seth_ro18 Posted March 19, 2010 Share Posted March 19, 2010 I have a POP Network set up inside a SOP Network, and I want to import the POP's Geometry data into a DOP Network. What is the best way to do that? When I use a POP Object node, it imports the initial point positions, but it does not update the particles nor does it import the POP's group information. If I output the POP Network to a SOP node (e.g. a Null), then use a SOP Geometry node to read the points into the DOP, it does not read in any of the Geometry. Do I have to set up the POP Network inside the DOP? What's the best way to go about this? Thanks! Quote Link to comment Share on other sites More sharing options...
zglynn Posted March 19, 2010 Share Posted March 19, 2010 Hey Seth Use a sop geometry node to bring in your pop net through the "SOP Path". Then there are several nodes ("gas particle ____") that you can use, depending on what you are doing, to manipulate your particular dop solver. Hope that helps Zach Quote Link to comment Share on other sites More sharing options...
seth_ro18 Posted March 19, 2010 Author Share Posted March 19, 2010 Hi, For some reason it's not transferring my data over, or so it seems. When I look at the details view of the SOP Geometry node, it has no Geometry information or anything. However, all the points are there in the POP Network. Also, my point attribute and group information does not transfer. In case it helps, I'm attaching an example file: POPtoDOP.hipnc Quote Link to comment Share on other sites More sharing options...

You need to connect the Geometry data to a object. Put down a empty object node and pipe it into the sopgeo. Since the POPnet is "deforming" you also need to read it in every frame, set the sop path and Time parameters to Set Always and in time field set $T.

zglynn Posted March 19, 2010 Share Posted March 19, 2010 Here is another way to get particles into DOPS Zach POPtoDOP.hipnc Quote Link to comment Share on other sites More sharing options...
