jackassol Posted January 21, 2017 Share Posted January 21, 2017 (edited) Hello guys, i have a simple setup with an dop network. For some reasons i lose my normals? (not sure) when my geometry is calculated over the dopnet. I wanted o copy some tubes on the "big tentacles" but the copied cubes did copying in the normals direction. Picture 1: wrong normal direction after dopnet Picture 2: right - i want to achieve this i uploaded my file here swell best Edited January 23, 2017 by jackassol Quote Link to comment Share on other sites More sharing options...

dimovfx Posted January 23, 2017 Share Posted January 23, 2017 try to delete "orient" and "v" point attributes after the DOP. 2 Quote Link to comment Share on other sites More sharing options...

jackassol Posted January 25, 2017 Author Share Posted January 25, 2017 (edited) next problem: The normal direction is changeing after the first frame . Does anyone know how to fix that? Picture 1: right - i want to achieve this over the hole animation Picture 2: wrong normal direction after the first frame Edited January 25, 2017 by jackassol Quote Link to comment Share on other sites More sharing options...

Sepu Posted January 25, 2017 Share Posted January 25, 2017 turn off the "UP_DIRECTION" copy2.hipnc Quote Link to comment Share on other sites More sharing options...
Gavin Posted January 25, 2017 Share Posted January 25, 2017 The problem isn't that your normals are changing, but rather that they aren't changing with your geo as it deforms. Removing your "UP_DIRECTION" will force the normals to be recalculated as the shapes are copied and thus they will go with the deformed geometry. However, Im guessing you want to use the special vectors you calculated in that node to direct your copied pieces. So keep "UP_DIRECTION" on and use a "rotate by quaternion" along with the orient attribute to modify the normals as the object deforms. As a side note remember that the normals you are using for copying are probably not the ones you want to be using for any rendering, so adjust accordingly. copy.hipnc 2 Quote Link to comment Share on other sites More sharing options...
