Gubkin 1 Posted January 21, 2015 (edited) Hello everyone I have got a sphere activating fractured geometry by going through it. I am using a foreach node with a centroid expression inside to add point to each piece which is then activated by the sphere via attribute transfer. Then I am using a point expression on a activevalue in the DOP to activate the pieces by the colour that the sphere transfers to the points. I want to know how to make the pieces that activate stay activated forever without deactivating once the sphere is gone. Any ideas? Thanks. activate_pieces.hipnc Edited January 22, 2015 by Gubkin Share this post Link to post Share on other sites
stovetop 0 Posted January 22, 2015 (edited) You could use the SOP solver to change the activate state from 0 to 1. create an active attribute on the sphere volume and do an attribute transfer from the sphere to the fractured object inside of the sop solver. This will keep the new values as the sim runs... just make sure that the fractured pieces aren't active at the start...which will give them an active value of 0 here's an example activeSopSolver.hipnc Edited January 22, 2015 by stovetop Share this post Link to post Share on other sites
Gubkin 1 Posted January 22, 2015 (edited) Thanks, stovetop for your reply. When I opened your scene I got a massive list of "skipping unrecognized" stuff and it didn't work but you mentioning the SOP Solver made me test a few things and it worked, so thank you Here is the working file activate_pieces_forever.hipnc Edited January 22, 2015 by Gubkin Share this post Link to post Share on other sites
