cwalrus Posted January 19, 2016 Share Posted January 19, 2016 Can anyone tell me why this isn't working? I was hoping to color the geo based on the velocity of the fragments. Velocity = red amount... see file thanks! Destruction_01.hipnc Quote Link to comment Share on other sites More sharing options...
rich_lord Posted January 20, 2016 Share Posted January 20, 2016 You had created the v attribute on the points. The attribVOP was looking for it on the primitives. I used an attribute promote SOP to put the velocity data onto the primitives so it could be read in the attribVOP The other thing I added in the attibVOP was a bind export node so I could measure the length of the velocity vector to set the fit range node correctly. You had it set to -1 to 1 I think. The full velocity range was around 0 to 42. Destruction_01.hipnc 1 Quote Link to comment Share on other sites More sharing options...
cwalrus Posted January 20, 2016 Author Share Posted January 20, 2016 Thanks so much- you answered two other questions I didn't even ask - "How can I see the Length, and what does a Bind node do?" !! Quote Link to comment Share on other sites More sharing options...
jon3de Posted January 20, 2016 Share Posted January 20, 2016 Couldn´t have a look on the file at the moment but you can export the length of the the vector via a bind export as a geometry attribute and have a look on that in the geometry spreadsheet. So he knew how to set the parameters on the fit range. As rich_lord already wrote. so I could measure the length of the velocity vector to set the fit range node correctly. You had it set to -1 to 1 I think. The full velocity range was around 0 to 42. @rich_lord pls correct me if I´m wrong. Quote Link to comment Share on other sites More sharing options...
