing options...
calix Posted March 12, 2013 Share Posted March 12, 2013 Hi WangHuan! See attached HIP-File...the primitive type "Mesh" had no primitive numbers so I simply converted it to a polymesh to get it working. Have fun! calix exportGEO_problem_fixed.hip Quote Link to comment Share on other sites More sharing options...
