Does anyone know how I can access the boolean value I'm setting with the Modify Data node in DOPS. Basically following this (page 121) but it doesn't actually explain how to use the dopfield expression to access the boolean. I would like to use it to activate a force. EDIT: After reading as many forums as possible I'm still stuck. But, I think I need to initialize my data with an Empty Data node? Still my dopfield expression doesn't work. -
I've a pre_fracture sphere that is falling down on ground as RBD Fractured Object. When it hits ground, it breaks apart and emit particles on collision(Impacts). I used two methods for that. In method_01 I created an add node which creates a point for each impact at the proper position using dopfield function. Then I added a copy node to create a point for each record on the object using dopnumrecords function. Then I append another copy node to get the number of RBD fracture pieces and make a copy for each using to arg expressions. Finally I created a popnet node to emit particles on impacts. Every thing works fine, except emitting unnecessary particles on origin(0,0,0). In methode_02 I created an add node with single point and appended copy to copy that point as many times as Impacts occurred using dopnumrecords function in number of copies field. Then I added a point sop to get the exact positions of pieces using dopfield expression in Position field. The I copied a grid on those points. Finally I added a popnet. In this case particles are being emitted only from first piece which objID is 0 (in my case that is piece0 and objID is 2). I attached my hip file. Kindly help. dust_from_RBD.hipnc
